Hello,
In our project, we are using TLE9877 integrated to our ECU (Electronic Control Unit) to spin BLDC motor. For SW we are using infineon BLDC sensorless FOC exemple (based on TLE9879 evaluation kit).
To flash our ECU, we are using Jlink probe (SWD mode) from segger.
We have created a new keil project for TLE9877, configuration of peripherals is done using Config wizard.
Below the description of the issue:
When we flash the ECU and the JLINK probe is still connect, the motor spin normaly
When we disconnect the JLINK probe or when we switch off the power supply and switch on agan the motor don't spin.
The motor also spin without any issue when we use the TLE9879 eval kit
Could you please help us to identify the problem
TLE9877/ Program executed only when d debugger is connected to ECU

You could check first of all if you have supply voltage on the Vs pin of the IC.
If there is at least 5.5V then please check if you have voltage at VDDC and VDDP.
If you see respectively 1.5V and 5V it means the device is powered up correctly.
If you arrived to this point, then there might be something wrong with how your program executes.

hey @User19528 ,
Copy the TLE9879 startup file from the TLE9879QXAx folder to TLE9877QXAx folder then it will work.
Best Regards,
Rohit
