I have a problem installing OpenWRT WavLink AC600 WL-WN570HA1. It is on the compatibility list but unfortunately another FLASH memory 64Mb was installed - BoyaMicro 25Q64ASSIG. As a result, partitions are not detected and cannot be written to. After connecting RS232 kernel startup message " spi-mt7621 10000b00.spi: sys_freq: 193333333
[ 7.481521] spi-nor spi0.0: unrecognized JEDEC id bytes: 68 40 17 68 40 17
[ 7.495264] spi-nor: probe of spi0.0 failed with error -2". This causes the device to fail to flash and resets in a loop. Unfortunately, I don't have enough knowledge yet to be able to make a patch myself.
