ive got the same issues as you, with the same box too!

im not that savvay enough to do what youve done, ill have to wait for a update/fix. thank you for your time and effort in finding the issue!

i was using the s82 builds, should i be using the m8 build??

you should definitely use the M8 builds. the box isn't compatible with other variants in terms of peripherals.
I'm using the build from here LibreELEC-S802.M8.arm-8.0.RC4: LibreELEC-S802.M8.arm-8.0.RC4.img.gz | by Demetris. for MXQ TV Box

what's the behaviour you have from your box? maybe I could assist with a step-by-step.

managed to run Lakka.tv easily with this:
setenv condev "console=ttyS0,115200n8 console=tty0 no_console_suspend consoleblank=0"
setenv bootargs "${condev} bootfromsd"
mmcinfo
fatload mmc 0 ${loadaddr} kernel
bootm

however, only the Lakka-S802.M8.arm variant would boot, the S82 variant doesn't boot.
maybe this will help point you in the right direction.
thanks!

managed to run your build for LibreELEC-S802.M8.arm-8.0.RC4
it seems I was missing the right uboot vars

I started it with:
setenv condev "console=ttyS0,115200n8 console=tty0 no_console_suspend consoleblank=0"
setenv bootargs "${condev} bootfromsd"
mmcinfo
fatload mmc 0 ${loadaddr} kernel
bootm

it expanded the 2nd partition, rebooted and it is now running fine.
thanks and keep up the good work!

might be that the crash is due to missing 'logo' kernel cmdline param.
when I use:
setenv fb_addr 0x15100000
setenv outputmode 1080p
setenv condev "console=ttyS0,115200n8 console=tty0 no_console_suspend consoleblank=0"
setenv bootargs "boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 ${condev} logo=osd1,loaded,${fb_addr},${outputmode},full"

I end up only with:
Starting kernel ...

and the same "Error in mount_flash: mount_common: Could not mount /dev/system" on TV

I will investigate thanks for the report

Sent from the Island of Venus

thanks very much for looking into this.
it would help to know which uboot variables I should set and what kernel cmdline to use so it boots from SD instead of looking for the system partition on flash.
as I said, the EMMC flash is broken.

thanks again

it seems actually that I get a kernel crash

Demetris, guys,
I have a Minix X8 with a broken EMMC. as I've read, this happens a lot to those.
now, my only chance is to be able to run From the SD Card.
I have access to UART console and while trying LibreELEC-S802.S82.arm builds the kernel gets stuck after the last message:
[ 3.761576@2] amlogic-thermal aml_thermal: amlogic thermal probe done
[ 3.768109@2] ALSA device list:
[ 3.771258@2] #0: AML-M8AUDIO
[ 3.774519@2] Freeing unused kernel memory: 184K (c0909000 - c0937000)

on TV is shows: Error in mount_flash: mount_common: Could not mount /dev/system

the board's spec is:
Brand MINIX
Model NEO X8-H
CPU Brands Amlogic
CPU Model Amlogic S802-H Cortex A9r4 Processor
CPU Cores Quad Core
GPU Octo Core Mali-450
Memory 2GB DDR3
Internal Storage 16GB eMMC
Wifi Connectivity 802.11n Dual Band Wi-Fi (2.4GHz/5.8GHz), Bluetooth 4.0
Bluetooth Bluetooth 4.0

I'm sure it is similar to many other board out there but so far I wasn't able to boot any LibreELEC.
I'd be glad to help test if there's a build that could work.
I've managed to run Armbian on it, with desktop (no luck running kodi however) but there the build is different as I have the right u-boot env variables and kernel, ramdisk and dtb images.
any help is much appreciated.

thanks in advance!
