I have debuged the application with visual X-tools debugger on the 7520 Board. It need to modify the .ini file. But I still have some questions.I can’t debug the .s file. In the ComboBox ,there is only the *.c files no *.s files. And I can’t not read the register in the cpu.Such as the SCR,MCR…
because of the limitation of gcc/gdb you cannot see assembler source code in the gdb/insight. however you can put a breakpoints there and debug it. for exeample b Reset_Handler_ROM will place a break point at the entry of init.s SCR & MMCR are memory mapped registers (0xffb00000 & 0xffc00000) so you should be able to access them as a regular memory locations
