<![CDATA[Debug CoreS3]]>Is there a way of getting a debugger attached to CoreS3? From schematics it appears the GPIO19/20 for JTag is exposed on an internal J6 plug which I cannot find (HDR4 2MM). Is this this the correct way? looking at the plug it seems to be 1.25mm pitch 4pin which I think is a molex Picoblade. Can anyone confirm this?

Thanks

M5CoreS3

I've made up a USB cable attached to the DP/DN connector but still cannot get it to debug.
