Thanks for your prompt reply. I already tried that but it won't
boot for me. Maybe additional info related to barebox env needs to be
written.
I am trying by sending UTP commands from MFGtools:
UTP: received command '$ flash_erase /dev/mtd0 0 0'
UTP: executing "flash_erase /dev/mtd0 0 0"
Erasing 128 Kibyte @ 39002e0000 -- -1 % compl[ 6.275463] utp_poll:
pass returned.

UTP: sending Success to kernel for command $ nandwrite -p /dev/mtd0 -p $FILE.

I am writing a barebox.bin using nandwrite but it seems the new
barebox(which is correct should boot) won't boot. So I am wondering if
the nandwrite command is enough?
I know nandwrite you can use it successfully for flashing roots or
kernel on mtd partition but maybe for the bootloader is not working
Thanks,
