I can not program S32K144 EVB

[ebookkankan]

 Dear:

       When I use the board S32K144 EVB, the reset light is always on after connecting the USB cable. The program cannot be written into the board by "S32 Design Studio".  I want to know what caused this and how can it be fixed. Please help me.Thank you very much.

Hi wang zhe,

Please download the schematic of the S32K144EVB Evaluation Board, then check the connection of J107.
You should notice the version of your own board, you can find the version at the bottom side.
Make sure the power of MCU is from P5V_SDA_PSW instead of P5V_SBC.

Best Regards,

Robin

Thank you for your answer, but the problem is still not solved.

Would you please let me know the version of your S32K144EVB?(The schematic of several version for S32K144EVB are different.)

My board info is SCH-29248 REV B1, I connect Pin2 and Pin3 of J107. I am able to debug it when plug USB cable at J7.

Please select the Emgerency Kinetis Device Recovery by Full Chip Erase.

If this doesn't work, then please try to use the P&E recovery utility mentioned in Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power. )

Best Regards,

Robin

Hi @Robin_Shen ,

I had similar issues but just D2 LED is ON in my case.

The solution didn't work for me and  do not have access to the page you shared for P&E recovery utility. Can you please help me find a solution?

[Robin_Shen]

Hi @Robin_Shen 

I tried all this solutions and none of them worked for me. 

I had got another s32k144 board but even that is in same state now. I had just connected MC33772B evaluation board to it. 

I am not sure what the issue is. Because something has gone wrong on both the boards. Is there any other way to fix this? The U11 chip on both the boards eats up when connected to power supply.

On one of the board, I am not able to powerup using 12V. Even though J107 pins 1-2 connected. 

Thanks,

Rubeena
