    I tried to solder SD/MMC card onto a board, compiled a driver for openwrt rc5 and put a card into. Then the board failed (firmware was corrupted) i attached jtag flashed new CFE then when it was answering for tftp on all ports i put new firmware using either serial console and just tftping after enabling boot_wait. So problem appears that after successful flashing it has broken switch chip i guess cause i soldered mmc pin to a RP3 near ADMTek chip (maybe overheated it cause it looks not as good). When i use serial console it cannot recieve any packets from the any ethernet. It can send requests for dhcp lease on wan side. Also the lights came like there was no vlans made, but i have checked plenty of times and all is ok cause finally i flashed orginal linksys firmware into that rebuild my nvram completely as it should be.
    Does anybody has detailed spec for this board especially showing what this RP3 chip is. It has a number 620 on it and is the same as RP2 has 8 pins. I went trought a long way to debirck it and replacing this silicon is my last attempt.
