Hi all,

How can I check the transfer error status in BULK transfer?

Is there any error status register?

and, if 3 times retry fails, What happens?

also Can the firmware know this situation?

Regards,

HC

Hi sai krishna,

During massive bulk transfer of image data, BeginDataXfer, WaitForXfer, FinishDataXfer functions return error and

this error does not recorvered.

cable and USB card change alter this situation, especially bad cable makes much error.

so I think communication error occurs, I would like to check error exists or not.

Regards,

HC
