But when we tried to erase using the flash_eraseall command, we are getting the below log
root@atc-gen2:~# flash_eraseall /dev/mtd0
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it

We need to know whether our changes are proper for 2 NOR flash chips and also we need solutions to our flash_erase error.
