There is one “tiny” problem with slimboxtv: slimboxtv bootloader does not allow to boot from microSD card anymore! Thus, slimboxtv is NOT compatible with CoreElec (assuming that CoreElec is booting/running from microSD)…
I noticed that recent cheap chinese android TV boxes (based on S905W2, S905Y4, etc.) require faster and faster microSD cards.
I have 3+ years old TV-box based on S912 (the last CoreElec version which supports it is 9.2.8) is running from Samsung EVO 64GB card. Never had a problem with freezing, crashes, backing up or restoring libraries.
when I try to use similar card on one of new boxes (I tried M98 Max and H96 Max, they use S905Y4 and S905w2, respectively). I can boot and do initial config of CoreElec. But when I try to copy my kodi library backup (it’s a huge 7GB archive) on this SD card, TV-box spontaneously reboots. I was never been able to copy this 7GB file to mounted SD-card (neither via ethernet, or from mounted USB flash drive).
And then I pin-pointed this to the speed of SD card. When I use brand new PNY Elite-X 64GB (this is 2023 version, available at about $5 from Amazon), I can finally boot normally, and copy/import my libraries on a new installation. The fact that PNY Elite-X is about twice faster SD-card than Samsung EVO (PNY shows 95MB/s read and 50MB/s write speeds, measured with Crystal DiskMark) probably shows that device tree inside CoreElec is not properly tuned for “relatively slow” SD-cards.
Looks like new kernel trees (CoreElec 20.2 and above) don’t know that slow SD-cards do exist. Kernel crashes when it has a lot of SD-card transactions, especially writes (when copying big file to SD-card).
In contrast, when you boot to built-in Android firmware, then mount the same Samsung EVO card, you can copy that 7GB file to SD-card without problem. Which means, built in Android does know how to handle “slow” SD-cards.
Error you are reporting may (or may not) be related to my observations.
Unfortunately, I don’t know how to tune cpu tree-image to allow “slow writes” to SD-card.
PS: CoreElec 9.2.8 on my old box does have hardware settings (some not very obvious line in the menu) which allows to switch between two speed ratings for SD-cards. I did not see similar settings in CoreElec 20.2
CoreELEC New Era is working on my H96 Max W2 (4/64 GB) with slimBOXtv in the internal memory. Internal WiFi isn’t working and New Order doesn’t work either.
