Hello,
I have just received the TLE9879 EvalKit v1.3, and I am having a problem running the BLDC_BEMF sample program. I have followed all the instruction for installing the toolchain to
develop using the Keil IDE, and I have successfully run the BLDC_Sensorless_FOC sample program. However, when I try to the run the BLDC_BEMF program, the motor tires to startup
but immediately fails. Here is a scope shot of one of the phase signals.

When I step through the debug code, I see that the program is stuck in a while loop checking on the MON_Sts() register.

Any help solving this problem would be greatly appreciated.

Hi rortiz. Did you try to push the MON button on the EvalKit board?

First like received
which motor do you use? you can reconfigure the paramater for sensorless commutation. i highly recommend you play with config wizard block commutation motor paramaters section like in the picture below. 4114.attach4114.attach
