Hi @mariuslucianand,
I received the BMS development kits for (SPI 6-cells and TPL 14-cells) options. Meanwhile I am still waiting for the second device of TPL chain. I tried the SPI 6-cells BMS and the measure output results are working as expected. I can read "packvoltage, packcurrent, 6-cells voltage and NTC temperature.
In addition, I tested the TPL 14-cells with a single device and able to measure up to 14-cells voltage value, total Packvoltage and NTC temperature too. Apart from that, I have some issue to read the pack current (See attached - Single_TPL..., BMS_Single...., Single_MC33771TPL.slx and .pmpx). The packcurrent on freemaster always displayed at "0". I was wondering whether my 33771BTPL or 14emulator hardware failure? or my Simulink wrong settings? I checked the resistance for each of the hardware slider using a multimeter. Since, I was able to read all the 14 cells voltage except the pack current. @mariuslucianand, I hoping that on your side can try to run the device test for my Simulink R2018B file.
However, 6 cells SPI setup has no issue to read all the parameters. (See-attached: Single SPI.....)
I read the following tutorials to ensure that I can properly configured all the hardware wire connection:

and the UM1143 for the 33664 jumper wire connections.
Thanks for your helping @mariuslucianand . I look forward to hearing from your reply.
Regards,
