hi guys!!Well, I've got trouble with sending a some data to memory mapped slave. My PCIe just has one BAR. That Bar has a size of 4kbytes - 12 bits and my memory mapped slave has a 10 bits of address width and 32 data width (memory mapped slave has address are 0x0000_0000 to 0x0000_0fff). So my questions are: 1.- if I want to send data to memory slave, How should I fill BAR?:confused:....... Bar has size of 4KBytes and I dont know which bits are of datas and address. 2.- Why dooes BAR has 12 bits if my memory mapped slave has 10 bits??:confused: Well, Iill be thanking for your replys!!
