UART communication between ST MotorPilot and STEVAL-SPIN3202

[EShaw.1]

Hi ST,

I am unable to establish UART communication between ST MotorPilot and STEVAL-SPIN3202.

I am uploading one of the two STEVAL-SPIN3202 examples.

Setting up 9600 baud rate (same as in Cube MX settings). Using correct COM port.

Hardware setup:

Power 24VDC connected.

USB connected.

J9: OPEN (BOOT0). (closing does not do any change)

J7: OPEN.

If I debug it:

and resume,I observe green/red USB LEDs blinking.

I am trying to connect with ST MotorPilot - result:

 

If I run it:

it does not blink red/green USB LEDS and result is the same, no matter whether If close J9 or not and reset the MCU.

Result is the same, :

 

What am I doing wrong?

Should I Run or Debug?

Regards,

Edward.

Hello,

May I ask a question, did you check on workbench interface if UART IP is available (digital i/o box)?

In the example below, it is not available...

If it is the case, I assume that you are using a WB5.Y. if yes, could you try with WB5.4.8 please?

Best regards

Hi GMA,

Thank you for the answer.

I ran WB4.5.8

Now UART is active.

I am not sure where I can find  UART IP  (digital i/o box) on Workbench interface.

In MX, Hardware control is disable by default.

 

After attempt to copmpile and run:

 

It does not fit to RAM by 24 bytes.

How can I fix this?

Regards,

Edward.

Could you try using "LL - Low Level" for "Drive Type" on Project generation option?

Hi GMA,

Thank you very much!

I changed the Drive Type as you suggested.

Now UART communication with Monitor works.

Had this same problem today. To recap for others when using STEVAL-SPIN3202:

• MCSDK-Y's Motor Pilot does not work with the SPIN3202 even though is shown as an option. You need to use MCSDK 5.4.8 and its Motor Monitor utility.
• Drive type needs to be "Low Level" when generating/updating in MC WB. HAL is too large even when using code optimization.
