Hi there,
I bought a Rev D board back in '11, serial number 4007. Built it, run it - everything ok. I remember firwareware updates through 0.9 and looks like I managed to load up the 1.0.0 firmware too, but sadly it was put away when I emigrated in 2013.
Fastforward 6 years and two kids, and fignition is back. Plugged into a LCD screen, all is well. Until I broke it.
I was typing on the little keyboard, but my fingers were carelessly on the back of the board, and I've probably shorted out something.
Anyway, now all I get is a blank screen :(
I've checked voltages, and I'm seeing 5v on pin 1 of the ATMega, Also at top pins on the left switches, but 0.7v on the rest.
Holding down the left switch gets me a solid red LED light when I plug in.
USB to Ubuntu gives me the sad read error
usb 2-1.2: new low-speed USB device number 88 using ehci-pci
usb 2-1.2: device descriptor read/64, error -32
usb 2-1.2: device descriptor read/64, error -32
and there's nothing about USBasp for 05dc 16c0 in the lsusb command
inevitably avrdude is sad too
avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='
www.fischl.de' product='USBasp'
So this is a 1.0 release, which has the big change for audio support rewriting the firmware/bootloader. My RevD doesn't have audio input, but when I read the release PDF it didn't jog any recollection about running the Migrator hex; anyway I do remember seeing it was running 1.0.0 (or 1.0.1) when I broke it.
I'm stumped on what to check next, I don't have an oscilloscope or a ISP, but these could be sourced if necessary.
Thanks for reading this far.
Cheers
