I tried to compile the LPCUSBLib example projects, which failed for the LPC4357 on the MCB4300 board. It wouldn't compile because of not enough RAM, so I set IRAM1 size to 0xC000. Now it compiles and downloads to the board.
When I try to debug it, I cannot enter the main() function. It appears it's stuck in the systemInit() function:
void SystemInit(void)
{
#if defined(CORE_M3) || defined(CORE_M4)
unsigned int *pSCB_VTOR = (unsigned int *) 0xE000ED08;
*pSCB_VTOR = (unsigned int) &__Vectors;
#endif
}
Once I try to step over this line,
unsigned int *pSCB_VTOR = (unsigned int *) 0xE000ED08;
the debugger enters a hardfault, and the command window states "cannot access memory"
My guess is the address 0xE000ED08 is out of bounds, but other projects with the same systeminit runs fine. Perhaps I should lower the RAM size? But then the program won't compile.
Does anyone have any ideas to solve this?
