With 5.15 kernel version Linksys EAX500 family devices suffered from a
big regression where the Ethernet switch became silent and started to
malfunction.
It was discovered later that the cause was not really the kernel upgrade
itself but a hackish implementation of the hw implementation of these
special routers.
In the original Linksys source code, GPIO 63 was handled in a special way
and was reset on reboot.
Normally GPIO 63 is used for pcie2 reset but in every device we support,
pcie2 is actually never used as nothing is attached to it.
Linksys rerouted GPIO 63 to the switch reset pin and deviates from
common hw implementation.
Till now it was used an hack to handle this case... It was set pcie3 as
working (while actually nothing was connected), set it to output low
(for assert-deassert from the pcie init code) and be done with it.
The result was that the GPIO was reset for enough time in early boot and
everything worked correctly.
This hack implementation was born to fail from the very start and in
kernel 5.15 finally problem arised.
In 5.15 pcie code changed and now the GPIO reset pin is not asserted as
probe won't fail if nothing is connected to the line (the old behaviour)
This result in the switch hold the reset pin and the Ethernet switch
dead.
On top of that with 5.15 code got optimized and simply attaching the
GPIO reset to the mdio wasn't enough as the switch require at least 10ms
to be correctly reset.
So implement finally a correct solution where:
- pcie2 is correctly disabled (nothing attached, unused)
- drop the wrong output-low for pcie2 reset pin
- define GPIO 63 as switch reset
- Add the reset-gpios to the mdio0 node
- Set the reset-post-delay-us to 12ms to correctly give time the switch
to reset

Similar to commit 4d8b42d8a7 ("ipq40xx: point to externally compiled
dtbs in recipes").
Currently, we patch our DTS files into the kernel source tree, so the
kernel build process will produce DTBs for us. The kernel-to-DTS
dependency can cause buildroot to perform excessive rebuilds of the
kernel though, which slows down device development iteration.
Buildroot also compiles DTBs on its own, to
$(KDIR)/image-$(DEVICE_DTS).dtb. With small adjustments, we can leverage
this, and stop patching DTS files into the kernel Makefile at the same
time.

IMPORTANT:
This port requires moving the 'fw_env' partition prior to first boot to
consolidate 70% of the usable space in flash into a contiguous partition.
'fw_env' contains factory-programmed MAC addresses, SSIDs, and passwords.
Its contents must be copied to 'rootfs_1' prior to booting via initramfs.
Note that the stock 'fw_env' partition will be wiped during sysupgrade.
A writable 'stock_fw_env' partition pointing to the old, stock location
is included in the port to help rolling back this change if desired.
Installation:
- Requires serial access and a TFTP server.
- Fully boot stock, press ENTER, type in:
mtd erase /dev/mtd21
dd if=/dev/mtd22 bs=128K count=1 | mtd write - /dev/mtd21
umount /config && ubidetach -m 23 && mtd erase /dev/mtd23
- Reboot and interrupt U-Boot by pressing a key, type in:
set mtdids 'nand0=nand0'
set mtdparts 'mtdparts=nand0:155M@0x6500000(mtd_ubi)'
set bootcmd 'ubi part mtd_ubi && ubi read 0x44000000 kernel && bootm'
env save
- Setup TFTP server serving initramfs image as 'recovery.bin', type in:
set ipaddr 192.168.1.1
set serverip 192.168.1.2
tftpboot recovery.bin && bootm
- Use sysupgrade to install squashfs image.

