managed to handle usb disconnections!

i yanked the usb cable in the middle of the ESIDE being erased. flashhack realized that the cable was toast, and threw an error, informed the user to try to write again.

plugged it back in and hit write.

it realized that the tside has already been written, and that the kernel was already loaded, and verified the written data.

it resumed the eside like nothing happened. this all happened at an insanely fast speed because all the executable code was already in ram and was just run again.

Corvette compatibility is completely broken again. Won't talk to either car. Sometimes it won't seem to do anything, other times it'll make the digital dash freak out and display "SYS" and flash the SECURITY light but nothing else. Log of attempting to talk to my '95 is attached.

Haven't tried swapping PCMs to test the checksum thing with 0.4.3, will do that tomorrow if the weather isn't terrible. It rained today so I didn't want to go yanking the PCM out of the car in the driveway.

i haven't really changed anything between the last version and this one that should affect how things connect. please do experiment with the timing settings to see if any adjustments help.

Not sure what to tell you. No matter how many times I hit Read Calibration on either car, the same thing happens--it'll either time out nearly instantly and fail, or it'll send those burst messages like in the log and then complain about failing to become the bus master and fail.

I then switched back to 0.4.3 and it read without any issue on my '95 again. Then as soon as the PCM rebooted I swapped back to 0.5.0 and tried to read and it failed. So something changed between the two that the Corvettes don't like.
