S12Z boot jump

L_lh — Tue, 14 Nov 2023 02:15:22 GMT

Debugging the boot of S12Z, but there was a problem with the boot redirecting to the app and it couldn't be redirected. Can you help me check the problem. My steps: 1. Boot burn address 0xFFC000-0xFFFDFF 2. APP burning address 0xFE0200-0xFFBFFF 3. The program runs in the boot to enable CAN_ IBS_ Control. u8con=2 to execute the jump app operation 4. The resulting program does not jump and runs directly into while (1) The attachment contains some code for the APP and boot project, and I have removed some other unrelated code

Hi,

I'd like to suggest you to compare the code with this one....
