I’ve prepared a new build for Mini v2. (The improvement will apply to v1 too, but for the moment I have only built it for v2.)
Based on the prior build, there was a little improvement, but it wasn’t quite enough to solve the issues with some devices. This build has more optimized tuning on the four blue ports (all blue ports are the same in this build). The black ports are again unchanged to ensure there is a fallback in case the tunings are worse for any reason.
mkdir ~/updates
cd ~/updates
wget https://source.puri.sm/firmware/utility/-/raw/4.22.01-Purism-1-Preview-Mini-USB2/coreboot_util.sh
sudo bash coreboot_util.sh
Just as before, any feedback is greatly appreciated! If you had a problem, it’d be great to know if the improved tunings help. If you didn’t have a problem, it’s still helpful just to know that the change did not cause any problems for your devices.
And as always, you can revert to the current release firmware with use the usual instructions: firmware / utility · GitLab
