Bad block on Goflex net Nand

Hello,
I want to install Openwrt in my Goflex Net, I check Uboot with Kwboot-tool and this is the output:


U-Boot 2016.05-tld-1 (Jun 12 2016 - 13:27:19 -0700)

Is it all ok or there are any problem?

Then I check the Nand block memory and I have this answer:

[ 1.140000] Bad eraseblock 1431 at 0x0b2e0000

Can I proceed with the boot upgrade or is there a serious problem ?

Thank you, and sorry for my bad English

That bad block is in different area in NAND. You can install u-boot without worry.

Hello,
I want to install Openwrt in my Goflex Net, on the terminal output after booting, I have had the following lines:

Can I proceed with the boot upgrade or is there a serious problem ?

Many thanks for your help

All your bad blocks are at 71MB or above in the "data" region. Should be OK. Just pay attention to OpenWrt installation procedure to see how much memory the current installation needs (I recall that it needs a lot less than that).

@bodhi
Many thanks,
can I ask if the "Update uBoot on your Dockstar, GoFlex, or Pogoplug NAS"
is always valid for boot upgrade of my GFN .
Thanks.
