Do any jumpers need to be changed on the RT1050-EVKB to use the 20 pin JTAG as opposed to J28 (USB)?
I did move the power to J2 and set the proper jumper.
This could be an issue... DNP everywhere that matters
And tightly between J21 and J22/J24
yes, you should remove J32 and J33 (see MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor | MCU on Eclipse). It could work without this, but I have found depending on what the OpenSDA circuit does, it is better to have it isolated.
I hope this helps,
That is a good thing to have, but did not solve it for me.
I will talk to my tools supplier to see what else I may need.
I may have to send them a board to test the probe with.
I will likely send them my RT1050-EVK, since it is not supported by the current SDK.
Erich Styger I wonder if I can use the "OpenSDA JTAG" that pin out looks better...
Nope looking at the schematic they are totally different
Now to see if my rework wizard can perform some magic and add those resistors
That "OpenSDA JTAG" is for programming/debugging the K20 (OpenSDA debug interface), not for the target processor.
Yeah I saw that.
I figured out my previous problem... the probe was in JTAG mode, not SWM
Moving forward ever so slowly... but it is FORWARD!
