FX3 enumeration with custom VID/PID

 Hi,

Using FX3 dev board I wanted to check how FX3 enumerates with custom VID/PID.

EEPROM - Atmel 24C64. Tried to follow image format from AN68914 (http://www.cypress.com/?docID=31024) and some forum post:

8-bytes:

1.: 'C'

2.: 'Y'

3.: 0xYY  (EEPROM Ctrl)

4.: 0xB2  (Boot Mode)

5.: 0xZZ   (PID LSB)

6.: 0xZZ   (PID MSB)

7.: 0xZZ   (VID LSB)

8.: 0xZZ   (VID MSB)

Created image file 8 bytes using hex editor like this:

43 59 06 B2 B4 04 F2 00

and programmed it to EEPROM using separate programmer.

I hoped that it will mean the following:

C; Y; 100kHz, 8KB, execution file; 0xB2 image type; PID (0xB404 or 0x04B4); VID (0xF200 or 0x00F2);

The result was that Windows detected (if detected at all) device with incorrect PID: USB\VID_04B4&PID_0053\0000000004BE.

What is wrong with above presented sequence of 8 bytes ?

Thanks.

You seem to have got the order wrong, Please look at page 6 of the app note there is a example you can use as reference

Tried another ordering, but the result is the same - VID_04B4 PID_0053 instead of values from EEPROM.

B2 06 59 43 04 B4 00 08

USB\VID_04B4&PID_0053\0000000004BE

 What must be the address (A2 A1 A0) of I2C EEPROM for FX3 to boot from it ? What if we will have several EEPROMs (one for boot, other for data) ? As I understand, for FX2 you have a table of I2C addresses for boot EEPROM  http://www.cypress.com/?docID=30172 page 14, table 7. Do you have similar table for FX3 ?

http://www.cypress.com/?docID=31024 has this information and explains the reason behind the addressing as well. Please have a look at it.
