My AR-300m (“Shadow”) can read its U-Boot environment from Linux with the fw_printenv command after I set the /etc/fw_env.config to:
/dev/mtd1 0 0x10000
However, I cannot find any information on the proper fw_conf.config for the AR750S (“Slate”)
Warning: Bad CRC, using default environment
Has any managed to get this working?
shows the dev paritition is erased to All 0xff’s
whereas on the Shadow, it contains the env variables.
Both units /proc/mtd indicate that the u-boot-env should be
/dev/mtd: 00010000 00010000 “u-boot-env”
Both routers are running 19.07.7 from NAND flash
Is the /dev/mtd1 partition usually erased?!
