Problem into debugging with CMSIS-DAP on IMXRT1050-EVKB board

[GottiLuca]

I've just received a new IMXRT1050-EVKB board, but i cannot debug by CMSIS-DAP interface in MCUExpresso V10.2.1 .

I copied & pasted the consolle message :

"

Any hints to solve this problems ?

Thanks,

Hello Luca,

   It seems that you connected wrong connector.

  if you are using OpenSDA on board(DAP LINK), J28 should be connected to your PC usb port via usb otg cable.

Before debugging it, suggest you'd better read and understand schematic of i.MXRT1050 EVK,  which can help you do well in future design.

Check it, please!

Have a nice day!

Best Regards,

Dear Mr. Sun,

I have connected on J28 connector with the USB cable supplied with the board.

I've done the same on another new EVK ordered which I can debug without problem.

But the first pcb has the problem that i've illustrated ; for which reason do you think that the pcb was connected trought something different  ...?
