NSA325V2 u-boot installation - Problem with permission denied (1 reply)

Hello!

I'm trying to install the newest U-Boot 2016.05.

Part "A. Flashing Instruction:" doesn't work for me ("flash_erase /dev/mtd0 0 4" results in an error message). A little bit of googling got me to a page on this forum stating, that my NSA325v2 is using stock boot environment parameter and I've to update them by using the update procedure described in section "B. Flashing default u-boot envs image"

Nevertheless, this doesn't work either, "/usr/sbin/flash_erase /dev/mtd0 0xc0000 1" gives me

root@debian:/media/test/envs# /usr/sbin/flash_erase /dev/mtd0 0xc0000 1
flash_erase: error!: /dev/mtd0
             error 13 (Permission denied)

Any suggestions?

Maybe the following information can help you in finding the problem?
