Hello Chad, Yes it is indeed frustrating... The "funny" thing is that I have another board in the same situation but I could resolve it one time and ioiodude showed application firmware version! Also, the smartphone could communicate with it in acessory mode (no external supply)! However this board sometimes works other times simply doesn't and I don't know why... but the other one just does not want to work! I totally understand your questions. This is the procedure I have done:
1. put switch in A position 2. short BOOT pin to GND pin (bootloader mode) 3. connect IOIO to PC and remove short (IOIO yellow led blinks) 4. ioiodude --port=COMx versions 5. ioiodude --port=COMx write App-IOIO0500.ioioapp 6. ioiodude --port=COMx --reset fingerprint 7. ioiodude --port=COMx versions 8. ioiodude --port=COMx --force write App-IOIO0500.ioioapp 6. ioiodude --port=COMx --reset fingerprint 7. disconnect IOIO from PC 8. short BOOT pin to GND pin (bootloader mode) 9. connect IOIO to PC and remove short (IOIO yellow led blinks) 10. ioiodude --port=COMx versions 11. disconnect IOIO from PC 12. connect IOIO to PC 13. ioiodude --port=COMx versions Domingo, 21 de Setembro de 2014 19:43:37 UTC+1, Chad Kennedy escreveu: > > > You are going to need to ignore everything past number 2 below because all > bets are off when you don't get the firmware straightened out.
