IOIO no longer connecting to the computer

[Kevin Chambers]

Before when I connected the IOIO to my PC it would show up as connected to COM3. I was having some problems getting helloIOIO to work and tried to update the firmware.

To get into the proper mode I:

-Disconnected IOIO

-Shorted Boot pin to GND

-Connected IOIO PC

-Removed connection from boot to GND

Then instead of the yellow light flashing 5 times it just flashed continuously.

So I tried:

-Disconnected IOIO

-Shorted boot pin to GND

-shorted pin 1 to GND

-Connected IOIO to PC

-Removed connection from boot to GND

-Removed connection from pin 1 to GND (or left in connected, tried both ways)

Now no yellow flashing light at all.

I've tried 

-Disconnected IOIO

-Shorted boot pin to GND

-shorted pin 1 to GND

-Connected IOIO to power supply

-Remove connection from boot to GND

-Removed connection from pin 1 to GND (or left in connected, tried both ways)

-Connected IOIO to PC

but it will not show up as connected to the computer so I can't flash the firmware.

Any ideas?

If you're now connecting the IOIO just to power, are you getting the LED to fast-blink?

Also, did you try connecting to a different port / different computer?

Connected just to power I cannot get the led to fast blink, I've tried:

-Connecting it to power

-connecting boot to GND, connecting IOIO to power, removing connection from boot to GND

-Connecting boot to GND, connecting pin 1 to GND, connecting IOIO to power, removing connection from boot to GND, removing connection from pin 1 to GND

I tried with connecting the IOIO to a different port and with a different computer. No luck

When you connect to power with the boot pin shorted, the LED should be on while the short is on, then blink a few times when you let go. Is this happening?

[Kevin Chambers]

When doing that, the yellow stat LED is on while I have the boot pin shorted to GND, but the second I remove the short from the boot pin to GND the yellow stat LED turns off right away. No blinking at all.

(I'm assuming this experiment has been done with no USB connection between the IOIO and the PC, i.e. a "cold" boot)

This is definitely not the behavior of a good board. Either something in the hardware or in the bootloader firmware is messed up. If you have a second IOIO or a PIC programmer you can try re-programming the bootloader on this board. Otherwise, I'd return the board to wherever you bought it from, sounds defective.

[Kevin Chambers]

That is correct.

I went out and bought another board which is working. Unfortunately I can't return this one due to soldering on connections before I realized it wasn't working. How can I reprogram it with the new IOIO?
