Thanks for the output, I'll browse through and see if I can spot a light at the end of the tunnell.
By the way, I meant the command altogether, i.e:
run mtd -r erase rootfs_data
yes did a long time ago:
Easy-Link> run mtd -r erase rootfs_data
## Error: "mtd" not defined
Easy-Link>
Edit: Really appreciate your help. or Elf-lp ;-)
