OrangeCrab r0.2.1 no longer enumerating through dfu-util #31

Closed biosbob closed 1 year ago

biosbob commented 1 year ago

i have a newly-purchased orangecrab board that is no longer enumerating through dfu-util --list.... worse, the green power led no longer illuminates when i power the board through usb; and the continually changing rgb led is basically frozen....

wanting to program the board through jtag, i connected an adafruit ft232h board to the orange crab as follows:

i also chose to power the orange crab using 5V taken from the adafruit board....

when i would run ecpprog -t, however, all of the ID bytes were 0x0; further attempts to read flash also returned 0x0....

assuming i haven't fried my orangecrab, is there any path to return the board to its original (working) state????

Hi @biosbob. The LEDs sound like it's a hw fault. If the issue cropped up with general use, you can try contacting groupgets or the distributor where you bought it for an RMA. Alternatively I've got some repaired/tested boards here that I can replace it with too, contact me via email.
