If I'm not mistaken, Visual Studio is a Microsoft product for MS Windows. As such, it is written for a different operating system that run on a different--and incompatible--hardware architecture.

Visual Studio Code != Visual Studio

Re: speedtest difference Windows-RPi4

Now resolved, even though one might like the raspbian repository maintainers to update apt to get a newer version of speedtest-cli.... That's not as easy as you might think. Raspbian is just debian rebuilt for armv6 (pi1 + pizero) plus additional repo provided by RPT with raspberry pi specific stuf...

Re: speedtest difference Windows-RPi4

The version of speedtest-cli provided via apt is old and has a bug with uploads.
Uninstall apt version and try installing speedtest-cli with pip3.

Re: woeful throughput on pi as raspbian router

That's not a router configuration at all.

You receive the packet on eth0, nat it and forward it on the same eth0 to your main router ... what's the point?
What exactly are you trying to achieve?

The utility contains VIA proprietary information so is closed source, but for greater portability I've updated the archive with a statically linked build.

If the EEPROM is writable and accessible it is hackable.

Re: Weston/Mesa fails on v3d/rpi4 - works on vc4/rpi3

-Dgallium-drivers="vc4,v3d" is not enough.

Code: Select all

-Dgallium-drivers="swrast,vc4,v3d,kmsro"
kmsro is needed for render-only gpus like mali, vivante, vc4, v3d etc
swrast is a fallback.
You may want to use
dtoverlay=vc4-fkms-v3d
on pi4, thats what raspbian uses.

On a side note: that ancient crap on the tools repo should be updated to match gcc/binutils version in raspbian.
