I want to send serial number to dhcp server.
It is ok to read serial number from eeprom in linux: cat /proc/device-tree/serial-number
I can also do it in uboot interactive console:
fdt addr $fdt_addr
fdt get value serialnum / serial-number
Problem with this approach is that sometimes some kind of race appears and uboot hangs.
Can I know, why nvidias uboot doesn’t set standard serial# environment variable?
