I finally managed to kill my beloved Panda! I had a wire to one of the digital pins and I dropped the wire and it touched something else, I don’t know what it was, but the only thing I heard was the sound of a disconnecting USB device on my PC. I reconected the Panda, the light goes on very dim, but no sound on my PC that a device gets connected and nothing in TerraTerm or MFDeploy or whatsoever.
I considered my Panda USBBizi Chip lost somehow and ordered a new NXP chip, so not from GHI. Without thinking that a NXP chip would be empty!! So now I have a Panda with a new Empty chip from NXP and I want to get it to life somehow, I have tried to get the open source firmware on it, but the Panda still isn’t being recognized as a USB device, what else could cause the Panda to not be recognized? I changed the LDO already and the transistor! What else can be damaged the diodes?
