OM13085 debug board lost firmware

[shelbyteknologi]

I have a OM13085 and after programming the example blinky it seems to have lost the firmware on the 11U35.  I've tried to jumper J4 to put it in ISP mode but it doesn't respond.  Any idea how I can recover the firmware on the debug part of the board?

Thanks

I'm trying to get the mbed firmware back so that when I plug in the board it mounts as a drive but can't find the original firmware.

Hi James,

You can download the firmware for the LPC11U35 debug probes from this link:

Firmware and drivers for LPC11U35 debug probes 

and you can use the following document as reference on how to update the firmware:

Hope it helps!
