Hi, I have a problem. If you can help that would be of great help.
I'm an undergraduate student. I'm implementing pci protocol for my project in the uni. Aim: My pcb has to communicate with a pcb (contains Intel microcontroller + pci bridge) via pci protocol. In my pcb the microcontroller is Renesas (V850) and it doesn't have a pci controller. I did not use any standalone pci controllers in my pcb. I do not know if it's possible to implement the pci config space registers in my microcontroller. I do not have DeviceID and I suppose I can use any random number. Also, the Intel pcb is not reprogrammable. All I have to do now is to implement config space in my device and power on and check if the device is getting detected. For this the Master (Intel pcb) has to read the config space and send IDSEL signal. I'm going through the verilog code of the admin in this forum. The verilog code given in Opencores forum is very complicated and I'm not using wishbone. I want to map the device to memory space and did not understand the exact implementation of BAR. Can you please give a snippet of code for implementing the config space? Thanks & regards S Jamadhagni
