PDM start fail

[Louis Wnag]

Hi, I'm using the nRF52840 SDK15.2.0
I'd like to get data from a digital microphone via a PDM interface. The teansfer data to speaker via a I2S interface.

Here is my problem:

In the ret_code_t nrf_drv_pdm_start(void)
{
...

nrf_pdm_task_trigger(NRF_PDM_TASK_START);
NRF_LOG_INFO("PDM TASKS START\r\n");
...
}

I can't see information "PDM TASKS START"

If I use
nrf_pdm_task_trigger(NRF_PDM_TASK_STOP);
NRF_LOG_INFO("PDM TASKS STOP\r\n");
I can see information "PDM TASKS STOP"

Thank you.

Ok. But have you figured out which line is causing the error?
