Issue in running motor using custom board STSPIN32F0

[x4ce]

Dear,

 

I have custom board based on this https://github.com/issus/BLDC-Drive which uses STSPIN32F0 as motor driver. I have that got that PCB manufactured & assembled but stumbled on an issue (which I assume is an issue) that it does not have feedback resistors on current sensing op-amp circuits. I have added those manually on the PCB. I am able to program and connect to the board using MCSDK 5.4.8 monitor but whenever I press start motor start-up failure occurs.

 

I can share all the files need if required but I want to know the procedure to diagnose this startup issue. I have a 2-channel oscilloscope with me and I can probe those inverting signals as well.

 

MCSDK 5.4.8 & schematic are attached for your quick reference.

 

I will be grateful of your help in this matter.

 

Regards

Shahid
