Hi Sho,

Thanks for your response.

In the platform design the base address from 0x00100000 to 0x0013ffff for the 16bit address on the avalon bus.

This time the abnormal is different. When I use the IOWR_32DIREC function, the read pulse is appear. It is very strange.

However, I try to change the address bus width to 12 bit, the base address 0x00058000 to 0x0005bfff. The signal capture from signal tap analyzer become normal.

Best Regards,

Paul
