Huawei AP5030DN is a dual-band, dual-radio 802.11ac Wave 1 3x3 MIMO
enterprise access point with two Gigabit Ethernet ports and PoE
support.
Hardware highlights:
- CPU: QCA9550 SoC at 720MHz
- RAM: 256MB DDR2
- Flash: 32MB SPI-NOR
- Wi-Fi 2.4GHz: QCA9550-internal radio
- Wi-Fi 5GHz: QCA9880 PCIe WLAN SoC
- Ethernet 1: 10/100/1000 Mbps Ethernet through Broadcom B50612E PHY
- Ethernet 2: 10/100/1000 Mbps Ethernet through Marvell 88E1510 PHY
- PoE: input through Ethernet 1 port
- Standalone 12V/2A power input
- Serial console externally available through RJ45 port
- External watchdog: SGM706 (1.6s timeout)
Serial console:
9600n8 (9600 baud, no stop bits, no parity, 8 data bits)
MAC addresses:
Each device has 32 consecutive MAC addresses allocated by
the vendor, which don't overlap between devices.
This was confirmed with multiple devices with consecutive
serial numbers.
The MAC address range starts with the address on the label.
To be able to distinguish between the interfaces,
the following MAC address scheme is used:
- eth0 = label MAC
- eth1 = label MAC + 1
- radio0 (Wi-Fi 5GHz) = label MAC + 2
- radio1 (Wi-Fi 2.4GHz) = label MAC + 3
Installation:
0. Connect some sort of RJ45-to-USB adapter to "Console" port of the AP
1. Power up the AP
2. At prompt "Press f or F to stop Auto-Boot in 3 seconds",
do what they say.
Log in with default admin password "admin@huawei.com".
3. Boot the OpenWrt initramfs from TFTP using the hidden script
"run ramboot". Replace IP address as needed:
> setenv serverip 192.168.1.10
> setenv ipaddr 192.168.1.1
> setenv rambootfile
openwrt-ath79-generic-huawei_ap5030dn-initramfs-kernel.bin
> saveenv
> run ramboot
4. Optional but recommended as the factory firmware cannot
be downloaded publicly:
Back up contents of "firmware" partition using the web interface or ssh:
$ ssh root@192.168.1.1 cat /dev/mtd11 > huawei_ap5030dn_fw_backup.bin
5. Run sysupgrade using sysupgrade image. OpenWrt
shall boot from flash afterwards.
Return to factory firmware (using firmware upgrade package downloaded from
non-public Huawei website):
1. Start a TFTP server in the directory where
the firmware upgrade package is located
2. Boot to u-boot as described above
3. Install firmware upgrade package and format the config partitions:
> update system FatAP5X30XN_SOMEVERSION.bin
> format_fs
Return to factory firmware (from previously created backup):
1. Copy over the firmware partition backup to /tmp,
for example using scp
2. Use sysupgrade with force to restore the backup:
sysupgrade -F huawei_ap5030dn_fw_backup.bin
3. Boot AP to U-Boot as described above
Quirks and known issues
-----------------------
- On initial power-up, the Huawei-modified bootloader suspends both
ethernet PHYs (it sets the "Power Down" bit in the MII control
register). Unfortunately, at the time of the initial port, the kernel
driver for the B50612E/BCM54612E PHY behind eth0 doesn't have a resume
callback defined which would clear this bit. This makes the PHY unusable
since it remains suspended forever. This is why the backported kernel
patches in this commit are required which add this callback and for
completeness also a suspend callback.
- The stock firmware has a semi dual boot concept where the primary
kernel uses a squashfs as root partition and the secondary kernel uses
an initramfs. This dual boot concept is circumvented on purpose to gain
more flash space and since the stock firmware's flash layout isn't
compatible with mtdsplit.
- The external watchdog's timeout of 1.6s is very hard to satisfy
during bootup. This is why the GPIO15 pin connected to the watchdog input
is configured directly in the LZMA loader to output the CPU_CLK/4 signal
which keeps the watchdog happy until the wdt-gpio kernel driver takes
over. Because it would also take too long to read the whole kernel image
from flash, the uImage header only includes the loader which then reads
the kernel image from flash after GPIO15 is configured.

Flashing instructions:
Depending on the installed firmware, there are vastly different
methods to flash a MR18. These have been documented on:
<https://openwrt.org/toh/meraki/mr18>
Tip:
Use an initramfs from a previous release and then use sysupgrade
to get to the later releases. This is because the initramfs can
no longer be built by the build-bots due to its size (>8 MiB).
Note on that:
Upgrades from AR71XX releases are possible, but they will
require the force sysupgrade option ( -F ).
Please backup your MR18's configuration before starting the
update. The reason here is that a lot of development happend
since AR71XX got removed, so I do advise to use the ( -n )
option for sysupgrade as well. This will cause the device
to drop the old AR71xx configuration and make a new
configurations from scratch.
Note on LEDs:
The LEDs has changed since AR71XX. The white LED is now used during
the boot and when upgrading instead of the green tricolor LED. The
technical reason is that currently the RGB-LED is brought up later
by a userspace daemon.
(added warning note about odm-caldata partition. remove initramfs -
it's too big to be built by the bots. MerakiNAND -> meraki-header.

...and max flash offset
The mtdsplit parser was recently refactored
to allow the kernel to have custom image header magic.
Let's also do this for the lzma-loader
For example:
When implemented together,
this allows the kernel to "appear" to be a rootfs
by OEM software in order to write an image
that is actually kernel + rootfs.
At the same time,
it would boot to openwrt normally
by setting the same magic in DTS.
Both of the variables
have a default value that is unchanged
when not defined in the makefiles
This has no effect on the size of the loader
when lzma compressed.

Import all improvements made in the lzma-loader since development on the
ath79 target started.
This also reverts fe594bf90d ("ath79: fix loader-okli, lzma-loader"), as
is obsoleted by 2ad60168b6af ("ar71xx: lzma-loader: move padding workaround
to gzip step").
Likely, many of the changes should be ported to the ramips lzma-loader as
well, but I don't have a device to test this.

This target aims to replace ar71xx mid-term. The big part that is still
missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik
subtargets will follow.
