  1. ff560000 Audio Codec PHY is the operational base address of the audio codec and the registers will be listed as an offset to that address.
  2. Hi guys, If I want to write to Address: Operational Base + offset (0x0470) ACODEC_DAC_ANA_CON12 with 55 what am I doing wrong as keeps telling me wrong address. I am root but most have the Operational base address wrong which thought that would be the codec base + 0x0479 store data there? ff560000 Audio Codec PHY fff80000 System SRAM(256K) ff800000 A35 DEBUG Tried several base addresses and just get an error as root. I thought it would be something like echo 0x60 0x40ff0168 > /sys/kernel/debug/vad/reg What I am trying to do is just see if there is register that
  3. Yeah I think they beefed up the audio port as it was a little flakey. I desoldered the broken sd connector and it will run but just mmc. Its just gathered dust since the raspberry 4 as the 4 lanes of pci-e are actually hard to populate. PS my fave Rockpi would be the RK3308 Pi-S if they actually did publish how to interface the x4(x1) VAD mics. Its an average general purpose SoC but for voice AI if there was more info it would be exceptional.
  4. Its been a while @Igor but yeah eventually with drivers I got great both way access speeds. I was messing around with drivers but there was a Realtek driver that seemed to do the trick but if there are Rockchip drivers and as above even better. I dropped the RockPi4 and somehow like a coin it landed edge up on the SD card and has since gathered dust, but also due to the Pi4 that mainly I play with now. I never got round to benching the RPi4 with those exceptionally good value 2.5Gb USB ethernet adapters, but the adapters from what I found are really good.
  5. There is what chwe said as the Armada 1500 is pretty mewh but I think it does have a zilog audio dsp and could make a good hack for a network speaker/mic image. I wonder if you could hack an image as embedded soundcards with dsp especially AEC are still far from cheap.
  6. Dunno what I was doing with the driver!!? Finally got rid of the cdc-ncd driver and used the r8152 driver [rock@rockpi4 ~]$ sudo lshw -C network [sudo] password for rock: *-network:0 description: Ethernet interface physical id: 9 logical name: eth0 serial: da:19:c8:7a:6d:f4 capacity: 1Gbit/s capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=st_gmac driverversion=Jan_2016 link=no multicast=yes port=MII *-network:1 desc
  7. I didn't get much further as my scrapyard spare x86 for some reason just dies when I try to install ubuntu. Blingdows installed ok and if I go from ubuntu server to windows client iperf both x86 then same as before.

  8.

  9. Nope I forgot to be honest its confusing and totally forgot as been trying many things and it just seems the rockchip code depending on slave or master. I will do now though as its not just this 2.5gb USB all are useless but strange thing is from memory my plugable 1gbe usb gives exactly same results, I mean exact same figures if that 300+ level is a max or same with g_ether OTG For £20 2.5gb which actually it isn't true they will run on existing as they are pretty picky with quality and length but reasonable cables rather than my usual battered spagetti 2.5 runs great. I am going to du
  10. Apols about that can not even work out on the forum how to get horizontal scrolls even though managed it with one somehow? So struggling with this, but its not the adapters as we have seen in windows they works near max both ways. Without affinity on the rockpi4 it doesn't cope with the load as well as windows but can as a client manage over 2gbs But why as a server it plummets to 400gbs with affinity I am not really sure. What I don't know is how other SBC react the same as thinking its something to do with the Rockchip code as the rk3328 has a similar performance profile and wond
  11. Here is -c connect as client same again on .5 sec
  12. Here is the cpu cores with entropy and the corresponding iperf3 run -R from the rockpi4
  13. Just an update but got the Cat6e cables was still the same. Also it dawned on me when I tried to set up OTG USB ethernet on the rockpi I got exactly the same results. That was a while back and forgot about that. Anyway rummaged through my spares and bits and built up another windows 10 machine C:\Users\Stuart\Downloads\iperf-3.1.3-win64>iperf3 -c Connecting to host, port 5201 [ 4] local port 50138 connected to port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 277 MBytes 2.32 Gbits/sec [ 4
