MIMXRT1024-EVK JTAG not working

I have yet to be able to get JTAG to work when trying to program and debug the eval board.

I am using MCUXpresso IDE and a PE Multilink JTAG. I can program and debug through the USB, but not JTAG. When I try, I get the following:

I have SWD checked, and even tried it without with the same results.

Here is the Debugger settings:

The PE Multilink works fine when I use it with KDS IDE and a K66 micro.

What am I missing that I cant use it with the IMXRT1024?

I recommend reviewing the information on the page for the first use. Maybe need the external DC, it does not have an external DC please modify the power selection jumper or the boot source switch is wrong. The next link show, which is the JTAG for debugging.

First Steps with the NXP i.MX RT1020 EVK Board | MCU on Eclipse

Best regards,

Thanks, removing jumpers J47 - J50 worked, at least for SWD mode through the PE Micro. That's good enough I guess. Still don't know why regular JTAG doesn't.

It would be nice if the User Guide would mention that though.
