Hello,
Are you going to upload new version of Manjaro for VIM3 (VIM3 Pro)?
Or have you dropped support?
I don`t see any updates since version 20.06 of 15 of June at osdn.net although
as far as I understand the general project is developing and version 20.10 already
exists.
Thank you for any kind of information.
Have always supported it just didnāt create new images as there was not much of update but as panfrost is ready we plan to have a vim3 image for 20.12 release.
Even with old image you can just update packages and it will be on latest packages.
I have been hosting the newer image on my server as osdn storage was full.

Thanks for asking.

Thank you so much for your reply and for the links.
Id like to try installing latest version of Manjaro on NVME SSD disk connected with new Khadas M2X board. Ive flashed Krescue uboot into SPI so I hope after switching to SPI boot in Krescue
it will detect and load Manjaro installation from NVME SSD.
Nice, that reminds me of ny m2x in my drawer but need nvme for that test. Currently cannot afford it maybe later in the future.
Do let me know how the test goes, I am not sure if M2x is upstreamed or part of linux kernel yet.
Good luck.

Unfortunately you were absolutely right. It doesnāt work. Neither AML mainline uboot, nor Krescue
SPI uboot by Hyphop can detect and load anything from NVME M.2 SSD.
And only stock Android and VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_SD-USB_V20191231 which uses legacy uboot or legacy kernel (I may be wrong) could detect it as an external drive. Unfortunately Manjaro 20.06 and VIM3_Ubuntu-gnome-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530 either canāt see it and I donāt have other Linux distros installed into EMMC to test.
This is an Ubuntu-xfce-bionic_Linux-4.9 screenshot:
And this screenshot taken from Manjaro v.20.06
Unfortunately I couldnāt test it in other Linux distros.
I really hope that it will be made in the future builds because it really makes sense to have
an opportunity to load Linux from SSD disk taking into note its tremendous read/write speed comparing with SD card or USB.
hahaha, Thank you for the information, you saved my time 
@hyphop @Frank do you have any patch for mainline kernel that is needed to get m2 support ?
If yes then please do share it as I have bought an M2 extension board and have never put it to test so far. I will patch it so we can do some testing on it.
Thank you.
@Spikerguy Hello , I have tested PCIE, it works normally, M2X is just a hardware connection, there is no related patch
Neither AML mainline uboot, nor Krescue
SPI uboot by Hyphop can detect and load anything from NVME M.2 SSD.
some correct info
- mainline uboot for amlogic still not support nvme
- linux kernel support OK
- krescue use same mainline linux kernel and same can use nvme without problem
PS: in any case its not problem - just make boot partition with kernel to emmc
and next rootfs and other partition can load from nvme
Hello hyphop
just make boot partition with kernel to emmc
and next rootfs and other partition can load from nvme
As Iād like to keep Android in my emmc Iām wondering is it possible to start Linux from NVME SSD disk like from USB or SDCard?
Or to make Linux Boot partition with kernel along with Android partition like with CoreElec installation in emmc allowing switching between Android and CoreElec?
Is there any possible workaround?
If you check my screenshot of Gparted made in Ubuntu-xfce-bionic_Linux-4.9 which detects SSD as an external drive (3 posts above) you will see that there are Boot Manjaro partition and Rootfs Manjaro flashed on nvme0n1 which is my SSD but nothing can load and start directly from this SSD
yes for example easiest way for u
boot uboot and linux kernel from SD card and continue load rootfs and other from nvme already
can you write a short manual of how to make it for noob users like me? 
I searched the forum and found several topics about nvme ssd issues.
For instance Iāve found this:
I confirmed that I had set the correct portmode in Krescue. I have successfully partitioned and formatted the drive as ext4 in Ubuntu bionic with 4.9 kernel (I understand that the NVME driver may have been disabled in 5.7 due to stability issues).
M2X board with 1TB NVME running Android Pie or CoreElec
So Iām wondering is there any way to enable NVME support in latest kernels and future Manjaro builds at least to have an ability to mount nvme ssd as external drive. Now it doesnāt work
Sounds good.
I need an nvme drive to test. 
I think the module is enabled. Unless it is something other than standard config.
@hyphop can you confirm which config is needed in latest kernel for m2 port to work?

@Spikerguy Hello,
Iāve managed to mount ssd on VIM3_Ubuntu-server-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530 after adding this line to env.txt of boot:
# User kernel args
# Add customer kernel args here
user_kernel_args=nvme_core.default_ps_max_latency_us=200
so actually pcie is supported by latest kernels but possibly some wrong config settings prevented ssd from detecting by the board.
I think we could discuss it.

Thatās good to hear. Where did you get this argument from?
You should try the same with Manjaro and add it to extlinux.conf

I searched many topics related to nvme boot issues and should admit that there is not so much information.
Iāve found some in Russian and Western Internet resources:
which were similar to my errors got in Ubuntu 5.7:

Iām going to try adding the line to extlinux.conf as you advised
Should I make it that way:

Or to write it additionally in separate line?
Iām not sure that it will help because unlike two Ubuntu distros I used Manjaro unfortunately gives no outputs to nvme related commands like lspci or dmesg | grep -i nvme

First i need to understand which config is needed in kernel config to make the linux kernel detect the nvme drive once we can see the drive then we can look into the booting side of it.
Update: Bought an nvme 256gb by kingston a2000 and it doesnāt seem to detect on Manjaro even when using mainline kernel.
@hyphop or @frank can you share which kernel config is needed for m2 to work on mainline?
As you said the dtb have m2 support already then please share what module is needed to get it to work.
Thanks.
Update: I found something on Kernel side which I remember now that USB3 and M2 PCIE is muxed.
So we need to enable kbi or something to make it use pcie instead of the usb3 connector.
Or patch this dts by uncommented those lines.
I also see a patch for pcie in fenix git. @numbqq can you help me understand why 0092-VIM3-hack-for-PCIe.patch is needed?

The PCIe/USB3 switch can be accessed from the command line as shown in Khadas Docs.

Thanks @RDFTKV This helped but not without a custom dtb with pcie enabled.
Finally I can see it visible in lsblk
What is needed:
- Enable kbi to PCIE Mode using this guide.
- Change dtb to pcie enabled version which I build, Will share the dtb here later.
meson-g12b-a311d-khadas-vim3-pcie.dtb
Try this dtb and also change it to pcie using uboot kbi steps.
There seems to be some problem when using NVME,
When NVME is being used the screen would keep flickering and glitching all the time. without the nvme it will not do this.
