Bootloader jump to APP

Hi,

 

I'm working on FBL development based on S32K142, and I've programmed the app code into flash by FBL successfully, but after boot, I can't start app because it will get stuck in WDOG_EWM_IRQHandler(); as the following picture.

I put the jump function at the begin of FBL code, it can jump to app, so I think the jump function is correct. But if I put the jump function after SBC_Init(), it can't jump to app. It seems that SBC will effect the jump function. What should I do before jump from boot to app except disable all interrupts? Is there any special operation for SBC?

 

Best regards,

Sarah
