Hi Sathish, We currently do not use TPL in NuttX for our example application. But this can easily be adopted.
Bare metal example code and drivers for the BCC (MC3377xx), including SPI transfers for TPL communication can be found on the NXP website. https://www.nxp.com/design/analog-expert-software-and-tools/sdk-analog-expert-drivers/embedded-sw-battery-cell-controller-software-driver-for-mc33771b-mc33772b:EMBEDDED-SW-BCC?tab=Design_Tools_Tab You could add this to your application and together with the NuttX SPI drivers. For an example on how to do that, you could check the BMS772 example software at https://github.com/NXPHoverGames/RDDRONE-BMS772/. This example software communicates using an S32K144 to a single MC33772 BCC using SPI.

Caution: EXT Email Hi Alan, Thanks for your quick response. Yes. It requires TWO SPI WORKING at the same time. Hi Peter and Cis, Do we have TPL code in nuttx for daisy chain battery cell monitoring? or how do we proceed into the nuttx porting work from the TPL code available at https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/BMS-amp-MBDT-MC33771B-MC33772B-TPL-communication-with-S32K/ta-p/1153459<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcommunity.nxp.com%2Ft5%2FNXP-Model-Based-Design-Tools%2FBMS-amp-MBDT-MC33771B-MC33772B-TPL-communication-with-S32K%2Fta-p%2F1153459&data=04%7C01%7Ccis.van.mierlo%40nxp.com%7Cc600678a468349aabd6108d969c8e03b%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C1%7C637657133744970671%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=CIif1V4IgcbF6rPvU8DAlLkaVWjvhPJVo8vYGxbF88w%3D&reserved=0> Thanks and Regards, Sathish.

I'm CC Peter and Cis, they are the guys working on it and could give us more info.
