RE: [EXT] Re: SPI driver is not working in S32K144 EVB
Hi Sathish,
Colleagues of mine, have worked on the BMS-772 (S32K144 + MC33772B) which also runs NuttX.
To get the BCC working we've applied some patches that yet have to upstreamed to NuttX.
But you can check out the source code here https://github.com/NXPHoverGames/RDDRONE-BMS772
Furthermore they gave a nice introduction to our BMS-772 in combination with NuttX during the NuttX online workshop.

Hi Sathish,
Are you using a battery solution similar to this board:

I suggest you to used an logic analyzer to verify if the signals are correct.
You can do it manually, but a LA will save your time.
