Hello @aXe_111
Could you please use OOWOW to install the test image to check the sd card again?
Test image: vim4-ubuntu-22.04-server-linux-5.4-fenix-1.0.11-220615-emmc-develop-test.raw.img.xz
Installed it. First observation the image is unstable in terms of ssh connection.
Mount is now successfull with 64G SanDisk Extreme A2
My script is now running aswell:

The only cards really running the test are the SanDisk cards. Especially the SDHC (16GB) Cards don’t work in the VIM4
OK, our sales will contact you later.
Exact same thing just happened to me on my VIM1S.
I bought it on Amazon and requested a replacement.
I use KIOXIA EXCERIA G2, SanDisk Ultla A1, SanDisk SanDisk Extreme A2.
KIOXA is not recognzed, and SanDisk Ultra cannot boot it.
I can boot Ubuntu with SanDisk Extreme A2, but the filesystem become read-only soon.
dmesg show same error in this topic.
So I do not believe that it is possible to boot from an SD card other than the SanDisk Extreme PRO A2 that has been confirmed to work.
In addition, I checked two VIM4 with SanDisk Extreme A2.
Serial: 25A00009B5, 25A00009BA
I got same error. So this is not initial error.
Therefore I think that there are some conditions for SD cards used in VIM4.
Could you tell me which image you used ?
Thank you for the reply.
I use generic/vim4-ubuntu-22.04-gnome-linux-5.4-fenix-1.4-221229.img.xz.
The steps I have taken are as follows:
-
Erace eMMC
Normaly SD card is primaly boot device, so it maybe unnecessary. -
Write Image to SD card with Etcher refer to VIM4 Install OS into External Storage [Khadas Docs]
-
Connect SD card
-
Connect HDMI carble for display.
-
Connect USB-C carble to power.
I bought the SanDisk Extreme PRO A2, so I try to boot VIM4 tonight.
I can boot VIM4 with the SanDisk Extreme PRO A2, but filesystem become read-only soon.

I have some improvments to the SD cards. I checked SanDisk Extreme PRO A2 and SanDisk Ultra A1 on my side, both work well.
Could you also check this test image ? https://dl.khadas.com/.test/vim4-ubuntu-22.04-gnome-linux-5.4-fenix-1.4.2-230307-develop.img.xz
@numbqq
I can boot with the test image.
I use the SanDisk Extreme PRO A2.
VIM4 is fine.
What kind of magic did you use?
Okay, this fix will be in next release.
Hello @numbqq,
I have a new Khadas VIM4 (just got it) and try to use it with SanDisk Extreme Pro A2 128GB sd card. I downloaded the test image you linked, but the VIM4 seems to be stuck in boot loop (white light comes up, fan spins up, both stops, repeat).
Thanks for your help.
Make sure your USB cable is actually rated for 5 amps and you must have that board on a stiff supply. It is best to use their official power supply or one that is same or better specs.
I replaced my power supply (HP docking station) even though it was rated for 19.5V - 6A with a normal USB-C power supply and it seems to be working fine. Thanks!
