RM57L843: HAL Code Generator: WATCHDOG2_RESET in resetSource_t

Part Number: RM57L843

Hello,

The code generated by the HAL Code Generator tool creates the resetSource_t enumerator (HL_system.h file) with WATCHDOG2_RESET that refers to a bit that is reserved in the System Exception Status Register (SYSESR).

WATCHDOG2_RESET is used in _c_int00().

Does WATCHDOG2_RESET has a meaning? Can it be removed from _c_int00()?

Best regards,

Marcio.

Hi Marchio,

I am suspecting this resetSource_t structure is designed for dual core even though they are always operated in lock step mode, just like as mentioned in below thread:

(+) RM57: Questions about HL_system.c getResetSource() - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

I practically created watchdog reset and found that only "WATCHDOG_RESET" bit got SET and "WATCHDOG2_RESET" not SET after RESET.

So, TRM is correct and HL_system.h needs to be correct.

Thanks for pointing out this issue and we will take necessary corrective action on this issue.

Thanks & Regards,
Jagadish.
