hello,

i'm using S32R294 and Mcal version1.0.1

while running the step of "REG_WRITE32( (*PLLDIG_pConfigPtr->apPllDigConfig)[u32Counter].u32RegisterAddr, (*PLLDIG_pConfigPtr->apPllDigConfig)[u32Counter].u32RegisterData );" connected Lauterbach,the code will crash.

if i disconnect Lauterbach, it will work well.

for more information please check the snapshot below.

do you know the root cause?

Hello,

Are you doing step debugging while it crash?

When you execute it by F4 (step over) it fails?

It looks to me like some timing protection which runs out if you execute the code in steps.

Best regards,

Hi,

this issue has been fixed, which is caused by the clock configuration, as I set the run0-3 in CCTL2/CCTL3 to CLK_GATED, the problem will raise.
