This device is pretty useless with the stock firmware as it requires an
account to completely set it up. Additionally, the vendor bootloader is
signed and uses Airoha/Mediatek's BBT/BMT for bad block management on
the flash. It does not support UBI, thus kernel updates are subject to
BMT/BBT which OpenWrt does not support. In turn, if a kernel update
happens and a block is marked bad in the process, the device will fail
to boot and will need to be recovered via serial.
The workaround is to chainload U-Boot in place of the kernel, as it
should not need frequent updates and thus should not cause BBT/BMT to
misbehave and soft-brick the device. Upstream U-Boot supports loading
a FIT image from UBI, so we create a UBI partition for the new u-boot
env, FIT image and factory data. This way, bad blocks are managed by UBI
instead, which will not soft-brick the device should a block be marked
bad during a normal OpenWrt update. Users wishing to update U-Boot can
do so, but should be prepared to recover if a block goes bad.
Because the device is not useful with stock firmware, this is a one-way
ticket for most users and reverting will not be documented.
The following steps can be used to install OpenWrt on the W1700K.
Connect to serial console. There is a Torx T10 screw underneath the QR
code printed onto the label. Then, pry between the gray and white
plastic, starting by the ports on the back. There are clips arount the
entire device. Starting closest to the screw next to the UART header,
TX - GND - VCC - N/A - RX. The bootloader can be interrupted by
pressing any key.
Configuring Vendor Bootloader and Installing U-Boot Chainloader:
The bootloader's default bootcmd will only run a signed image. However,
we can still bootm our own image from flash.
NOTE: The vendor's ethernet drivers are flaky. You may have to reboot
and try the tftpboot part several times for it to work.
- setenv one flash read 0x600000 0x1000000 \$loadaddr
- setenv two "; bootm"
- setenv bootcmd "$one$two"
- setenv one
- setenv two
- saveenv
- setenv serverip 192.168.1.10; setenv ipaddr 192.168.1.1; tftpboot
0x89000000 openwrt-airoha-an7581-gemtek_w1700k-ubi-chainload-uboot.itb
- flash erase 0x600000 0x100000
- flash write 0x600000 0x100000 0x89000000
- reset
The device will now reboot into the U-Boot chainloader.
Loading the W1700K UBI Installer:
The installer can be downloaded at
https://github.com/hurrian/w1700k-ubi-installer/releases
- Boot the installer via the TFTP option in the U-Boot menu. This
process is automatic, though you may be prompted to answer some
questions.
- Once it is done, you may upgrade to your preferred build.
- For more information: https://github.com/hurrian/w1700k-ubi-installer
For those wishing to explore the stock firmware:
Rooting Stock FW (for making backups, recommended):
- Boot the router and watch serial console until presented with failsafe
mode. Enter it (f + enter).
- mount_root
- Change the root password (passwd).
- Open /etc/config/axon_platform_manager and set sshServerEnable,
localAccessEnable and remoteAccessEnable to 1.
- Search for "SSH". You'll find a long string with 3 matches such as
Enabled%25252c1%25252cSSH%Drop. Change any instances of "Disabled"
preceding SSH to "Enabled" and any instances of "Drop" to "Accept"
that follow SSH. Same for "Local SSH" and "Remote SSH".
- Set /etc/config/dropbear to:
config dropbear
option PasswordAuth 'on'
option RootPasswordAuth 'on'
option Port '22'
- Reboot.
- Connect 10g WAN port to existing network and SSH in with the password
you set.
- SSH into rooted stock fw.

Due to issues surrounding the implementation of the vendor BMT/BBT
on Airoha, upstream ATF + uboot has switched to UBI flash partitions.
However, some devices shipped on this platform are bootloader locked,
and thus it is impossible to replace ATF + uboot.
During testing for the Gemtek W1700K (#17869), sysupgrades from Linux
(which is unaware of the underlying BMT/BBT) would occasionally write
data into blocks which were remapped by the vendor uboot when it was
read on the following reboot, causing a soft brick.
An acceptable workaround [1],[2] was discussed where an intermediate
uboot would be written by the vendor uboot (which is aware of Airoha
BMT/BBT). This chainloader would then ignore the regions of flash
used by the vendor uboot, and store all relevant data inside of UBI.
UBI would then be used to handle bad block management. As the vendor
ATF + uboot do not read or interact with the UBI region, we would avoid
unwanted remaps from BMT/BBT.
This commit introduces support for building such a chainloader, by
packaging u-boot and DTS into a FIT image; to be flashed like a kernel.
Configuration for the Gemtek W1700K is provided as an example of how the
chainloader is used.

Similar to e92b153e99 ("mediatek: introduce KERNEL_LOADADDR to Device/Default template"),
let's move the default loadaddr to Device/Default.
What's more, use 0x80200000 instead of the SDK default value 0x80088000
to avoid the following error which may overwrite TZ memory and cause crash:
[ 0.000000] [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!

Fix the current image Makefile for Airoha AN7583 by dropping the

The artifacts for the bootloader will be readded later once ATF-A
support will be pushed mainline.

This option will only take effect when the "separate_ramdisk"
feature was enabled. However, this target does not support
this feature. It is an obvious copy and paste issue.

Introduce initial support for Airoha AN7583 SoC and add all the required
patch for basic functionality of the SoC.
Airoha AN7583 is based on Airoha EN7581 SoC with some major changes on
the PHY handling and Serdes. It can be see as a lower spec of EN7581
with modern and simplified implementations.
All the patch are sent upstream and are pending revision. Support for
PCIe and USB will come later as soon as DT structure is accepted
upstream.

In preparation for EN7581 SoC support, move en7523 in dedicated
subtarget.
This is needed as EN7581 is now 64bit but en7523 is 32bit hence have
very different kernel config.
Also rename patch to a more friendly number sequence.

Airoha is a new ARM platform based on Cortex-A53 which has recently been
merged into linux-next.
Due to BootROM limitations on this platform, the Cortex-A53 can't run in
Aarch64 mode and code must be compiled for 32-Bit ARM.
This support is based mostly on those linux-next commits backported
for kernel 5.15.
Patches:
1 - platform support = linux-next
2 - clock driver = linux-next
3 - gpio driver = linux-next
4 - linux,usable-memory-range dts support = linux-next
5 - mtd spinand driver
6 - spi driver
7 - pci driver (kconfig only, uses mediatek PCI) = linux-next
Still missing:
- Ethernet driver
- Sysupgrade support
A.t.m there exists one subtarget EN7523 with only one evaluation
board.
The initramfs can be run with the following commands from u-boot:
-
u-boot> setenv bootfile \
openwrt-airoha-airoha_en7523-evb-initramfs-kernel.bin
u-boot> tftpboot
u-boot> bootm 0x81800000
