Hello, In the interest of the community, I just wanted to offer some possible insight. In my years of experiences with balbes150, he is not pretentious or arrogant. Multiple languages and translators often lack the subtleties in language that can lead to misunderstandings. English is not the first language of many here, including balbes150.
This guy has done as much or more for the Linux on ARM community than almost any I can think of. He volunteers the result of his efforts freely and commits a huge amount of his time to make all of our ARM lives easier and better.
Please understand what may seem like a critical comment, may just be a multi-language induced lack of subtle cues.
Have fun.

Totally agree to this.

I tend to believe that @CyberManifest maybe has managed something simpler than what most of us thought mandatory for external media booting of any OS we want, with just the latest khadas ubuntu flashed into the EMMC of a VIM2 ?
i can see
Manjaro-ARM-minimal-kvim1-19.07.img.xz — Yandex.Disk
i suppose this is the promised file… let the fun begin
here is my verdict on my VIM1pro which initial situation was (uboot, kernel and ubuntu):
kvim#version
U-Boot 2015.01 (Oct 30 2018 - 15:53:59)
aarch64-none-elf-gcc (crosstool-NG linaro-1.13.1-4.8-2013.11 - Linaro GCC 2013.10) 4.8.3 20131111 (prerelease)
GNU ld (crosstool-NG linaro-1.13.1-4.8-2013.11 - Linaro GCC 2013.10) 2.23.2.20130610 Linaro 2013.10-4
khadas@Khadas:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS

khadas@Khadas:~$ uname -a
Linux Khadas 4.9.40 #2 SMP PREEMPT Tue Oct 30 15:47:54 CST 2018 aarch64 aarch64 aarch64 GNU/Linux
I downloaded this file
flashed it to an usb flash drive, inserted the drive in a socket , and the rebooted the VIM1,
it DID boot and manjaro started !
but it was a manjaro 19.07 with …
[raxy@raxyManjaro ~]$ uname -a Linux raxyManjaro 4.9.40 #2 SMP PREEMPT Tue Oct 30 15:47:54 CST 2018 aarch64 GNU/Linux [raxy@raxyManjaro ~]$ lsb_release -a LSB Version: n/a Distributor ID: Manjaro-ARM Description: (none) Release: 19.06 Codename: n/a
so I consider it a fail for now,
please upload a manjaro minimal linux image for VIM1 including kernel 5.0.2
thanks
The reason is in your Ubuntu system on eMMC. It prevents you from running external Linux systems normally.
i said i was able to start manjaro successfully from my usb flash drive. the failure i mention is related to the kernel version of the manjaro distro which was supposed to be 5.0.2 and not 4.9.40
I will check this tonight and update it if it is still on 4.9 but as far as I know I used 5.0.2 with Lima support still will cross check again.
No, this is not an error of the image of Manjaro, it as the core 5.0.2. This is a bug of Ubuntu system which is recorded in your eMMC. It incorrectly formed labels and u-boot has an error that leads to this result. Read the topic about Armbian, there is evidence of this problem.
if you don’t mind, please share instructions on how to build the minimal distro from mainline 5.0.2 (or better, 5.2!)kernel source code
if my ubuntu and uboot have too many bugs, how to replace them, in the emmc, with correctly debugged versions ?
for now, all those bugs still enable manjaro to boot from usb !
This is an Ubuntu firmware error for eMMC. There is no multi-boot. Start Ubuntu in eMMC, change the root partition label from “ROOTFS” to any other. Fix the “fstab” file (change the label to mount the root partition). And you will not run anything from external media.
In fact, you start the system (kernel) with eMMC , and then the root partition is remounted to external media.
i understand my uboot started the kernel 4.9 which was on my emmc, then manjaro on the usb drive started on top of that 4.9 kernel, so whatever kernel is on th external usb (or sd drive), it is never used, am I right ?
I checked the build its 5.0.2 in all the images. Confirmed.
i am afraid at least your minimal img does not use the kernel 5 yout put in it when booted from 2015 uboot in emmc
Maybe its coz of the ubuntu on emmc.
Can you please compare the ubuntu kernel i hope you will see exact kernel which means the kernel loaded is from emmc
which kernel do yo want me to compare with which other kernel?
Ubuntu kernel with manjaro kernel.
You will find both kernel to be similar coz both are being booted from emmc kernel. This is what i understood from balbes’s explanation
