04:00 <whitequark[cis]> check this out, I'm pinging Wanda's PC while simultaneously sending 200 Mbps of UDP spam at the Glasgow NIC

04:00 <whitequark[cis]> it doesn't show how many were dropped, let me check

04:02 <Wanda[cis]> am house-cat not lab-rat

04:02 <whitequark[cis]> oh wow, if i tune one of the parameters i got it down to <3ms

04:18 <whitequark[cis]> highest i can get is about 5 Gbps

09:14 <tomkeddie[m]> Nice work, is there a schematic for the phy circuit you're using?

09:14 <tomkeddie[m]> Will be cool to build a pcap capture app - would need to implement filters to keep the USB bandwidth manageable.

09:38 <whitequark[cis]> tomkeddie: http://szfpga.com/chanpin/126.html

09:38 <whitequark[cis]> and i already have pcap capture available

10:09 <tomkeddie[m]> Thank you, this will be really useful.

10:49 <ewenmcneill[m]> For anyone else playing along at home, this seems to be the Ethernet RGMII board that Catherine is using: "Development Board 2AR Domestic GOWIN Supporting NR-9 Ethernet RTL8211F Gigabit RGMII Development Board", for which so far the only "ships outside China" source I've found is https://www.aliexpress.com/item/1005006011341346.html

10:51 <ewenmcneill[m]> (But Google Translate on the TaoBao site suggests it is about 100 Yuan in China, which makes the price on that AliExpress listing fairly expensive. The circuit board ID is SZFPGA8211FD_ETH0505 AFAICT, but that's basically impossible to search for.)

10:57 <whitequark[cis]> i just googled for "rgmii phy development board"

10:57 <K900> http://www.puzhitech.com/en/index.php?c=show&id=140 is another similar thing I've seen

10:57 <K900> It is very silly though

10:59 <ewenmcneill[m]> Your Google results are clearly very different from mine 🙂 (Unsurprising: I'm on the opposite side of the world from you.)

10:59 <whitequark[cis]> it's possible that by "googled" i meant "aliexpressed"

10:59 <whitequark[cis]> idk i just wanted an rgmii board so one materialized on my desk

11:00 <galibert[m]> Magic !

11:01 <ewenmcneill[m]> Yes, I've tried aliexpressed too 😀 It took a while to stumble on the search term that found that one. (I found a bunch of others, but few of them have the convenient 2.54mm/0.1" breakout *and* a RGMII interface PHY on them....)

11:02 <ewenmcneill[m]> FWIW I have a strong suspicion it came in some random Gowin FPGA development starter kit too. I just haven't found which one.

11:03 <whitequark[cis]> i've seen it mated with a devboard y es

13:22 <galibert[m]> Is there a point for having two bulk endpoints instead of just one?

13:22 <galibert[m]> (The T48 has two, not sure why, they're both in/out, packet size 0x200)

13:35 <whitequark[cis]> yes, it lets you have two applets right now, or also have an applet analyzer

13:35 <galibert[m]> Oh yeah, in the case of glasgow that makes it separate targets, makes sense

13:36 <galibert[m]> I guess the t48 uses ep1 for commands and ep2 for data or something like that

13:44 <whitequark[cis]> yeap

17:25 <_whitenotifier-5> [glasgow] neuschaefer opened pull request #558: swd_openocd: implement remote sleep - https://github.com/GlasgowEmbedded/glasgow/pull/558

22:58 <vincentmart[m]> Hello! I haven't received my Glasgow yet but I am really excited about this project, I am an Electronics engineer working for an IOT startup in MA. I initally thought of this board for a Profibus project that I want to create.... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/ykQPmIKNOGGCvSRYcAYhwnEs>)
