OT-cc2538 as RCP fails because of missing capabilities: tx-security tx-timing

[Gunzter]

I was trying to use the ot-cc2538 ot-rcp together with the ot-docker image.
I built commit 08e58f0 with commands:
./script/bootstrap
./script/build
arm-none-eabi-objcopy -O binary build/bin/ot-rcp build/bin/ot-rcp.bin
python3 $HOME/workspace/cc2538-bsl/cc2538-bsl.py -e -w -v -p "/dev/ttyACM0" -a 0x00200000 build/bin/ot-rcp.bin

Then I start the docker image with:
`docker run --sysctl "net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1" -p 8080:80 --dns=127.0.0.1 -it --volume /dev/ttyACM0:/dev/ttyACM0 --privileged openthread/otbr --radio-url spinel+hdlc+uart:///dev/ttyACM0'

As I have seen from other OT issues and questions on mailing lists, there seem to be an upgrade of the Thread Protocol version to 1.2, is that the culprit here also?

@Gunzter , yes, we do not currently have required Thread 1.2 features supported on the CC2538.

To use OTBR in Thread 1.1 mode you try adding the following line to third_party/openthread/CMakeLists.txt

set(OT_THREAD_VERSION 1.1 CACHE STRING "Thread 1.1" FORCE)

Then make sure to set BACKBONE_ROUTER=0 when invoking ./script/setup

BACKBONE_ROUTER=0 ./script/setup

Hope that helps.

[Gunzter]

Hi,
I added: set(OT_THREAD_VERSION 1.1 CACHE STRING "Thread 1.1" FORCE) to line 40 of third_party/openthread/CMakeLists.txt

I also changed line 89 in etc/docker/Dockerfile from && ./script/setup \ to && BACKBONE_ROUTER=0 ./script/setup \

That solved the problem! Thank you!

I will close the issue.

For some reason I'm trying to do the same thing (made the same changes as you @Gunzter), but I still see prints of both OPENTHREAD_CONFIG_THREAD_VERSION=OT_THREAD_VERSION_1_2 and OPENTHREAD_CONFIG_BACKBONE_ROUTER_ENABLE=1 while building

Update: it worked after deleting the whole CMake build folder @jwhui
