Features and Overview

The SDK implements FPGA Board specific functions in the firmware and allows to access them using the host software API. These functions are:

• Firmware upload directly to the EZ-USB FX2 and FX3 Microcontrollers
• Access to SPI-Flash
• FX2: Access to EEPROM
• Firmware upload to EEPROM (FX2) and Flash (FX3)
• FX2: Access to microSD/*SD/MMC Flash cards in SPI mode
• FX3S: Access to SD card (SDIO and other functions usable with the Cypress SDK)
• Bitstream upload directly to the FPGA
• Bitstream upload to Flash memory
• Automatic Bitstream loading from Flash during start-up
• MAC-EEPROM support, used to store configuration data

A more detailed feature description can be found on the ZTEX Homepage.
