I have following problem with SAM-ICE. ARM processor no my board is not detected.

When I connect USB-blaster (just for checking the JTAG) the processor is recognized,

so Jtag connection is correct.



Here is log from J-Link driver:

Can you help me with this?

Hi Alex!

Thanks for quick reply.



I'm working with custom hardware and it seems that makes problems

I've just connected SAM-ICE to Arduino Duo board and can read device ID,

so the programmer is not damaged. I've tested with second one with the same result.



I will continue to investigate the problem.

Okay,

problems solved. There was another device in JTAG chain that was incorrectly connected.

I've just removed it and now can read ID from uC. Thanks for your help.