[add 5.15 changes for 0069-arm-boot-add-dts-files.patch]
Signed-off-by: Sungbo Eo <mans0n@gorani.run>
The existing device tree has incorrect definitions for usb3_0 and usb3_1
and the blocks they depend upon: their addresses and interrupts are
swapped. However, their clocks and resets are not. The result is that
the USB blocks are non-functional if only one of them is enabled.
This fix backports the definitions from mainline Linux 5.15 to
OpenWrt's 5.10 dtsi additions. See the relevant mainline code here:
https://github.com/torvalds/linux/blob/v5.17/arch/arm/boot/dts/qcom-ipq8064.dtsi#L1062-L1148
This fix does not break existing ports. But some ports may have enabled
both USB blocks even thought their board only implements one, because
enabling a single USB block would not have worked before this fix.
This means that revisiting all ports of ipq806x devices that implement
a single USB port is advised. This work must be done by maintainers that
can determine which USB block corresponds to the implemented port on
their hardware.
Note that this fix swaps the names of the hardware ports. This is
unfortunate, but will happen anyway when switching to kernel 5.15. Thus,
it is best to do this ASAP, before users get to depend on port names.
It is strongly recommended that this fix is backported to 22.03 before
its release. This will minimize the number of users affected by the port
name swap.

This fixes the MMC failing to initialize on newer ZyXEL NBG6817
hardware revisions with Kingston MMC. Older revisions should
hopefully be unaffected.
Check MMC hardware details with:
cd /sys/block/mmcblk0/device/ && \
tail -v cid date name manfid fwrev hwrev oemid rev
Known problematic MMC names (broken before this commit):
* M62704 (dated 12/2018) via myself
* M62704 (dated 11/2018) via Drake Stefani
Known unaffected MMC names (already working without this commit):
* S10004 (dated 12/2015) via slh
Without enabling dynamic debugging, this error manifests in the kernel
hardware serial console as the following:
[ 2.746605] mmc0: error -110 whilst initialising MMC card
[…trimmed other messages…]
[ 2.877832] Waiting for root device /dev/mmcblk0p5...
Enabling Linux dynamic kernel debugging provides additional messages.
For guidance, see the Linux kernel documentation:
https://www.kernel.org/doc/html/latest/admin-guide/dynamic-debug-howto.html
First, enable dynamic debugging in OpenWRT's configuration:
1. Run "make menuconfig"
2. Select "Global build settings --->"
3. Select "Kernel build options --->"
4. Enable "Compile the kernel with dynamic printk" via spacebar
5. Save and exit (arrow key to "Exit" until prompted to save, save)
Alternatively, set "CONFIG_KERNEL_DYNAMIC_DEBUG=y" in your .config.
Then, turn on dynamic debugging at boot:
Modify bootargs in
target/linux/ipq806x/files/arch/arm/boot/dts/qcom-ipq8065-nbg6817.dts
to add…
bootargs = "[…existing bootargs…] dyndbg=\"file drivers/mmc/* +p\" dynamic_debug.verbose=1 loglevel=8";
For example:
chosen {
- bootargs = "rootfstype=squashfs,ext4 rootwait noinitrd fstools_ignore_partname=1";
+ bootargs = "rootfstype=squashfs,ext4 rootwait noinitrd fstools_ignore_partname=1 dyndbg=\"file drivers/mmc/* +p\" dynamic_debug.verbose=1 loglevel=8";
append-rootblock = "root=/dev/mmcblk0p";
Then, compile and flash the resulting build. If you are testing
before this commit on newer MMC hardware, be prepared to recover!
NOTE: If you have hardware serial console access, you don't need to
use TFTP recovery to change the active boot partition.
Reboot to working alternative partition via serial console:
1. Connect to hardware serial console
* See https://openwrt.org/toh/zyxel/nbg6817#serial
2. Interrupt boot at "Hit any key to stop autoboot:"
3. Run "ATSE NBG6817"
4. Copy the result (e.g. "001976FE4B04")
* Changes with **every boot** - can't reuse this
5. On your local system, run
"./zyxel-uboot-password-tool.sh <copied value here>"
* Example: "./zyxel-uboot-password-tool.sh 001976FE4B04"
6. Run the command provided by the password tool
* Example: "ATEN 1,910F129B"
* Changes with **every boot** - can't reuse this
7. Run "ATGU"
* You now have full u-boot shell until next boot - unlocking is
not remembered
8. Run either "run boot_mmc" (for booting partition set "FF") or
"run boot_mmc_1" (for booting partition set "01")
* These commands are not affected by dual-boot partition flags
NOTE: This will NOT set the dual-boot partition flag. You'll need to
fix that manually. The "nbg6817-dualboot" script may help:

