MISO line always low

[CRen.1]

I have tested AutoDirver board(L6470) with Arduino and everything worked.

When I use Toradex Colibri EVA board (Imx 7) to control the AutoDirver board(L6470), I cannot get any response from L6470. The MISO line always low.

Can you give me clue on how to solve this issue?

Thank you

Recheck your wiring, reread the docs and recheck again. Test other boards. Check if logic level fit.Ither the part is broken or the error is on your side.

Thank you for the reply, I tested with different Colibri EVA board and L6470 board, I am sure the wiring is OK, but no luck. I will reread the docs and double check my code.
