AP152 & TP-Link Archer C7

[Brice GIBOUDEAU]

?Hello,


As I need to modify the boot environment I need to upgrade the fairly old Uboot-1.1.4 that you find on those quite popular device TP-Link Archer C7 (version 5 in my case).

After investigations I found that you have a support for the AP152 that is the base of that router. I just changed few things to enable the proper boot address and Ethernet support.


U-Boot work well but twhen OpenWRT boot it crash with random characters on the console during the PIEe initialization.


Did I missed something ? (a variabe to set somewhere ?) I added debug info below.

Below the last line of the boot log from the console that show the issue.

---------

My U-Boot version: U-Boot 2022.04-rc4 (Mar 15 2022 - 16:56:25 +0100)

---------

I cross compiled it with the OpenWRT SDK: openwrt-sdk-21.02.2-ath79-generic_gcc-8.4.0_musl.Linux-x86_64

--------

I'm booting OpenWRT 21.02.2 and it boot correctly with the original U-Boot that I recovered a couple of time to investigate.
