kind of works for writing flash. IMPORTANT ISSUE - the memory usage output given by the linker for program size used DOES NOT equal the actual flash space used when programming. INVESTIGATE: did I set a memory space that doesn't lie on a page boundary? or do I just need to increase the flash space allocated to the bootloader
