Dear Sir
I am Porting FreeRTOS MicroBlaze_Spartan-6_EthernetLite on virtex-4 Board.I am getting issue.I am compling code for Virtex-4 Board.Here is XPS Project of Virtex-4 Board the xps_timer_0 is used while in Virtex-6 they used aix_timer_0 used.please guide how i can used xps_timer_0 for virtex-4

make all

Two FreeRTOS demos are provided. The old (superseded) project for the Virtex 4 does what you want, I think, and is still available on the website and in the download. The FreeRTOS port itself is better in the new Virtex 6 project though.

If you want to know how to use the peripherals however, then you will have to look at the documentation provided by Xilinx.

Regards.
