USBD BLE UART Freertos example restarts on USBD with nrf52 module

[Ali Rumane]

Hi,

I am trying USBD BLE UART Freertos example on Laird’s BL654 module, the application keeps on restarting when I open USB COM Port and works fine for BLE UART.

I changed NRF_LOG_BACKEND from UART to RTT as in default example and SoftDevice clock configuration as per module settings.

I also included DEBUG in preprocessor symbols to see if I can see any known issue on log but I am unable to find one.

I tried USB CDC ACM example and it works as expected.

Below is an image for reference.

Hi,

Please try to read the POWER.RESETREAS register on startup to see what the reset source is. Also, do you see the same issue if you run it on a DK or use the USBD example without freertos?

Hi,

I don't know how but it is working fine now.

If same thing happens, I will read  POWER.RESETREAS register and will let you know about it.

Thank you for your help.
