Hello,

Please let me know more details of the application/ firmware that you are using for receiving data on FX3 through parallel port (GPIF). Are you using SlaveFIFO  interface as per this application note https://www.cypress.com/documentation/application-notes/an65974-designing-ez-usb-fx3-slave-fifo-inte...

the driver lib returns the  "RES_TRANS_ERR".

>> Please let me know which host application is used and does FX3 binds to Cypress Driver (cyusb3)
