2017-02-23Speed up file upload enormously.Paul Selkirk
We need to start with a long serial timeout, in order to catch the reboot messages for a firmware upload (this has to be done through the bootloader). But once we start sending the file, cut the serial timeout to 1ms. (I've tested it down to 1us, but that may not work for everyone, and it doesn't improve performance in a statistically significant way.) This brings the time to upload a 4.5MB bitstream from 38:23 to 1:25.
2016-12-21Rewrite core upload loop to simplify and fix race conditions.Rob Austein
The main loop in cryptech_upload:send_file() was much more complicated than necessary, and also contained some hidden assumptions about serial I/O timing which happened to fail on the first two machines I tested. We already had a perfectly good buffered-input function, so rewrote to use that, and simplified control structure in the process. In theory, the new code should work in any environment where the old one did, but this has not yet been confirmed.

2016-07-08Add upload from firmware tarball, gussie up command parser, add dire warnings.Rob Austein
Command parser now enforces little things like mutually-exclusive required options so we warn users who attempt something silly. Preferred source for uploads is now the firmware tarball installed along with the client software; we still support uploading from an explictly-specified source file, but one must now say "-i file". Updating the bootloader is dangerous, we now say so and also require an additional option before we'll even attempt it. For the record, while testing this I did manage to brick my Alpha and had to use an ST-LINK to recover, exactly as predicted by the new dire warning.
