DRV8434S: SPI Example Not Working with F280025C Launchpad

Part Number: DRV8434S

Hi!

I have been running SPI on drv8434s for a while now without issues, but with a non-TI board as the Controller.
We are now working on migrating the controller to TI, but have been unable insofar to get SPI to work as expected.
I have tried:

  • Taking a motor example (specifically 8136) + ignoring all the "motor" work + setting up the "raw" SPI as you do there. This has not worked at all.
  • Running several of the SPI samples - specifically the "best" results (no fault + coherent response) was received on the spi_ex6_eeprom sample, but I consistently receive 0x60, no matter what I send:
    • Write --> read one byte --> read one byte: 0x60, 0x60.
    • Write --> read 2 bytes at once: 0x6060
    • Read one byte --> read one byte: 0x60, 0x60.
    • Read 2 bytes at once: 0x6060

Is there some example somewhere with drv8434s over SPI?

Thanks!
Roi
