TL-WPA8630P V2 Boot loop after sysupgrade

Ah brilliant. If you are able to get the recovery http server, you should be able to upload the stock TP-Link firmware (.bin file from TP-Link firmware .zip), and that should get the device back working.

The http server might also be startable using the command "httpd" according to the u-boot sources in the TP-Link GPL code. You can try "setenv ipaddr" to set the IP.

I would avoid any u-boot flash erase guesswork if possible unless your 100% sure. Others tried it and wiped their bootloader, forcing them to SPI flash instead.
