Hello,

I am getting different Unique Id for each FX2 controller if REVID register value is 1 but if  REVID register value is 4 than I am getting 0 as unique id for each FX2 controller, which is not unique. Why Unique ID is NOT unique for REVID:4 FX2 controller?

Hi Aniket,

The reason for same Unique ID for the REVID register value 4 can be the Revision of the chip which you are using currently. Can you please check the chip revision number of your FX2 controller?

Regards

Hello,

Thank you for your response , I totally understand my REVID register value 4 because my chip revision number of FX2 controller is 4 but why I don't get unique id when REVID value 4 . Any relation between REVID and unique id ?

Hi Aniket, 

REVID value can't be changed by the customer. Can you please let me know how are you changing it? Also, Please share the screen shot of the same unique id for REVID = 4.
