Hello everyone. This is my first post. I'm posotng because I am frustrated. My ICE does not recognise my SAMD21 chip. I get error 4109. I have checked my connections a hundred thousand times and its not that.It reads target voltage okay. But does not recognise a chip present.
However if I plug and unplug the ice from the usb port I get a new error " 'ArmDev_23' is not a device context".

I have tried everything. Changing the wires, decoupling caps and vdd core output is good. I have lost all hope. Anyone know what is causing this error? Thanks

Have a look at this post, it may help.  Also, posting a schematic and pics of how your connecting it may help.

The ribbon cable that is used to connect the ICE can be a bit fragile,  Atmel sells replacements for a ridiculous price, but you can buy the cable and connectors for about $10.  If all else fails it may be worth trying to swap it out.

Here you can order up to 5 free samples of the cable ;-)
