P&E Universal Multilink connection problem with K20

Hi to all,

I'm starting to debug a new hardware with a K20 device (PK20X256VLL) but I can't get connected with target device.

Developement environment:

CodeWarrior 10.1 with all avalilable updates (1.0.1 and 1.0.2)

P&E Universal Multilink with 10pin cable

Jtag signals (CLK, TMS, TDI, TDO) and reset signal appear valid on oscilloscope during connection attempt. Power supply seems valid.

P&E Multilink seems to be recognized and blue and yellow leds lighted.

Attached snapshots of CW remote system configuration and error message.

Any suggestion? Any investigation idea?

Thanks in advance

Dear Paolo,

Sorry I didn't see any reply to your post.

Did you finally get your problem resolve?

1) Was your program working on the demo board but not your new hardware?

2) Did you try to change the USB speed? That can sometimes help.
