Check Firmware: Use the same firmware on FX3 DVK and check for the issue. This helps determine whether the issue is related to hardware or firmware. Check whether SuperSpeed connection is enabled in theCyFx3BootUsbConnect ( CyBool_tconnect,CyBool_tssEnable)API. Disable LPM in the firmware a...
Workaround This problem can be worked around in the FW by disabling LPM (Link Power Management) during data transfer. Fix status FW workaround is proven and reliable. 8. USB data corruption when operating on hosts with poor link quality...
