Even more flasher improvements #33

Closed edjubuh closed 7 years ago

edjubuh commented 7 years ago

After analysis of James's flasher and USB dump of official default code downoad utility, following changes have been made:

Remove all parity switches
Better retrying for write packet failures
7f bootloader initialization handoff works better (with retries)
Proper "GO" commanding

Tested on my laptop, Benjamin's older MacBook Pro, and Jonathan's laptop. Need to test on more

This worked on my Mid-2012 Retina running 10.12.3, on full wire, VEXnet 1.0, and VEXnet 2.0.

Works on Windows 10 over direct A-to-A USB, VEXnet 2.0, VEXnet 1.0

Over direct VEXnet 1.0, and sometimes over direct USB, the bootloader sometimes fails to ACK in response to the GO command. This should be fixed by power-cycling the cortex.
