Hi!
I have the following problem: I’m unable to communicate to U-Boot through serial.
My u-boot-env
is the following:
root@OpenWrt:~# fw_printenv
lf=if ping $serverip; then tftp 0x80060000 $firmware_name && erase $firmware_addr +$filesize && cp.b $fileaddr $firmware

I use 115200 8N1
for minicom
but it still doesn’t work, as seen below. (SNIPPED the middle.)
