Netgear Stora - Bad blocks

Hello,
just a quick review as said in the very detailed instructions for uboot installation.

Scanning device for bad blocks
Bad eraseblock 785 at 0x06220000
Bad eraseblock 851 at 0x06a60000
Bad eraseblock 864 at 0x06c00000

Bad eraseblock 946 at 0x07640000
Bad eraseblock 947 at 0x07660000
Bad eraseblock 968 at 0x07900000
Bad eraseblock 1063 at 0x084e0000
Bad eraseblock 1159 at 0x090e0000
UBI: number of bad PEBs: 10
UBI: number of PEBs reserved for bad PEB handling: 38


Are those bad blocks out of the mtd0, right? so uboot update could be done without any problem, correct?
What kind of problem could I have with those?

Thanks a lot

I performed the update considering that the blocks where not the one involved in mtd0, but after erasing and writing correctly, fw_setenv seems not to work by ssh console.

@zanco83,

> -bash-3.2# fw_setenv ipaddr 192.168.178.170

That was the stock OS fw_setenv you're using.

Check the content of

cat /etc/fw_env.config

It's best that you post the session how you flash u-boot here.

And do you have serial console? have you tried running kwboot before doing the flashing?

-bash-3.2# cat /etc/fw_env.config
# Configuration file for fw_(printenv/saveenv) utility.
# Up to two entries are valid, in this case the redundant

# Notice, that the "Number of sectors" is ignored on NOR.

I'm trying to set the env variable before booting into usb debian. Do I need to do that after?
I first erase and flash uboot 2017 and then the default 2016 as written in the step by step instructions

Yes, I've serial console
Yes, I tried kwboot through serial but I've received a protocol error

Looks OK.

If you have serial console, then it is OK to set the envs after booting into Debian. The Debian rootfs uses DHCP so the IP address will be assigned by the router. The IP addresses in the envs are only relevant during u-boot booting.

After kwboot starts and see protocol error, up-arrow to recall the kwboot command on the terminal and run it again immediately. Try this many times until you get a handshake. And make sure the 3 serial wires are away from the power cord (it could cause noises).

Hello,
thanks for your answers and your help.
kwboot, request to reboot the device, so it will be with the new mtd.
Can I reboot by netconsole?

> Can I reboot by netconsole?

Don't use netconsole when you have serial console. Serial console willl show everything, netconsole is not good for troubleshooting now. Once you got everything working, you could remove serial console (in this case leave the 3 wires attached for furture debugging).

And then set up netconsole if you wish to see the boot progress, and also recover from a bad kernel installation,....

Thanks Bodhi, everything seems good
