I first did all the run update correctly through a working tftp server (run update_uboot, run update_dtb, run update_kernel and run update_rootfs). Then, when I restarted the board, it was impossible to obtain files from tftp server. I can ping from my computer to my virtual machin but not from my board to my virtual machin. When I print the environement (printenv), the first line indicates: addipargs=setenv bootargs ${bootargs} p=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:eth0:off Moreover, the led on the swith and on the board for ethernet is not turned on. When I try run update_dtb for example, I have the following message: FEC: Autonegotiation timeout Using FEC device TFTP from server 192.168.1.38; our IP address is 192.168.1.246 Filename 'apf27.dtb'. Load address: 0xa000000 Loading: * ARP Retry count exceeded; starting again I tried with three different APF27 board that were working previously. Therefore, it seems that it is a problem of the u-boot or a configuration done later that turns off ethernet. Does someone have any idea to solve this problem?
