I had to put this project on hold back in December. I just fired it up a few days ago but none of the MOSFET gates are driven by the TMC262. I am reading back the internal sine wave table and I see the values changing. Both OLB and OLA flags are set indicating an open load on both phases.
I did connect a storage scope to see the gate driving voltages after power up (and initialization) but there is no activity on any of HA1, HA2, LA1, LA1 or HB1, HB2, LB1, LB2 outputs.
I made 2 more boards and all have the same problem.
Is it possible to blow all 8 outputs on all 3 prototype boards? The first board was running for a few days.
