ContributorGreetings tehjingy, Sorry for the delay in replying to your question. And as you asked, actually I have been battling away recently trying to get a Triple Speed Ethernet IP core to work in a MAX10 Development kit. This design uses the two mSGDMA engines that are now working, thanks for your help on that DMA area. But i am really stuck on getting a NIOSV/m processor with software to run Ethernet Frames from an ALTERA TSE.
My setup is as follows:
MAX10DevKit Design :
NIOSV/m + Tx mSGDMA -> TSE Transmit [SMALL 1G MAC configuration] <- TSE Receive <- Rx mSGDMA
RaspberryPI5 <=> Ethernet <=> MAX10 Dev Kit
I have software to initialise both the MARVELL 88E1111 PHY and the TSE in 1G Small MAC Mode
The software uses interrupts as before the Tx mSGDMA and the Rx mSGDMA and this is working because it uses the same approach as my other design which has the mSGDMA loop back working uising two mSGDMA Engines. One configured as Tx mSGDMA :: AVALON-MM -> AVALON-ST ---> AVALON-ST -> AVALON-MM -> Rx:mSGDMA
What i see is the MARVEL 88E1111 PHY doing auto negotiation with a RaspberryPI5 and saying LINK UP
But when i try to send any Ethernet frames (i am sending Frames with a IPv4 + TCP Payload), the first thing my software tries to send is a TCP 3 weay handshake, so from the MAX10 FPGA should send a IPv4 + TCP packet with SYN flag set. On the RaspberryPI 5 i use WIRESHARK to detect packets and i never see any packet being sent by the TSE.
If you could help me figure out why the TSE is not working i can send you my entire project (i am using Quartus Lite 25.1 at the moment) as a 7ZIP file to an email address perhaps ? I don;t think i can attach such a larger file to this post can i!
Best regards, Dr Barry H
Regular ContributorHi drbarryh
Since this case was created regarding the RiscFree IDE Cmakelist not appearing.
Is the initial issue resolved?
I would suggest that we continue the TSE related discussion in the other post :
ContributorHi tehjingy, no the issues are not rssolved yet because i still cannot get the ALTERA TSE to work properly in my design and to send any packets to a RaspberryPI5. I will email you my project, and i am grateful if you can try it out and suggest any bugs and fixes in the design hardware and sofwatre ?
The TSE in this proejct is now configured to use the SMALL MAC variation at 1G to try and simplify things. When i start up the Software and run it i can see it reporting that AUTO NEGOTIATION is completed between the MAX10 Dev board and the PI5. A good signa that the link is being established at the correct 1G speed.
In the software I was initially trying to do a 3 way TCP handshake between MAX10 dev board and a PI5. But in Wireshark nothing comes through on the PI5 end. There might be some sort of timing constraint problem in the FPGA but i can't seem to find it ! I have had a scope on all 8 of the DDR differential signals you can access on the RJ45 ENETA connector (you can probe them on the bottom of the MAX10 Dev baord) and i can see activity is going on all of the 8 Differential data signals, at around 800 mv.
I have also made it possinble for the MAX10 Dev board to send either UDP frames or TCP frames. The selection between TCP and UDP is done using a flag on line 436 of the C program (called msgdma_tse_app.cin the software\hal_app DIRECTORY ).
#define TCP_UDP_SELECT PROTO_UDP /* ← change to PROTO_TCP for TCP mode */
Yes I am using the MAX10 Development Kit you have pointed to in your private email. And on the other end of the Ethernet link i am using a Raspberry PI5. I have set the MAC SOURCE address to use ENETA on the MAX 10 dev kit, and to use the MAC DEST as that of my RaspverryPi5. I have set source and destination addresses and port numbers in the sofware. All of these values are set starrting on line 424 ending around line 472 for the IP addresses, port numbers etc.
Best regards, Barry
