Regression in Kernel 4.19

[amilcarlucas]

I'm running the rcn-ee.net Ubuntu Console Image 2020-04-09 and it does not auto-detect my three capes:

• BBORG_COMMS-00A2
• BBORG_PROTO-00A2
• BBORG_RELAY-00A2

I am running an older image in another board and it works fine there:

On this Other board (using the same capes) I get:

To try and solve this I did:

sudo apt update
sudo apt upgrade
cd /opt/scripts/tools
git pull
sudo ./update_kernel.sh --lts-4_19 --ti-channel
cd /opt/source/bb.org-overlays/
git pull
make
sudo make install

But still I get noting when I do:

cat /proc/cmdline | sed 's/ /\n/g' | grep uboot_detected_capes= || true

Why does it work fine in the older 4.14 board, and fails in the fully updated 4.19 board?

[amilcarlucas]

It looks like i2c-2 is not working at all :( and that causes the capes to not be detected. Could this be caused by https://github.com/RobertCNelson/Bootloader-Builder/commit/294bc183dfa64c09ac4a83ba66c1e8dc74b922d9 ?

[amilcarlucas]

You seam to have added i2c permissions on Nov5 but that has not fixed the problem :(
