Hi, I am trying to use RTX on my target(LH7A404). I refered to the example and wrote my own startup.s. But I found in the example that the assembly jump to __main finally. And when I download my image to my target, there would be something wrong. When machine ran into __main block, it would execute a code(SWI 0x123456) and it crashed. Could anyone tell me what the purpose of the __main block is? Is there any configuration I miss in my code? Thank you.
