Hi Casperites, Thank you Jack for bringing up this subject. I encountered some 10GbE issues with tutorial 2. It could be a soft/firm/hard-ware version mismatch issue and I was wondering if I could get some hints to fix it.
I did compiled and setup this version : - https://github.com/casper-astro/tutorials_devel/tree/workshop2019/roach2/tut_tge - https://github.com/casper-astro/casperfpga But I got little success with it: - Data was flowing out (gbe0_tx_cnt was rapidly increasing), which is good. - But no data was received (gbe1_rx_frame_cnt=0) - Script died on 'gbe_tx.read_txsnap()' -> AttributeError: 'str' object has no attribute 'read' I was suspicious about my DAC/AOC cables but they seem fine since I can wireshark the output stream on my server. >From what I saw, the python script doesn't seem to have any effect on the tx >interface (keeps the default values) : Ethernet II, Src: 12:34:56:78:00:00 (12:34:56:78:00:00), Dst: MS-NLB-PhysServer-02_01 (02:02:00:00:00:01) Internet Protocol Version 4, Src: 192.168.5.20, Dst: 192.168.10.13 User Datagram Protocol, Src Port: 10000, Dst Port: 60000 Any hints on that, please? I'm also wondering if the gbe?_linkup led/registers are fully functionnal since the leds are still ON when I pull the SFP cables from the cages and I got those warnings after programming the FPGA: WARNING:192.168.40.96:192.168.40.96:gbe0: odd register name gbe0_linkup under Gbe block WARNING:192.168.40.96:192.168.40.96:gbe1: odd register name gbe1_linkup under Gbe block Many thanks for your help, Cedric -- Cedric Viou <cedric.v...@obs-nancay.fr> Ingénieur de recherche Station de Radioastronomie de Nançay, Observatoire de Paris, PSL Research University, CNRS, Univ.
