Re: F-Tile PCIe Root Port 1x Gen3x4 - Configuration Read Type 0 receives no answer
Hello Rong, You are welcome. No I cannot read the EP_VID and EP_DID. When I am doing a read on this register I did not get an answer. Do you have a Pcie Protocole Analyzer ti check what is produce by tve F_Tile ? Thanks. SergeRe: F-Tile PCIe Root Port 1x Gen3x4 - Configuration Read Type 0 receives no answer
Thank you Rong. Do you need my project ? I can encrypted it and send it to you if you want ? The sequence I am doing is the following : Using the configuration Bus : Read @82h to get Link Rate and Link width Write 00h at @18h Read @18h to check previous Write Write 01h at @19h Read @19h to check previous Write Write 01h at @1Ah Read @1Ah to check previous Write Write 00h at @1Bh Read @1Bh to check previous Write Write 06h at @04h Read @04h to check previous Write Read @78h to get RP Dev CTRL register Read @79h to get RP Dev CTRL register Read @7Ah to get RP Dev CTRL register Read @7Bh to get RP Dev CTRL register Read @74h to get RP CAP Payload Max Using the Avalon Stream Bus Configuration Write type 0 End Point BAR0 with FFFFFFFFh @10h Wait for completion (Completion received) Configuration Read ype 0 End Point BAR0 @10h Wait for completion (Completion NEVER received. Please let me know if you need any other information. Thanks for help. SergeRe: F-Tile PCIe Root Port 1x Gen3x4 - Configuration Read Type 0 receives no answer
Hello Rong, When using a Configuration Write or Read Request the address is compose of : Bus Number(7:) & Device Nb(7:0) & Ext_Reg(7:0) & reg Nb(7:0). So what you see is the Bus Number=01h and Reg Nb=10h. By the way, I have the same behaviour with the address=00h (Device ID & Vendor ID) in the Configuration Space. Thanks for help.

Hello Rong, Nice to see you again. BAR0 in address 10h, is in the Configuration Space not in the Memory Space, so you have to use a Configuration Access. I am using the same access with my Agilex7i-R-Tile board and it is working. So this is very strange it is not working on the Agilex-7F board. Thanks for help. SergeF-Tile PCIe Root Port 1x Gen3x4 - Configuration Read Type 0 receives no answer
Hello Support, I am using the Agilex 7F Dev Kit with F-Tile configured in Root Port Gen3x4. When I am doing a Configuration Write Type 0 to write the End Point BAR0 with FFFF_FFFFh, the end point send an answer , when I follow this write with a Configuration Read type 0 to read the BAR 0 of the End point I do not receive any answer. Is there any configuration which avoid the read data to go through the F-Tile ? Is there any problem with my Configuration Read type 0 command I have attached the STP file as well. Thank you for help. Serge
