[CC2652R RCP] OTBR crashes when trying to add a device

[samuliHeikkinen]

Hello!

To start of massive thank you, for the work you've done!

There is something funny with the RCP firmware for CC2652R. I can setup OTBR completely fine and get a Thread network running and all is good on HA side as well, but once I try to add a device to the network, otbr-agent fails panics and shuts down. Any ideas?

After the crash the dongle needs to be plugged in again. Nothing else works.

Hi, looks like I have the exact same problem, have you found a solution?
I have CC2652P and tried both CC1352P2_CC2652P_other_ot_rcp_2025_3_1_20250313 and CC1352P2_CC2652P_launchpad_ot_rcp_2025_3_1_20250313 firmwares - both boot but cant finish pairing.

My god, I was able to make it work. There is a bug in the firmware. Check the diff.

Makes me question a lot of things.. but anyways.

I have updated the OpenThread submodule for a good measure, and everything seems to work. I am attaching rebuilt HEX files to this comment so you can test it right away.

I was able to connect my IKEA sensor to HA after.
