Device : S32K148 EVB,
Environment S32KDS 2.2
Issue : Post build, generated Hex is extended to fill the required size of the allocated flash for the code section and updated with CRC code at last. But when this generated hex is used to flash, flashing seems to be successful, but immediately debugging is not possible. Can you let me know the issue here?
Below is the log from console during flashing/debugging:
Connection from "127.0.0.1" via 127.0.0.1. Connection from port "50876" to 6224
Connection from "127.0.0.1" via 127.0.0.1. Connection from port "50878" to 7224

Task name prints(junk) are continuous on the console output. Once the target is power reset, I am able to debug without loading flash, and device seems to executing the right code. Why doesn't the debugging work right away after flashing as in the generated hex/elf flashing case?
Debug/Flash Configuration settings:
Attached are the build generated hex and extended hex files.
Hello,
I suspect the problem in the debug session is caused by the fact the debugger set the PC to address 0x0 (see below). Typically this address is used for interrupt vector table and not for the application entry point. After reset PC is set to the reset vector and it works fine.
I'd suggest to untick "set PC..." option and re-try again.
Hope it helps.
