Processor expert has linker options in cpu build options. There is a dropdown that lets you specify default interrupt locations in internal flash, external flash, internal ram or external ram. The internal flash option is default and works correctly. If you change that dropdown from internal flash to internal ram, it changes the m_interrupts section to start at 0x1fff0000. I have to setup the debugger to jump to 0x410 to start, but it breaks after the first pop because the stack pointer is not correctly setup. Am I doing something wrong or could this be a bug?
