Flashing fails with handshake failed #53

Closed FlareFlo closed 1 year ago

FlareFlo commented 1 year ago

Flashing using the command blisp write -c bl70x --reset Pinecilv2_EN.bin fails.

I ensured my device was authentic and validated its ID before attempting to update. ChipID redacted in output, but matches what debug display shows. output:

Handshake successful!

Try another PC / cable / try Linux. It's known that Windows have problems sometimes.

I forgot to mention, i tried that on 6.5.6-arch2-1, using both front-panel and motherboard USB-C ports, with two different cables :/

I tried with a USB-A to USB-C cable and it worked perfectly. Seems my otherwise working ports/cables are behaving weirdly.

Yay! Thanks for letting me know!
