So I’ve just finished my Ambika build, I thought everything was well but it turns out that one of my voicecards is not working.
I’ve ran through the following troubleshooting steps and am looking for a little extra advice.
- Checked the components and orientation against a known working card (with the exception of breaking out a magnifying glass for the ceramic caps).
- Confirmed jumpers are correctly set
- Moved faulty board to another location, fault followed the board.
- Swapped ATMega chip with another.
That final step was a bad mistake. The fault followed the originally faulty chip onto another board and the working chip that went into the faulty board is now also dead.
I’ve re-programmed the faulty chips, they happily take the firmware, but are still faulty on whichever board I put them back in to.
Sometimes the data light will come on upon startup and sometimes it does not, when i assign or un-assign the card to a part the light will not change from it’s original state.
Whilst I wait for some replacement chips to be delivered, does anyone have any wise suggestions on how to further my diagnosis of my faulty card?
