Hi all,
I have a custom MC33771C PCB that is 14S but I have it setup to read 11S througb the connector by connecting cell 4 to 5, 6 and 7 as well. I have use a few different custom MC33771C's previously and not had any issues. However, this board is acting very weird. Whenever I try and load MBDT code onto it the device switched off straight away (Shown by VCOM light) and reports a Status of "3" from BCC_INIT. I am trying to use a single CMU with TPL.
What is weird is that the MC33771C GUI when connected to the S32K144EVB through the MC33664 breakout board to my custom MC33771C works absolutely fine. I am just confused about what could be causing the MBDT examples from not working compared to the GUI?
The only other this I noticed was that the voltage values seem to take a second or so to get up to the correct voltage measurement values(Video attached), is this normal?
Thanks in advance!
