Can we flash #PineCone #BL602 ... From Arm64 #Pinebook Pro? Let's find out!

https://github.com/lupyuen/lupyuen.github.io/blob/master/src/flash.md

#PineCone #BL602 responds to #Pinebook Pro at 2 Mbps ... So far so good!

Flashing #PineCone #BL602 from #Pinebook Pro ... Fails with the same error that was previously reported ... Will retry with lower baud rate

https://github.com/bouffalolab/BLOpenFlasher/issues/2

Nope lowering the buad rate to 9600 doesn't work ... Let's reverse engineer the #GoLang #BL602 Flashing Code and see what it's doing 🤔

#PineCone #BL602 can be flashed on #Pinebook Pro with the #RustLang "blflash" tool yay!

@lupyuen Heh, the last time I ever saw baud rates mentioned was like the 80's, 90's... 2400 baud modems and all that fun stuff to dial into BBSes with.

Ye gods, that was slow.

@trinsec Well with Embedded HW, going slow is usually more reliable 😉
