If we do: $ ifup eth0 $ ifdown eth0 and then: $ ifup eth0 $ ping HOST_IP the device hangs and can only be saved by resetting the board manually. We narrowed the problem down to the "fec_tx_task_enable". It seems that enabling tx task with writing to TDAR reg hangs the device shortly after. Did you guys maybe encounter something similar on i.MX6 boards or on any other boards? I guess this is a really specific problem as people don't normally do ifup/ifdown with ethernet in bootloader :D. Do you have any idea what could be the reason or how could this be solved? Any useful information would be greatly appreciated. Using barebox v2022.02.
