[LEDE-DEV] [PATCH v3 1/2] ar71xx: Add support for TP-Link MR6400

[Filip Moc]

Hi Piotr,


> Is there any problem with upgrade under vendor gui on this device?

Yes, web-ui rejects factory firmware with the following message:
-
Error code: 18005
Upgrade unsuccessfully because the version of the upgraded file was incorrect.
Please check the file name.
-

If you unpack any firmware provided by TP-Link[1] you can see there is ~50MiB
.bin file. This file contains not just firmware for main SoC (QCA9531) but
there is also firmware for embedded LTE module.
I guess OEM web-ui won't accept firmware without this attached firmware.

But flashing via U-Boot's TFTP recovery seems to be safe. It checks for product
id and won't let you flash wrong firmware. Also U-Boot does not overwrite
itself during the process so even if you brick the device (e.g. due to power
loss) you can retry as many times as you need.

Ok, I'll resend 1/2 with updated commit message.
