I have been using it on a Novena (which has the "predecessor" board i.MX6, a 32 bit architecture, and does feel very slow; I am assuming the new board will be much faster), and on the Overdrive, which we use as a build server. Guix as a package manager is easy, but I am not very knowledgeable on how to install the complete system. >From what I understand, they use a stock Linux 5.7.0 kernel and publish a kernel config file; we should be able to produce this for Guix with linux-libre. > CPU: NXP/Freescale i.MX8MQ with 4x ARM Cortex-A53 cores (1.5 GHz), > 1x Cortex-M4F core.

There is a project to develop an LS1028A module with two A72 cores and up to 16 GB RAM: https://nlnet.nl/project/MNT-Reform/ It is expected to be more expensive and to not be available before next year. So maybe it will be possible to upgrade, depending on how long the adventure will last - I was a bit disappointed that the Novena has been a one-shot experience. And there is the EOMA68, which has not materialised. Oh, and one big drawback: The HDMI output requires a proprietary firmware blob. Given that I am using my laptop mainly for working attached to a large screen, that is a big problem. Since you posted your message, there has been a librelounge podcast, which I have not yet listened to: https://librelounge.org/episodes/39-mnt-reform-with-lukas-hartmann.html Andreas
