Platform

cc13x2_cc26x2

Anything else?

jmarkel@ILA1LT7WDN593:~/connectedhomeip/examples/pump-controller-app/cc13x2x7_26x2x7$ pip install intelhex
Requirement already satisfied: intelhex in /home/jmarkel/connectedhomeip/.environment/pigweed-venv/lib/python3.8/site-packages (2.3.0)

jmarkel@ILA1LT7WDN593:~/connectedhomeip/examples/lock-app/cc13x2x7_26x2x7$ pip list | grep intel
**intelhex                      2.3.0**

Interestingly, checking out a prior commit and building will work, as will switch back to the original/master (if the out/debug directory remains intact):

I worked through this with @ReneJosefsen yesterday. He suggested the following workaround, which was successful:

As a workaround, it seems like you can add:
intelhex
to connectedhomeip/scripts/setup/requirements.ti.txt and then add
pw_build_PIP_REQUIREMENTS += [ "${chip_root}/scripts/setup/requirements.ti.txt" ]
to connectedhomeip/examples/lock-app/cc13x2x7_26x2x7/.gn, just below import("//args.gni")

Also, please query TI for when the CC26x2x7 builds will be enabled again in the workflows.

#26955

[ReneJosefsen]

We should find a way to get this added to the TI platform in a way that is get applied for all applicable examples. The above is mainly to get unblocked. Given this is related to OTA it could also be worth to only require these modules if OTA is enabled.

[ReneJosefsen]

Given the mentioned PR have merged, I would assume this issue is ok to close.

[Alami-Amine]

it looks like the issue was resolved
additionally, we are now supporting cc13x4_26x4 instead of cc13x2_26x2, I assume we can close this
