nrf_pdm_task_trigger(NRF_PDM_TASK_START) does not work

[neosarchizo]

Hi, now I'm developing my projects with SDK 15.2. and Thingy:52.

The projects are bt-audio-advertiser and bt-audio-receiver.

I adapted extended advertising to a Thingy:52 project, bt-audio-advertiser, successfully. It advertises with 216 bytes manufacture's data and dynamically changes the data each second.

And other Thingy:52 project, bt-audio-receiver, can scan the extended advertisement.

I want to get PDM data of a mic of the Thingy:52 and load the data to the manufacture's data of bt-audio-advertiser.

But Thingy:52 F/W is made of SDK 13. So I migrated legacy nRF drivers including PDM to bt-audio-advertiser.

I can build it, but when I run debug mode, the Thingy stops while running nrf_pdm_task_trigger(NRF_PDM_TASK_START) in nrf_drv_pdm_start function of nrf_drv_pdm.c.

Following image is when the Thingy stops.

I also uploaded my projects in Dropbox.

I can't debug deeper than nrf_pdm_task_trigger(NRF_PDM_TASK_START).

What's the cause of that?

Hi Neo,

From your screenshot there seem to be that you are missing some "debugging" steps since there isn't that much information.

Could you make sure you followed the correct measures regarding Debugging in SEGGER IDE?

Thanks! The video was very helpful.

I was able to find the cause of the problem.

I missed following things.

• Add APP_SCHED_INIT, app_sched_execute in main.c
• Change H/W version of Thingy to THINGY_HW_v1_0_1 (my thingy version)
