I'm using p#522 here - just minor tweaks for cleaner output and a KurtE Edit that works between 506 and 507.

What Teensy is in use? Is it one that is 5V tolerant?

From 2 buttons FWD and REV ? Is the motion to stop when the button released - not return to zero?

The Bootloader responds to the button by a hardware signal on the board.

@MeBoop: Writing to the SD in faulted state is suspect? Lots of overhead and moving parts have to be working for that? As noted - some faults allow USB Serial.print() others do not - but returning...

@MeBoop - indeed - would be great to see your 'crash trace dumo' code.

Looks right for FAT32. Fat16 was big enough for MS-DOS as HDD's grew - much more so accounting for var sized clusters with compression factor of 16:1. Even Win95 with FAT32 couldn't fit FAT in...

Great! Also easy to use :: #define WIRE WIRE2

Not sure where those pin numbers came from they don't seem to match any 32 bit Teensy card. The T_3.5 and 3.6 can use ALT WIRE on pins 7&8.

The T_4.1 package is : LFBGA196 and 12 x 12 mm, 0.8 mm pitch, ball matrix

The 1170 package is : LFBGA289 and 14 mm x 14 mm, 0.8 mm pitch

There was a note IIRC the board would have to be bigger...

As noted those pins are for Wire2
So all the WIRE commands need to use WIRE2 not WIRE

That should select the right internal hardware to connect those pins.

Glad you got it - there is an #if 0 in setup that will quickly confirm Faults are trapped as configured.

Awesome. Let me know if anything changes - the git.LFSIntegrity should match? We can manage any updates but that helps formatUnused look useful and improves/updates LFSIntegrity.ino.
