Sorry . But I formatted it to put the new image when I got the new pi working . I thought that I had some time and could do the same flash as the new card and pi and it’s crazy it worked . I did use the pi lite image this time compared to the one that was shipped with the board. Maybe that was it ?

so the problem was the image > I redid the pi3 with a fresh image also and the pins worked. but I'm running the pi 4 on my duet 3!

New pi came in today and I reloaded a fresh image and the issue is resolved ! Thank you for your help !

yeah crazy it's not working. the sd card is the one from the duet 3 box I got last week. my duet 3 is working in standalone mode for the moment. this pi had a gpio header touch screen the image before I used it as a duet pi. the question is do I wait till Tuesday with the new PI 4 and just try the sd card in it or do I flash a new complete fresh start on it?

sorry I had to snip it because it gets flagged as spam if I put it in as code. jumpers installed on 19-21 and 22-24 . pi is on my desk with nothing attached.

here is the output .

I'm going to wait till Tuesday and loaded up a fresh pi -4 and see if I still have issues. thanks, Phaedrux!

well I tried 22 to 28 ad 24 to 28 with the same output. I would post it but the form says its spam.

ok sounds good ill start the process again and display the outputs. thanks for the help!

yes sir! I started with that and did all of the testings from that post before I started this one. I can try the pin process again?

sudo cat /sys/module/spidev/parameters/bufsiz 8192

i checked and it is set to 8192

I tried making up Dupont jumpers and replaced the ribbon cable and still the same results as above. I'm thinking a duet 3 bord issue?

could I have a kernel issue on the PI?

any other thought on fixes? I ordered a pi 4 and it will be here Tuesday. Should I try stand-alone mode? thanks
