Unable to upgrade to 2.1.0

[Slyrc]

I have a Turing Pi 2.4 which is currently running 2.0.5

If I upgrade over ota to 2.1.0 the whole software bricks and interestingly shows version 1.0.0 on the website.
After that basically it is useless. I can not connect via ssh anymore.

I also flashed an SD card with 2.1.0 -> Same result here as well. Stuck and won't go anywhere. Only difference here is that I can not even open the webpage.

Only thing worked for me was using an SD card with 2.0.5 again to go back.

Also LED at node 1 is constantly flashing. Not sure if this was here before?

Some more input here:

Here is the output of 2.0.5 starting (Even if there are some errors it still starts and I can login over ssh and the web ui)

This utility will perform a fresh installation of the Turing Pi 2 BMC firmware.

Note that this will ERASE ALL USER DATA stored on the Turing Pi 2 BMC, thus
restoring back to factory defaults. Do NOT proceed unless you have first backed
up any files that you care about!

If you wish to confirm the operation and proceed, either:
1) Type 'CONFIRM' at the below prompt
2) Press one of the front panel buttons (POWER or RESET), or the KEY1 button on
   the Turing Pi 2 board itself, three times in a row

If you are here in error, please remove the microSD card from the Turing Pi 2
board and reset the BMC.

After reboot with 2.1.0 I am able to login over uart. Seems like it does not get an IP address which is the case with 2.0.5 but not with 2.1.0

[svenrademakers]

It seems like you have some hardware issues; more specifically I2C-0 bus seems to be unresponsive. This part of the hardware got enabled on v2.1.0 so it explains why downgrading to 2.0.5 works. I would chech if you can reach out to turingpi on their website and see if they can do anything for you

[svenrademakers]

do you have any usb cables attached to the board? its worth a shot to completely take of the power off the board with all peripherals detached.

[Slyrc]

Good to know. I will try to reach out to them. Thanks!

[Slyrc]

Well I removed everything from the board including the battery. Waited a few minutes and the tried again. Seems like I am not lucky here.

[Slyrc]

Do you maybe know where this part is located on the board? Maybe it can be checked and repaired/replaced?
