Dear support,

The example from NXP is not working. Attached is the result showing the battery voltage, which is not correct.

Please help send a new example project file for the RD33771CNTREVM EVK board.

Thank you.

Best Regard,

Wittawat

Hi, there is only one firmware on the website under this eval board. 

there is NO documentation on how to use the board or use the software. the sw is for a 100pin s32K144 device but the board has a 64 pin device.. so where can i find the sw package for this eval board set?

Hello @gzleng,

I’m experiencing a similar issue with the RD33771CNTREVM HV BMS. I’ve configured two clusters—one with 12 cells and the other with 11 cells—powered by a 23S battery pack, and adjusted the cell mask accordingly.

I am encountering a Timeout error in the BCC_IsConverting() function, specifically within BCC_ReadRegisters().

If you have found a solution or made progress, I’d appreciate any insights.
