Another stupid flashing cable question HP-30b / HP-15C CE

Quote:As it can't get worse, I swapped the TX/RX cables and tried again. Nothing happended, MySamba reported "No connection" as expected.

Well that proves that the bootloader/MySamba uses handshaking at least. And that your cable is good. Take your "wins" where you can!

Quote:...but my only Windows alternative was XP.

That'd work but you have to load the Atmel USB-serial driver included with SAM-BA 2.16 (I've done it). Win7+ has that built-in and it is automatically installed.

Quote:It never worked as expected.

José Divasson says that he's "bricked" multiple HP-15C LE's (Atmel AT91SAM7L128 based calculators).

Since the calculator displays "Erased" I assume that it has a custom bootloader.

I have no suggestions left. However I have a theory. That could take a while to post.
