hi team：
When I upgraded the program with the 2800155 chip，Online emulation boot area, normal brush，After you jump to the APP area, and then jump to the BOOT area via the app for rewriting, it will trigger Interrupt_illegalOperationHandler (Interrupt_illegalOperationHandler). I check that the boot address before and after the jump is not abnormal. Repeated flushing in the BOOT area will not trigger an exception. As long as I perform a jump command, that is, when I switch from boot-app-boot, an exception will be triggered。
After debugging an online DEBUG breakpoint, I find that the Interrupt_illegalOperationHandler exception is raised when the Fapi_issueProgrammingCommand function is run here. May I ask what caused this? I have no idea at the moment, but I hope you can provide some ideas. Looking forward to your reply, thank you.
