The Amserve call home unfortunately no longer works; it just seems to
eventually get answered by voicemail. Shame really.

However it does do a ymodem download and it seems to accept Q;Q; format
blocks that way. Haven't quite figured out what it does with them yet
though, other than print the details to the serial console.

Anyone like to recommend some ARM decompilation tools? I've just used
objdump to disassemble the PBL, but I'm sure there must be something
that can be a bit more helpful?


Is this real - that's the first thing I think every morning.
