I explained above what zram is created for. OPi3LTS should have 2G of memory, so having 1G of zram makes perfect sense here.

@fevangelou nice guide. THX! but maybe it would be best to have the instruction in an separate topic! in best case it gets also pinned. so new users can find it much easier than scrolling though 18 pages (in this thread. there is also the 4gb thread) to find it......

@Ducdanh Nguyen you should be able to see it on the board https://linux-sunxi.org/AXP_PMICs

You are completely right - at least 50MB one is there /dev/zram1 on /var/log type ext4 (rw,nosuid,nodev,noexec,relatime,discard) But big 987MB /dev/zram0 isn't at all - so it looks like it's useless and could be removed from zram config, right? Both mystic /dev/mmcblk2bootX are still in question

Hi All What is current working image for banana pi pro? Can't find any except one in archive (bookworm) which is not perfect.
