S32K312 Reset_Handler

LILV — Fri, 13 Feb 2026 07:46:02 GMT

I have a 12V project using the S32K312 chip. However, during the operation, due to the system not being in sleep mode, the battery voltage gradually dropped from 12V to 3V. Then, I tried to charge the battery, but all functions disappeared. Even after a power-off and power-on, the functions did not recover. I try to attach this chip and discovered that the program had stucked in the Reset_Handler step.

What could be the reason for this?

Hi @LILV,

In what loop is it stuck?

Can you share the startup code and the disassembly?

Thank you,

BR, Daniel

Can you show me where is it stuck in the startup?

You should see it in the disassembly.