The MR42 and MR52 are two similar IPQ806x based devices from the Cisco
Meraki "Cryptid" series.
MR42 main features:
- IPQ8068 1.4GHz
- 512MB RAM
- 128MB NAND
- 2x QCA9992 (2.4 & 5GHz)
- 1x QCA9889 (2.4 & 5GHz)
- 1x AR8033 PHY
- PoE/AC power
MR52 main features:
- IPQ8068 1.4GHz
- 512MB RAM
- 128MB NAND
- 2x QCA9994 (2.4 & 5GHz)
- 1x QCA9889 (2.4 & 5GHz)
- 2x AR8033 PHYs
- PoE/AC power
(MR42 Only) Installation via diagnostic mode:
If you can successfully complete step 1 then you can continue to install
via this method without having to open the device. Otherwise please use
the standard UART method. Please note that when booting via TFTP, some
Ethernet devices, in particular those on laptops, will not connect in
time, resulting in TFTP boot not succeeding. In this instance it is
advised to connect via a switch.
1. Hold down reset at power on and keep holding, after around 10 seconds
if the orange LED changes behaviour to begin flashing, proceed to
release reset, then press reset two times. Ensure that the LED has
turned blue. Note that flashing will occur on some devices, but it
will not be possible to change the LED colour using the reset button.
In this case it will still be possible to continue with this install
method.
2. Set your IP to 192.168.1.250. Set up a TFTP server serving
mr42_u-boot.mbn and
openwrt-ipq806x-generic-meraki_mr42-initramfs-fit-uImage.itb, obtained
from [1].
3. Use telnet and connect to 192.168.1.1. Run the following commands to
install u-boot. Note that all these commands are critical, an error
will likely render the device unusable.
Option 3.1:
If you are sure you have set up the TFTP server correctly you can
run this script on the device. This will download and flash the
u-boot image immediately:
`/etc/update_uboot.sh 192.168.1.250 mr42_u-boot.mbn`
Once completed successfully, power off the device.
Option 3.2:
If you are unsure the TFTP server is correctly set up you can
obtain the image and flash manually:
3.2.1. `cd /tmp`
3.2.2. `tftp-hpa 192.168.1.250 -m binary -c get mr42_u-boot.mbn`
3.2.3. Confirm file has downloaded correctly by comparing the
md5sum:
`md5sum mr42_u-boot.mbn`
3.2.4. The following are the required commands to write the image.
`echo 1 > /sys/devices/platform/msm_nand/boot_layout
mtd erase /dev/mtd1
nandwrite -pam /dev/mtd1 mr42_u-boot.mbn
echo 0 > /sys/devices/platform/msm_nand/boot_layout`
Important: You must observe the output of the `nandwrite`
command. Look for the following to verify writing is occurring:
`Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000`
If you do not see this then do not power off the device. Check
your previous commands and that mr42_u-boot.mbn was downloaded
correctly. Once you are sure the image has been written you
can proceed to power off the device.
4. Hold the reset button and power on the device. This will immediately
begin downloading the appropriate initramfs image and boot into it.
Note: If the device does not download the initramfs, this is likely
due to the interface not being brought up in time. Changing Ethernet
source to a router or switch will likely resolve this. You can also
try manually setting the link speed to 10Mb/s Half-Duplex.
5. Once a solid white LED is displayed on the device, continue to the
UART installation method, step 6.
Standard installation via UART - MR42 & MR52
1. Disassemble the device and connect a UART header. The header pinout
is as follows:
1 - 3.3v
2 - TXD
3 - RXD
4 - GND
Important: You should only connect TXD, RXD and GND. Connecting
3.3v may damage the device.
2. Set your IP to 192.168.1.250. Set up a TFTP server serving
openwrt-ipq806x-generic-meraki_(mr42|mr52)-initramfs-fit-uImage.itb.
Separately obtain the respective sysupgrade image.
3. Run the following commands, preferably from a Linux host. The
mentioned files, including ubootwrite.py and u-boot images, can be
obtained from [1].
`python ubootwrite.py --write=(mr42|mr52)_u-boot.bin`
The default for "--serial" option is /dev/ttyUSB0.
4. Power on the device. The ubootwrite script will upload the image to
the device and launch it. The second stage u-boot will in turn load
the initramfs image by TFTP, provided the TFTP server is running
correctly. This process will take about 13 minutes. Once a solid
white LED is displayed, the image has successfully finished
loading. Note: If the image does not load via TFTP, try again with
the Ethernet link to 10Mb/s Half-Duplex.
5. (MR42 only) Do not connect over the network. Instead connect over
the UART using minicom or similar tool. To replace u-boot with
the network enabled version, please run the following commands.
Note that in the provided initramfs images, the u-boot.mbn file
is located in /root:
If you have not used the provided initramfs, you must ensure you
are using an image with "boot_layout" ECC configuration enabled in
the Kernel. This will be version 5.10 or higher. If you do not do
this correctly the device will be bricked.
`insmod mtd-rw i_want_a_brick=1
mtd erase /dev/mtd8
nandwrite -pam /dev/mtd8 /root/mr42_u-boot.mbn`
After running nandwrite, ensure you observe the following output:
`Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000`
6. (Optional) If you have no further use for the Meraki OS, you can
remove all other UBI volumes on ubi0 (mtd11), including diagnostic1,
part.old, storage and part.safe. You must not remove the ubi1 ART
partition (mtd12).
`for i in diagnostic1 part.old storage part.safe ; do
ubirmvol /dev/ubi0 -N $i
done`
7. Proceed to flash the sysupgrade image via luci, or else download or
scp the image to /tmp and use the sysupgrade command.

