Hi. Victor....

A Linux (uClinux) Board Support Package is running fine.

If you look at the log above, boot is working fine.

Shon.

Hi Shon, 

Unfortunately, this board support package is from a third-party provider. I recommend contacting their support line, as they will be able to provide correct information.

If you would like to try our examples please download the SDK. There are several USB examples that can get you started. 

Best Regards, 

Victor

Hi SON MINKYU, 

The circuit looks fine. Are you running a Linux (uClinux) Board Support package on your board?
