Updated uboot from 2014- Cannot scan pogoplug v4 on network
March 23, 2021 04:05PM
Hi,
Having issues with updating from the 2013 roots to the latest version. I attempted to update uboot to the 2017 version, but I believe I messed something up. Can someone with a little better knowledge let me know if I need to crack it open?
I can boot the old rootfs from 2013 and the led goes green, but is not present on my network. I don't see a mac address, would this be an issue?

Yes, it would be. The green LED indicated that you have booted the kernel. But the Ethernet connection probably was not active.

To fix this temporarily, use uEnv.txt method.

Refer back to when you download the envs image in u-boot installation thread:

8. Flashing default u-boot envs image (if you are upgrading from 2016.05-tld-1 u-boot, you can skip this step 8).
.....
.....
a. Download the default u-boot envs at Dropbox:

uboot.2016.05-tld-1.environment.bodhi.tar
md5:
3823eef10011b864859d31a76470e0e3
sha256:
c8db95a4225e8d78bdaaaa372bd5a87e4b98f3448dd9c62fc96c72b2df1a997c

This tarball includes 3 files:

uboot.2016.05-tld-1.environment.img (the default envs image to be flashed)
uboot.2016.05-tld-1.environment (the content of the default envs in text format)
uboot.2016.05-tld-1.environment.64K.img (small envs image to be flashed on HP T5325 only).

The file uboot.2016.05-tld-1.environment is the envs listing that I used in creating the uboot.2016.05-tld-1.environment.img. This can be used as uEnv.txt.

Moun your rootfs on another Linux box. Copy the uboot.2016.05-tld-1.environment to the rootfs. Assuming it is mounted at /media/sdb1.

cd /media/sdb1/boot
cp -a uboot.2016.05-tld-1.environment uEnv.txt
And then adjust one env in this file.

Look for the env
dtb_file=/boot/dts/kirkwood-pogo_e02.dtb

Replace that with
dtb_file=/boot/dts/kirkwood-pogoplug_v4.dtb

That's it. The MAC address is default to a local MAC address in the default envs uboot.2016.05-tld-1.environment. You could also change it to the real one the same way you change the DTB name above. Look for MAC address on the box label outside the case.

The default local MAC address should work, if there is no other Kirkwood box running in the network that was installed with same u-boot. If there is, the MAC address should be modifed to have the real value for this specific box.

Save the file and sync
sync
And unmount.

Take it to the Pogo V4 and boot.

After you've booted into Debian, log in and add the MAC address with fw_setenv

fw_setenv ethaddr xxxxxxxx
where the xxxxxxxx is the real MAC address.

That is great news. Will get it up tomorrow.
Glad to hear it is something simple. Was beginning to pull my hair out.
Thanks again for the focus on the issue. Will post my success later to confirm.

Thanks again. Had a raspberry pi I was able to use to update my usb. Inserted the modified uEnv.txt in my boot did and got it working real quickly. Netconsole is working also..
All is well!
