S32K1

[Abdel]

Hello, i have S32K144 development Kit for bldc motor control.At the beginning the board functioned without any problems, I could manually control the motor (With buttons sw1 accelerate, sw2 decelerate). I wanted to test the board with "Hello Code" and then came the error message "no board detected on any of speciefied UART Communication" in Freemaster. Can you please help me to reset the board or to return to the start, so I could manually control the board again. Thank you very much

Hi Abdel,

Seems that you are test the MCSPTE1AK144_BLDC_6Step demo.(C:\NXP\MC_DevKits\MCSPTE1AK144\sw\MCSPTE1AK144_BLDC_6Step)
If you have download the MCSPTE1AK144 APPLICATION SW on "Get Started with the MCSPTE1AK144". Then please try to flash MCSPTE1AK144_BLDC_6Step demo in S32 Design Studio (S32DS) for ARM 2.2 again.

Best Regards,
Robin

Hi Robin,

many thanks for your response.

I performed the flash but unfortunately the LED on the board is still red and the LED in front of the Hall Encoder Interface flashes constantly. Can you help me please? Thank you in advance

"If the LED on the board is still red". Do you mean the D1 on S32K144EVB?
If so, the reset signal of MCU may be low(You can measure it by using oscilloscope). Which mean the project may not run at all.

After flash MCSPTE1AK144_BLDC_6Step demo to S32K144EVB, the D1 LED does not light.
Step 2 Program Base Board

And I am able to connect it in FreeMaster.
I don't have DEVKIT MOTORGD board, so just power S32K144EVB by OpenSDA J7.

Due to the definition of J107 is different, please check the SCH version of S32K144EVB. So that you can "make sure base board is configured to be powered externally".

Hi Robin,

Thank you for your answer. Can you tell me please, if i need an externel debug adapter for my board. I understood, that this board S32k144EVB has an integrated debug Adpater. If yes, which one do you recommend. 

Best regards

Abdel

[Robin_Shen]

You don't need external debugger.
If you are following the "Get Started with the MCSPTE1AK144", the step "3.6 Connect the USB Cable" and "4.2 Debug and Load" shows it will use on board PEMicro OpenSDA debugging.

Would you please let me know which project did you load at the beginning? (board functioned without any problems)
The "4.1 Select Application and MCU Programing" of "Get Started with the MCSPTE1AK144" load MCSPTE1AK144_PMSM_FOC_2Sh. In order to achieve the previous function, you may load this project again. (C:\NXP\MC_DevKits\MCSPTE1AK144\sw\MCSPTE1AK144_PMSM_FOC_2Sh)

[Abdel]

Hi, thank you for your answer. I loaded this "MCSPTE1AK144_BLDC_6Step" then this "MCSPTE1AK144_PMSM_FOC_2Sh". But it didn t work. I I have now another problem. when I connect the motor board, the light on the power supply unit is blinking.

ist it defect now? Thank you in advance.

[Robin_Shen]

Please download the documents of DEVKIT-MOTORGD.
Do you mean the LED_OK D2 blink?

Please check the voltage of below point:

[Abdel]

Hi Robin,

i mean D2 LED. I think the mosfet (Q2) is defect, because it doesnt conduct. Which one do i need? Thank you in advance.

Best regards
