Hello,

To drive my BLDC motor i'm using the Infineon BLDC FOC sensorless SW example for TLE9879 EVAL kit. it working well
However when i use this SW with my own circuit (electronic control unit) based on TLE9877QXA40 IC i'm not able to spin the motor
To configure the SW, i have used in keil µvision configuration wizard with config.icwp file of TLE9879 EVAL, i have just modify the target (TLE9877 instead of TLE9879)
For current sensing, i have 10 mohm resistor instead of 5
I don't know what is the main difference between my own circuit and the circuit of the TLE9879 EVAL kit
What peripheral i have to modify the setting (AD2, BDRV ....etc)
what is the good values or what is the registers to modify ?
thanks in advance for your support
