Last month I’ve tried to install NixOS again on my Librem 5. Unfortunately I cannot get any kernel from Librem5 / linux · GitLab to boot. Just a green led and black screen.
The kernel version in Can someone with serial console access try NixOS kernel on Librem 5? - #20 by ookhoi that did work for me is not available anymore.
It is quite frustrating that both uboot and the kernel still have no upstream support for Librem 5. I’ve given up for now. But NixOS itself is a great fit for the Librem 5 as it has much more software than PureOS and is more robust due to rollback support.
