- Touch Sensor : Cypress CY8C4014LQI
- RGB LED driver : TI LP55231 (2x)
- LEDs/Keys : 11x, 6x
- UART : through-hole on PCB
- J1: 3.3V, TX, RX, GND from tri-angle marking
- 115200n8
- Power : 12 VDC, 2.5 A
Flash instruction using initramfs image:
1. Prepare TFTP server with the IP address 192.168.132.100 and place the
initramfs image to TFTP directory with the name "C0A88401.img"
2. Boot NCP-HG100/Cellular and interrupt after the message
"Hit any key to stop autoboot: 2"
3. Perform the following commands and set bootcmd to allow booting from
eMMC
setenv bootcmd "mmc read 0x84000000 0x2e22 0x4000 && bootm 0x84000000"
saveenv
4. Perform the following command to load/boot the OpenWrt initramfs image
tftpboot && bootm
5. On the initramfs image, perform sysupgrade with the sysupgrade image
(if needed, backup eMMC partitions by dd command and download to
other place before performing sysupgrade)
6. Wait for ~120 seconds to complete flashing
Known issues:
- There are no drivers for audio-related chips/functions in Linux Kernel
and OpenWrt, they cannot be used.
- There is no driver for MINI54FDE Micro-Controller Unit, customized for
this device by the firmware in the MCU. This chip controls the
following functions, but they cannot be controlled in OpenWrt.
- RGB LED
- Fan
this fan is controlled automatically by MCU by default, without
driver
- Thermal Sensors (2x)
- Currently, there is no driver or tool for CY8C4014LQI and cannot be
controlled. It cannot be exited from "booting mode" and moved to "normal
op mode" after booting. And also, the 4x buttons (mic mute, vol down,
vol up, alexa trigger) connected to the IC cannot be controlled.
- it can be exited from "booting mode" by installing and executing
i2cset command:
opkg update
opkg install i2c-tools
i2cset -y 1 0x14 0xf 1
- There is a connection issue on the control by uqmi for the WWAN module.
But modemmanager can be used without any issues and the use of it is
recommended.
- With the F2FS format, too many errors are reported on erasing eMMC
partition "rootfs_data" while booting:

Note:
- The primary uart is shared for debug console and Z-Wave chip. The
function is switched by GPIO15 (Linux: 427).
value:
1: debug console
0: Z-Wave
- NCP-HG100/Cellular has 2x os-image pairs in eMMC.
- 0:HLOS, rootfs
- 0:HLOS_1, rootfs_1
In OpenWrt, the first image pair is used.
- "bootipq" command in U-Boot requires authentication with signed-image
by default. To boot unsigned image of OpenWrt, use "mmc read" and
"bootm" command instead.
- This support is for "Cellular" variant of NCP-HG100 and not tested on
"WLAN" (non-cellular) variant.
- The board files of ipq-wifi may also be used in "WLAN" variant of
NCP-HG100, but unconfirmed and add files as for "Cellular" variant.
- "NET" LED is used to indicate WWAN status in stock firmware.
- There is no MAC address information in the label on the case, use the
address included in UUID in the label as "label-MAC" instead.
- The "CLOUD" LEDs are partially used for indication of system status in
stock firmware, use they as status LEDs in OpenWrt instead of RGB LED
connected to the MCU.

LHGG-60ad is IPQ4019 + wil6210 based.
Specification:
- Qualcomm IPQ4019 (717 MHz)
- 256 MB of RAM (DDR3L)
- 16 MB (SPI NOR) of flash
- 1x Gbit ethernet, 802.3af/at POE IN connected through AR8035.
- WLAN: wil6210 802.11ad PCI card
- No USB or SD card ports
- UART disabled
- 8x LEDs
Biggest news is the wil6210 PCI card.
Integration for its configuration and detection has already been taken
care of when adding support for TP-Link Talon AD7200.
However, signal quality is much lower than with stock firmware, so
probably additional board-specific data has to be provided to the
driver and is still missing at the moment.

So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.
Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

This patch does the following:
- move WiFi LED setup to DTS
- fix LAN/WAN MAC addresses and add label MAC address
- wan5G -> wlan5G, power -> led_power
- increase flash SPI frequency to 30MHz
MAC addresses are stored in Factory partition at:
0x1006: WiFi 2.4GHz, WAN (label_mac)
0x5006: WiFi 5GHz, LAN (label_mac +4)
By improving flash speed,
`time dd if=/dev/mtdblock8 of=/dev/null bs=2k`
is reduced from 7m 10.26s to 5m 9.52s.

There is currently no way back to factory firmware, so this is a one-way

1) Enable SSH and disable the CLI on the factory device from the web user

2) Reboot the device
3) Override the default, limited SSH shell:
a) Get into the ssh shell:
ssh admin@192.168.1.1 /bin/sh --login
b) Change the dropbear script to disable the limited shell. At the
empty command prompt type:
sed -i '/login_ssh/s/^/#/g’ dropbear
/etc/init.d/dropbear restart
exit
4) ssh in to a (now-) normal OpenWRT SSH session
5) Flash your built image
a) scp openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin
admin@192.168.1.1:/tmp/
b) ssh admin@192.168.1.1
c) sysupgrade -n
/tmp/openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin
6) After flash completes (it may say "Upgrade failed" followed by
"Upgrade completed") and device reboots, log in to newly flashed
system. Note you will now need to ssh as root rather than admin.

