Always get Fault:DRV in FOC mode during startup .

]

Hello ,

  I diy a VESC6 board and double checked schematic and PCB, it looks good.

 In FOC mode ,I got Fault:DRV during startup every time, during in BLDC mode  it work fine and detect motor R,L is OK.

What's going on in FOC mode ? ....software problem ? hardware problem ?

:-(....

I do not want to modify DRV8301 chip setting ,because the default setting of DRV chip is OK, ,so in my design I remove SPI signals for DRV8301.

Is it OK ?
