EDK 6.3 - OPB_GPIO IP Core requires a large address space

Description

General Description: 

From the XPS MHS, the following snippet errors out with the following error: 

 

BEGIN opb_gpio 

PARAMETER INSTANCE = opb_gpio_0 

PARAMETER HW_VER = 3.01.a 

PARAMETER C_BASEADDR = 0xffff0100 

PARAMETER C_HIGHADDR = 0xffff01ff 

PARAMETER C_GPIO_WIDTH = 8 

PARAMETER C_ALL_INPUTS = 0 

BUS_INTERFACE SOPB = opb_v20_0 

PORT GPIO_IO = LEDs 

END 

 

"Error message: 

Check platform address map ... 

ERROR:MDT - opb_gpio (opb_gpio_0) - C:\Data\proc_tr\BFM\bfm_test\system.mhs:27 - address space is less than min_size 511 bytes! 

c:\sdcc\bin\make.exe: *** [simulation/behavioral/system.do] Error 1" 

 

This is an 8 bit LED and should need only 255 bytes as given in the address map above. (Adjusting to 512 bytes solves the problem, but this used to work in v1.00.a.)

Solution

This problem is fixed in the latest 6.3 EDK Service Pack, available at: 

http://www.xilinx.com/ise/embedded/edk.htm.
The first service pack containing the fix is EDK 6.3 Service Pack 2.
