Receiving error "Unable to load libusb0.dll" on S32M24xEVB-L0

[JimmyFang]

Hi NXP Techsupport,

I have been facing an issue regarding flashing the S32M Dio example to the NXP S32M244 EVB I was wondering if you can give me a bit more insight into the error.

Here is some addition information:

• After installing all related NXP packages for model-based development tool I am unable to flash the code onto the NXP evaluation board due to an error message Unable to load libusb0.dll.
• Here is the error message:

Hello,

From your description is hard to judge what is the issue.

Which exact SW packages have you installed?

For S32M Dio example you do not need any dll libraries. Just he output file (elf).

I am confused what steps you have taken.

If you can list them I can try replicating them.

Best regards,

Peter
