Hello Bodhi,

I am trying to get my old NSA320 back into shape and wanted to install debian kirkwood on it.
After setting up an UART session I probed with UART booting - all went well.
However, when trying to prepare it for flashing u-boot, I found bad blocks (step 4).
I wanted to get your opinion and see if there's a way or if it's safe at all to flash u-boot on my NSA320.

Here's what bad blocks have been found:

/ # dmesg | grep -i 'bad'
Scanning device for bad blocks
Bad eraseblock 32 at 0x000000400000
Bad eraseblock 249 at 0x000001f20000
Bad eraseblock 802 at 0x000006440000
Bad eraseblock 973 at 0x0000079a0000
block 13 is bad

ZVPalu,

That's OK. The bad blocks are away from u-boot region (block 0 to 7). Those are far in the NAND flash. It is safe to flash u-boot.
