I cannot debug with P&E multilink Universal FX into the iMXRT1020-EVK

I can debug with the openSDA implemented into the board but when I want to debug with the Multilink FX the message that I obtain is the following:

P&E GDB Server for Arm(R) devices, Version 7.14.00.00

I review all post and I try all things into the post and I cannot make it work. 

I open the jumper J27 and J28 to disconnect the openSDA. 

I don't know what else to do. 

I did a custom board and I have the same problem.

Hello Gustavo,

I made some tests on my side and I was able to debug using a Multilink Universal FX Rev. B debugger. I used the newest version of MCUXpresso IDE and an SDK example. I had to remove J27 and J28 from the RT1020-EVK to debug correctly, see image below.

What IDE are you using? Are you using an example from the SDK or your own project?

Have a great day,
TIC

Hi Victor 

Thanks for your feedback but it is not work for me. 

Yes I use one example from the SKD the iled_blinky project and I can debug with the open SDA and with external JTAG I cannot debug, I open J27 and J28 and I try with 3 different probes P&E Multilink, P&E Multilink FX, Segger J-Link and no work any of the probe. the question is with other configuration I need to change to make it work?

Hi Gustavo,

Are you connecting the debugger to J16 connector? Are you using MCUXpresso IDE? If so, when you debug with the OpenSDA and then you want to debug with another debug probe, you need to delete the debug configuration. To do this please follow the next steps:

1. Select the debug configuration file.
2. Right click on it.
3. Delete.

Best regards,

Victor
