Maybe try knocking the clock rate down even further? If it worked 1 time, then nothing, perhaps that is indicating it is close to working with the clock currently set to 10MHz? Oh, you can also try putting 100Ohm resistors in series with MISO and...

How should someone know this if the manual doesn't mention it (I haven't found where)? Especially if the Flexio module hasn't been enabled yet. It also works itself out after a few cycles. <EDIT> The only thing I can find in the manual related...

I've seen in many threads about Flexio being very particular when it comes to working. For example, if you set up one of their examples, it works. However, modifying things sometimes causes unexplained issues. Well in my experimenting I found...

I'm trying to put some documentation together on FlexIO and there is one niggling item: using DMA with shifters. In Flexio_t4 it is restricted to only shifters 0-3 in Flexio1, Flexio2. In rev 2 of the manual it does only say 0-3 for SHIFTSDEN...

I added a general info page and did a major revision to Interrupts.

Partially. There was a lot of work involved. Several days. It mostly helped with the low-level code as looking up all the registers and addresses from the manual is cumbersome.. I'd like the hand tweak everything further so any input is welcome.

Hi All, I started putting together some documentation on Teensy 4.1 that isn't all in one place etc. I thought it might be useful to others so I'm posting it here. It's available on GitHub. Let me know if anything is missing, needs...
