Grrrr. I had neglected to test before uploading, and I had forgotten to include code to replace the number at 0x1f with the vector checksum. I've now done that, and verified that I'm calculating the same checksum as lpc21isp, but when I upload with burn.py I don't have a working program; and when uploading with lpc21isp, I do.
