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. https://youtu.be/CIpa3_70PCY?t=17135

You can do it manually, but a LA will save your time. BR, Alan On 4/18/21, Sathish Touch energy <sath...@touchenergy.in> wrote: > Hi Alan, > Thanks for your support.
