(Since bootloader is on ROM and they >can default the JTAG to OFF). Whether the bootloader is in ROM or FLASH makes little practical difference to what it can do. If it's in ROM the only real difference is that it can't be written over. Which means it can't use that same memory area to store parameters and it can't be updated in place. That does mean it's more difficult to trash the bootloader, which is a good thing. Robert " 'Freedom' has no meaning of itself. There are always restrictions, be they legal, genetic, or physical.
