Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

I don't think the issue mentioned in https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/916063/tms570lc4357-data-abort-exception-after-software-reset is fixed in HALCOGEN yet. I still see dabort in SCI after SOFTWARE RESET.

Can you please post the details of your issue and your application?

My issue is same as described in the post https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/916063/tms570lc4357-data-abort-exception-after-software-reset

After invoking software reset, I was getting a data abort at ``` sciREG1->GCR1 |= 0x80U;``` in sciInit() of HL_sci.c

Does my workaround not work for your case?

Does data abort happen at the same address (sciREG1->GCR1 |= 0x80U;) for every SW reset?

The workaround did help. My post was more about the update to Halcogen
