In general, default firmware is loaded, which enumerates Cypress board with specific VID/PID. (04b4 : XXXX type)
I wish to load a short descriptor file from EEPROM, which helps bootloader to enumerate with my chosen VID/PID for loadinf firmware from host via USB. or am i forced to enumerate with Cypress VID/PID for USB boot ?
Thank you

No there is no need to boot using Cypress default VID,PID. U can configure ur own PID and VID in ur eeprom, but u should set these IDs in the inf file.

Hi,
You can refer to "I2C Boot" section of application note "EZ-USB® FX1™/FX2LP™ Boot Options" available at http://www.cypress.com/?docID=39834.
