For my standalone Forth, I need to be able to burn an image to the LPC2103 that leaves erased sections erased. Neither the Coridium load21xx nor lpc21isp do that, they both overwrite the rest of the sector with garbage from RAM. Though imperfect, I'm pretty pleased with the results from burn.py, which also contains an improved version of dump.py I uploaded a few days ago. It's an almost-complete implementation of the LPC21xx ISP (In-System Programming) interface.
