RTOS/CC2652R: Crash while switching to External Oscillator in ISR

Sanjay

Part Number: CC2652R

Tool/software: TI-RTOS

Hi,

I have simple peripheral example-based binary that was running fine on one of my custom-boards, but is crashing on another. The function in which the hard fault is caused, is NOROM_OSCHF_AttemptToSwitchToXosc() which is called in an Oscillator ISR.

Just trying to isolate the issue to see if it's an issue in my board.

It sounds like the 48 MHz xtal is not starting. Could you share the part of the schematic that covers the xtals and also provide a close-up of the board where the xtals are mounted.

I was able to use this board after flashing it with a different firmware image, and then flashing it again with the original firmware image.

It seems like my firmware image was probably not clearing something in the CCFG region by default.. Will report once I root-cause the issue.
