MC33771c CMU Driver

[Shivanand]

Hello Nxp community,
                                      I am using s32k358 with MC33771c and physical gateway MC33665a . I found BMS sdk for MC33772c and MC33665a . Can I use the driver by making few modifications for MC33771c as the command format and register mapping are similar.

Hello,

Yes, the MC33771C and MC33772C are part of the same family of BCCs and share many architectural similarities. Both support SPI and TPL communication modes and are compatible with the MC33665A.

Note that we provide a generic BCC software driver that supports both MC33771C and MC33772C. This driver includes register access, fault handling, diagnostics and measurement functions. It is designed to be platform independent and works with any suitable 32-bit MCU.

BRs, Tomas

Hello @TomasVaverka 
The SDK driver provided for MC33771c and MC33772c is for physical gateway MC33664a , but I need for MC33665a . If available for MC33665a , please let me know.

Hello,

As far as I know, unfortunately we do not have any drivers for your components combination. For the S32K3 MCU and MC33665 the recommended BCCs are the MC33774 and MC33775. For this combination we have plenty of ready made software as recommended by my colleague Jozef in your previous case.

BRs, Tomas
