Zynq7000 030 PL MIS Issue

Dear All,

 

I have a question as below,

I used Zynq030 bank 33 and bank 34 to interface with the 4Gb DDR memory, so there are some unused pins which located on bank33.  Can these unused pins be used as GPIO?

I hope get get your guys' support and suggestion.

 

Thanks,

Felix

Hello @Felix_Xiao ,

 

I suppose that you can use the unused pin in Bank33 as the GPIO.  Please try to set your pinout to the GUI, and then validate the design.  If it has an error, you can not proceed to next step.  Attached is the UG586, p.43.

 

 

Best regards,

Hello Kshimizu,

 

it is a good idea and I have checked by vivado , the unused pins can be defined as the GPIO.

 

thanks,

Felix
