Problem booting Pogo v4

kwboot is how it is booting. If I don't use it the pogo doesn't boot.

strix@atlas-2:~/kwboot/kwboot-tool$ sudo ./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2016.05-tld-1.pogo_v4.mtd0.kwb -p

I'm guessing I messed up flashing u-boot which is why it won't boot on it's own?
Do I need to try installing/flashing uboot again?

Ah. I see. That's why your u-boot envs look good when running kwboot. The envs were populated correctly.

OK. Then the next step is booting into Debian and reflash only u-boot image. No need to go through entire precedure. kwboot again like before. And log in as root.

1. Verify mtd layout

cat /proc/mtd

Expected output:

dev:    size   erasesize  name
mtd0: 00200000 00020000 "u-boot"
mtd1: 00300000 00020000 "uImage"
mtd2: 00300000 00020000 "uImage2"
mtd3: 00800000 00020000 "failsafe"
mtd4: 07000000 00020000 "root"

2. Erase 4 blocks on mtd0

flash_erase /dev/mtd0 0 4

Expected output:

Erase Total 4 Units 
Performing Flash Erase of length 131072 at offset 0x60000 done

3. Flash u-boot image

nandwrite /dev/mtd0 uboot.2016.05-tld-1.pogo_v4.mtd0.kwb

Expected output:

Writing data to block 0 at offset 0x0 
Writing data to block 1 at offset 0x20000 
Writing data to block 2 at offset 0x40000 
Writing data to block 3 at offset 0x60000

And then reboot. This time, only connect a normal serial console running putty/picocom/screen. Watch the serial console output for any thing abnormal (if not sure, post the serial console log here).

I get this error when I try to flash_erase

root@mnemosyne:~# flash_erase /dev/mtd0 0 4
flash_erase: error!: /dev/mtd0
             error 13 (Permission denied)

Strix,

Perhaps something is different about the Pogo V4 in the later kernels.

cat /proc/cmdline
cat /proc/mtd
ls -l  /proc/device-tree/mbus\@f1000000/nand\@012f/partition\@0/
ls -l /boot/dts/kirkwood-pogoplug_v4.dtb

If my guess is right, I'll recompile a new DTB for you to try it.

Strix,

cd /boot/dts
mv kirkwood-pogoplug_v4.dtb kirkwood-pogoplug_v4.dtb.old

Dowload this attached DTB file and put it in this /boot/dts folder.

wget http://forum.doozan.com/file.php?2,file=1246,filename=kirkwood-pogoplug_v4.dtb

And then

sync

and reboot.

New dtb allowed me to flash uboot

Seems like everything is good now. Pogo is booting normally.

Was there a problem with the dtb file I was using?
Is there anything I should keep in mind for future upgrades?

Thanks for testing Strix! Good to see it's working.

No, it's apparently a change in the way the DTB is loaded in the newer kernel driver (So it seems).

Keep this version for use in the kernel 4.9 if you upgrade. I will need to release updated DTBs for boxes that are affected.

Awesome, glad I was able to help out.

Thanks for walking me through all this.

Hi Strix,

> Awesome, glad I was able to help out.

Indeed, users have reported this similar problem but I thought it was something else. Live testing with serial console log has made it more apparent for me to understand the cause.
