8.1i EDK Sp2 - The gpio_v2_00_a software driver does not correctly use Mask register to disable interrupt

Description

The software code in the gpio_v2_00_a driver includes: 

Register = XIIF_V123B_READ_IIER(InstancePtr->BaseAddress +  

XGPIO_IPIF_OFFSET); 

XIIF_V123B_WRITE_IIER(InstancePtr->BaseAddress + XGPIO_IPIF_OFFSET,  

Mask & ~Register); 

 

This should be changed to: 

~Mask & Register

Solution

This problem has been fixed in the latest EDK 8.1i Service Pack, available at: 

http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is EDK 8.1i Service Pack 2.