Installation
------------
1. Grab the uboot for the Device from the 'u-boot-fritz7530'
subdirectory. Place it in the same directory as the 'eva_ramboot.py'
script. It is located in the 'scripts/flashing' subdirectory of the
OpenWRT tree.
2. Assign yourself the IP address 192.168.178.10/24. Connect your
Computer to one of the boxes LAN ports.
3. Connect Power to the Box. As soon as the LAN port of your computer
shows link, load the U-Boot to the box using following command.
> ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz7530.bin
4. The U-Boot will now start. Now assign yourself the IP address
192.168.1.70/24. Copy the OpenWRT initramfs (!) image to a TFTP
server root directory and rename it to 'FRITZ7530.bin'.
5. The Box will now boot OpenWRT from RAM. This can take up to two
minutes.
6. Copy the U-Boot and the OpenWRT sysupgrade (!) image to the Box using
scp. SSH into the Box and first write the Bootloader to both previous
kernel partitions.
> mtd write /path/to/uboot-fritz7530.bin uboot0
> mtd write /path/to/uboot-fritz7530.bin uboot1
7. Remove the AVM filesystem partitions to make room for our kernel +
rootfs + overlayfs.
> ubirmvol /dev/ubi0 --name=avm_filesys_0
> ubirmvol /dev/ubi0 --name=avm_filesys_1
8. Flash OpenWRT peristently using sysupgrade.
> sysupgrade -n /path/to/openwrt-sysupgrade.bin

1. Load Ramdisk via U-Boot
To set up the flash memory environment, do the following:
a. As a preliminary step, ensure that the board console port is connected to the PC using these RS232 parameters:
* 115200bps
* 8N1
b. Confirm that the PC is connected to the board using one of the Ethernet ports. Set a static ip 192.168.99.8 for Ethernet that connects to board. The PC must have a TFTP server launched and listening on the interface to which the board is connected. At this stage power up the board and, after a few seconds, press 4 and then any key during the countdown.
U-BOOT> set serverip 192.168.99.8 && set ipaddr 192.168.99.9 && tftpboot 0x84000000 openwrt.itb && bootm
2. Load image via GUI
a. Upgrade EAP1300 to FW v3.5.3.2
In the GUI, System Manager > Firmware > Firmware Upgrade, to do upgrade.
b. Transfer to OpenWrt from EnGenius.
In Firmware Upgrade page, to upgrade yours openwrt-ipq40xx-engenius_eap1300-squashfs-sysupgrade.bin.
3. Revert to EnGenius EAP1300

The Serial setting is 115200-8-N-1. The board has a populated
1x4 0.1" header with half-height/low profile pins.
The pinout is: VCC (little white arrow), RX, TX, GND.
Flashing needs a serial adaptor, as well as patched ubootwrite utility
(needs Little-Endian support). And a modified u-boot (enabled Ethernet).
Meraki's original u-boot source can be found in:
<https://github.com/riptidewave93/meraki-uboot/tree/mr33-20170427>
Add images to do an installation via bootloader:
0. open up the MR33 and connect the serial console.
1. start the 2nd stage bootloader transfer from client pc:
# ubootwrite.py --write=mr33-uboot.bin
(The ubootwrite tool will interrupt the boot-process and hence
it needs to listen for cues. If the connection is bad (due to
the low-profile pins), the tool can fail multiple times and in
weird ways. If you are not sure, just use a terminal program
and see what the device is doing there.
2. power on the MR33 (with ethernet + serial cables attached)
Warning: Make sure you do this in a private LAN that has
no connection to the internet.
- let it upload the u-boot this can take 250-300 seconds -
3. use a tftp client (in binary mode!) on your PC to upload the sysupgrade.bin
(the u-boot is listening on 192.168.1.1)
# tftp 192.168.1.1
binary
put openwrt-ipq40xx-meraki_mr33-squashfs-sysupgrade.bin
4. wait for it to reboot
5. connect to your MR33 via ssh on 192.168.1.1
For more detailed instructions, please take a look at the:
"Flashing Instructions for the MR33" PDF. This can be found

PCB right next to the connector.
U-Boot Note: The ethernet driver isn't always reliable and can sometime

Access via the serial console is required. As well as a working
TFTP-server setup and the initramfs image. (If not provided, it
has to be built from the OpenWrt source. Make sure to enable
LZMA as the compression for the INITRAMFS!)
To install the image permanently, you have to do the following
steps in the listed order.
1. Open up the router.
There are four phillips screws hiding behind the four plastic
feets on the underside.
2. Connect the serial cable (See notes above)
3. Connect your router via one of the four LAN-ports (yellow)
to a PC which can set the IP-Address and ssh and scp from.
If possible set your PC's IPv4 Address to 192.168.1.70
(As this is the IP-Address the Router's bootloader expects
for the tftp server)
4. power up the router and enter the u-boot
choose option 1 to upload the initramfs image. And follow
through the ipv4 setup.
Wait for your router's status LED to stop blinking rapidly and
glow just blue. (The LAN LED should also be glowing blue).
