Thanks for the reply. I looked at the schematics pdf that you referred to and understood that r93 and r68 have to do with the boot-order, and that setting r68 low (as is actually done by pressing the uSD boot button) would make the bootorder different.
Is that possible in software, or do I have to do that by settting up some kind of wiring? On Tuesday, November 26, 2019 at 6:38:32 AM UTC+1, Jim F wrote: > > Should be easy to do.