Installation:
Install via Web Interface (preferred):
Utilize openwrt-ipq806x-netgear_xr500-squashfs-factory.img
Install via TFTP recovery:
1.Turn off the power, push and hold the reset button (in a hole on
backside) with a pin
2.Turn on the power and wait till power led starts flashing white
(after it first flashes orange for a while)
3.Release the reset button and tftp the factory img in binary mode.
The power led will stop flashing if you succeeded in transferring
the image, and the router reboots rather quickly with the new
firmware.
4.Try to ping the router (ping 192.168.1.1). If does not respond,
then tftp will not work either.
Uploading the firmware image with a TFTP client
$ tftp 192.168.1.1
bin
put openwrt-ipq806x-netgear_xr500-squashfs-factory.img
Note:
The end of the last partition is at 0xee00000. This was chosen
by the initial author, but nobody was able to tell why this
particular arbitrary size was chosen. Since it's not leaving
too much empty space and it's the only issue left, let's just
keep it for now.

Rearrange all voltage triplets for "opp_table0" to match the
specifications. "opp-microvolt" and "opp-microvolt-<name>" triplets
are in order of <target min max>, and NOT <min target max>.
Previously, the CPU would *always* spend its time at the "minimum"
voltage, ignoring the actual intended target. This is a regression
from previous behavior.
On an NBG6817 with a Qualcomm CPU of PVS bin #2...
(see &opp_table0 -> opp-1725000000 -> opp-microvolt-speed0-pvs2-v0)

