Hi, 

I want to establish communication ( via TPL) between S32K144 -> MC33664 -> MC33771C but i only get Status Error 3 - Communication timeout. (I checked that MC33771C is awake.)


I'm using Simulink project provided by NXP - bms_s32k_mc33772c_tpl which i have edited to get only Stack and Cell Voltages.

Has anyone come across same issue?

 

Using oscilloscope i saw that CSB_TX pin is always HIGH. Shouldn't it have been switching LOW - HIGH to send data?
