A HAL_RCC_OscConfig problem in mbed-os 6.12


I had remove the extern XTAL from the NCULEO-L432KC.
And below is my mbed_app.json (To use internal 16MHz XTAL):

    "target_overrides": {
        "NUCLEO_L432KC": {
            "target.clock_source": "USE_PLL_HSI"

mbed-os 5.14 : work fine.
mbed-os 6.12 : show a run-time error as below:

Sorry, I need help …

Best Regards,

I got a solution .
If disable the tickless feature, the internal XTAL will work fine.

"target.macros_remove": ["MBED_TICKLESS"]

Also have to remove all platform stats features from mbed_app.json:

  "platform.stack-stats-enabled*": true,
  "platform.heap-stats-enabled*": true,
  "platform.cpu-stats-enabled": true,
  "platform.thread-stats-enabled": true,
  "platform.sys-stats-enabled": true,

Is a bug in the mbed-os 6.12 ?