This adds support for the Askey RT4230W REV6
(Branded by Spectrum/Charter as RAC2V1K)
At this time, there's no way to reinstall the stock firmware so don't install
this on a router that's being rented.
Specifications:
Qualcomm IPQ8065
1 GB of RAM (DDR3)
512 MB Flash (NAND)
2x Wave 2 WiFi cards (QCA9984)
5x 10/100/1000 Mbps Ethernet (Switch: QCA8337)
1x LED (Controlled by a microcontroller that switches it between red and
blue with different patterns)
1x USB 3.0 Type-A
12V DC Power Input
UART header on PCB - pinout from top to bottom is RX, TX, GND, 5V
Port settings are 115200n8
More information: https://forum.openwrt.org/t/askey-rac2v1k-support/15830https://deviwiki.com/wiki/Askey_RAC2V1K
To check what revision your router is, restore one of these config backups
through the stock firmware to get ssh access then run
"cat /proc/device-tree/model".
https://forum.openwrt.org/t/askey-rac2v1k-support/15830/17
The revision number on the board doesn't seem to be very consistent so that's
why this is needed. You can also run printenv in the uboot console and if
machid is set to 177d, that means your router is rev6.
Note: Don't install this if the router is being rented from an ISP. The defined
partition layout is different from the OEM one and even if you changed the
layout to match, backing up and restoring the OEM firmware breaks /overlay so
nothing will save and the router will likely enter a bootloop.
How to install:
Method 1: Install without opening the case using SSH and tftp
You'll need:
RAC2V1K-SSH.zip:
https://github.com/lmore377/openwrt-rt4230w/blob/master/RAC2V1K-SSH.zip
initramfs and sysupgrade images
Connect to one of the router's LAN ports
Download the RAC2V1K-SSH.zip file and restore the config file that
corresponds to your router's firmware (If you're firmware is newer than what's
in the zip file, just restore the 1.1.16 file)
After a reboot, you should be able to ssh into the router with username:
"4230w" and password: "linuxbox" or "admin". Run the following commannds
fw_setenv ipaddr 10.42.0.10 #IP of router, can be anything as long as
it's in the same subnet as the server
fw_setenv serverip 10.42.0.1# #IP of tftp server that's set up in next
steps
fw_setenv bootdelay 8
fw_setenv bootcmd "tftpboot initramfs.bin; bootm; bootipq"
Don't reboot the router yet.
Install and set up a tftp server on your computer
Set a static ip on the ethernet interface of your computer (use this for
serverip in the above commands)
Rename the initramfs image to initramfs.bin, and host it with the tftp
server
Reboot the router. If you set up everything right, the router led should
switch over to a slow blue glow which means openwrt is booted. If for some
reason the file doesn't get loaded into ram properly, it should still boot to
the OEM firmware.
After openwrt boots, ssh into it and run these commands:
fw_setenv bootcmd "setenv mtdids nand0=nand0 && setenv mtdparts
mtdparts=nand0:0x1A000000@0x2400000(firmware) && ubi part firmware && ubi
read 0x44000000 kernel 0x6e0000 && bootm"
fw_setenv bootdelay 2
After openwrt boots up, figure out a way to get the sysupgrade file onto it
(scp, custom build with usb kernel module included, wget, etc.) then flash it
with sysupgrade. After it finishes flashing, it should reboot, the light should
start flashing blue, then when the light starts "breathing" blue that means
openwrt is booted.
Method 2: Install with serial access (Do this if something fails and you can't
boot after using method 1)
You'll need:
initramfs and sysupgrade images
Serial access:
https://openwrt.org/inbox/toh/askey/askey_rt4230w_rev6#opening_the_case
Install and set up a tftp server
Set a static ip on the ethernet interface of your computer
Download the initramfs image, rename it to initramfs.bin, and host it with
the tftp server
Connect the wan port of the router to your computer
Interrupt U-Boot and run these commands:
setenv serverip 10.42.0.1 (You can use whatever ip you set for the computer)
setenv ipaddr 10.42.0.10 (Can be any ip as long as it's in the same subnet)
setenv bootcmd "setenv mtdids nand0=nand0 &&
set mtdparts mtdparts=nand0:0x1A000000@0x2400000(firmware) && ubi part firmware
&& ubi read 0x44000000 kernel 0x6e0000 && bootm"
saveenv
tftpboot initramfs.bin
bootm
After openwrt boots up, figure out a way to get the sysupgrade file onto it
(scp, custom build with usb kernel module included, wget, etc.) then flash it
with sysupgrade. After it finishes flashing, it should reboot, the light should
start flashing blue, then when the light starts "breathing" blue that means
openwrt is booted.

With some talk with the ARM maintainer, it was notice that enlarging the limit
to the current value is VERY wrong and clash with other memory.
A better solution would be to reduce the IO space from 1MB to 64K as probably
it's a long lasting typo and even x86 arch doesn't have a IO space that big.
