Honored Contributor@FvM,
I contacted Altera support about this issue. And, here is what I got --- Quote Start --- Cypress USB device Cy7C68013A is an USB 2.0 High speed device. To enable the highest-speed PHY (Cypress) you will need to remove the suppression chip SN65220 and two 27-ohm isolation resistors between the USB connector and FTDI PHY. The MAXII needs to be re-programmed to hold the FTDI in reset and de-assert the Cypress device reset. Once the MAXII has been re-programmed the embedded blaster, power monitor, and JTAG bus switch will no longer function. Use an external blaster and re-direct JTAG between the MAXII-only and the FPGA-only through the DEV_SEL jumper. FTDI device is used by on-board USB Blaster. The customer can’t use this device. Cypress USB device Cy7C68013A is a USB interface device with an 8051 MCU in it. You can program the embedded 8051 MCU to transfer data between the Cy7C68013 and the PC. You can contact Cypress (http://www.cypress.com (http://www.cypress.com/)) if you need more information about it. There is not any reference design or example design covered th " --- Quote End --- Now the question again is, How do I communicate with Cypress from Cyclone?:confused:
