PS: plz clean old image or just clean/format dump partition
mainline uboot can get some problem with usb SSD

Yes I trust you that it works fine, but it doesn’t on my device where the emmc is erased completely so there is nothing inside.
I can try the latest krescue image and see if that helps.
Thanks for testing things for me.
Where is the updated krescue image for sd card? There is no update on dl.khadas.com
Thanks for the update.
I will try this now.
Hi @hyphop
Vim1 can boot from sdcard with mainline uboot without the need of TST mode but VIm2 needs TST mode for every boot, Is there any ways to make it boot directly with need of TST mode ?
Any plan to getting to to boot without clean emmc ?
I will be releasing Vim images for our 20.08 images mostly for VIm1, vim2 and vim3, If you can take it and make it into kresq image but only if you do it separate image for each device as we manage separate packages for for each device.
Thanks.
i still don’t understand your problem
and try to clarify again 
- normal boot sequence for all amlogic devices VIM1 VIM2 VIM3 VIM3L is emmc → sd ( spi fplash excluded ), emmc always is first and only if cant boot from emmc device trying bootup from sd
- if we are using mainline uboot on emmc / sd - we have next boot sequence spi → usb → sd → emmc - for bootup linux
- sure if we have another uboot on emmc - boot sequence not same
- sure sd uboot will be ignore if system was booted from emmc uboot
- maskrom mode (TST) work fine only for VIM1 VIM2 EDGE
Any plan to getting to to boot without clean emmc ?

BTW: i can write some scripts for easy generation krescue images

Can i boot a coreelec sdcard using mainline uboot ?
- u can try
- i think yes - but need some modification
I ask because Corelec Documentation states that stock android uboot must be in emmc to boot the coreelec SD/U-Disk.
I tried to boot Coreelec U-Disk using 3-press function key on mainline uboot but it didnt boot into it. Then i converted the U-Disk to fenix Ubuntu mainline and it booted successfully.
Currently I have a running Manjaro on EMMC and dont want to destroy EMMC and only use corelec through U-disk or SD. If you have some free time, please have a look if mainline uboot can boot coreelec with some modification.
Thanks for your efforts and support to khadas users, I really appreciate.
Regards
Yasir
Too much of customization will be needed, have you tried kodi on manjaro?
Coreelec uses legacy proprietary gpu/vpu driver which may or may not work with mainline uboot.
If you still want to use it then flash Android on emmc and flash Manjaro on 1 sd card and coreelc on another sd card. Use the cards when you want to switch os.
Good luck

Hi @Spikerguy
Thanks for the suggestion. I had earlier tried kodi on linux-vim and X11 however performance was very bad. Right now i tried kodi-wayland 19.0 again on linux-rc and mesa-git and seems to be much much faster. The UI is smooth now so maybe I’ll stick with it. I just wanted to check if Coreelec is something else than a glorified KODI or not. In Manjaro, at SDDM we have option to log in directly to KODI, I think that makes it effectively a Core/Libre Elec equivalent .
