I tried to upgrade the firmware on the above using the copy and paste method suggested in section 8 of the manual but unfortunately the terminal program I was using would only accept one line of code at a time(didnt realise this until it was too late) and the programmer locked up. I disconnected the programmer and when I reconnected it all comms with the PC was lost. Windows no longer sees it.
Is there any way I can re-enter bootloader mode ?
If something goes wrong while you are upgrading your Pololu USB AVR Programmer’s firmware, you can always get the device back in to bootloader mode by following these steps:
- Disconnect the programmer from USB and remove any other connections that might be powering it (such as the connection to your robot).
- Using a screw driver or a small wire, short together the two little bumps of metal shown in the picture below. These bumps are called the bootloader pads. Be careful not to short anything else.
- While the bootloader pads are shorted, connect the programmer to USB.
- You should see the green light double-blinking, which means you have succeeded in getting in to bootloader mode, and you can stop shorting the bootloader pads. If you do not see the green light double-blinking, then try again.
Thank You, this sorted out the problem.
