USB3.0 FX3 how to boot from I2C or USB
Hello need some answers please,
1. the PMODE Pins can configure to boot from I2C but how?
I tried the "I2C boot" PMODE-option and the "if I2C on failure use USB boot" PMODE-option. At both options after a hard reset the FX3 reads out four bytes from device address 0xA0 at address 0x0000.
1a. How can I use this mechanism?
1b. The values in these four bytes should they have specific values for specific boot modes?
1c. Are these the VID and PID that can be used for a own driver if the device will pluged into a pc like how it is at the FX2?
2. How works booting from USB Port?
2a. Just over the VID(0x04B4) and PID(0x00F3) from Cypress?
Sorry for so much questions but at the manual, the datasheet and the header files I can not get all these informations.
I would be pleased for some answers
