CONFIG_NET_L2_OPENTHREAD=y leads to failure in gpio pins.

Hi,

I noticed an issue with CONFIG_NET_L2_OPENTHREAD=y in my project, and I prepared a newer, simpler project to investigate in the issue.

The new program simply sets pins to high and low. After flashing it onto an external module and plugging the external module onto a baseboard, all of the LEDs on the base board should be flashing one by one in a cycle..

As I slowly add more configurations to prj.conf, I realize that adding CONFIG_NET_L2_OPENTHREAD=y when CONFIG_NETWORKING=y will lead to all the external module pins behaving unexpectedly. None of the LEDs on the base board will turn on. What does CONFIG_NET_L2_OPENTHREAD do exactly? How does it interfere with the gpio pins?

    err = mpsl_init(&clock_cfg, CONFIG_MPSL_LOW_PRIO_IRQN, m_assert_handler);

    Are you able to see what the return value from mpsl_init is? Is it an error (-NRF_EPERM or -NRF_EINVAL) or a success code?

    Are you able to tell anything from this? Please update me on it if you have time to take a look at this, thanks!

    Other than finding out the return code I can't tell much from this no.

    I'll be able to get some debugging tips early next week!

    Could there be an issue with how the hardware of my external module was designed?

    Maybe. Is your module a commercially available one or is it custom to you and not yet on the market?

    If it is custom -- and you haven't done the following before -- we offer hardware reviews here on DevZone. Just post your schematics/layout files in a new private ticket and then one of our hardware engineers can review them.

    Best regards,
