on other devices, how does the disk behave?
I’m on Linux Khadas 5.5.0-rc2

I use the disc in a USB key. On my PC, it works well. But I can’t manage to use via USB on VIM3 and jetson nano.
ok, can you temporarily download Android and check? you will need to switch the trigger for nvme in the settings too
has been told before,
and has been switched, seems that there is still no luck
specifically about Android, he said nothing.
in any case, you need to check on different OS to exclude incompatibility of firmware
I am sorry, I was referring to this,
Oh Man, we have a bit of a communication problem ,
Hope that doesn’t become a problem
the main thing that ronron understood!
That’s about ok, Atleast he could understand us both
Wait a second, @ronron that firmware has PCIe disabled due to bugs
Its obvious it doesn’t work. try a newer firmware
Hello, Since you are using an SD/USB firmware, why not give Focal 5.7 version a go.
Yes use that it is the latest firmware with proper PCIe support,
here is a reference to where I know about it
I hope that solves the problem ,and sums it up , Good day !
Well, actually I hinted at it
Oops, It happened again
no, we just have a great desire to help
Yes, I do agree
My ssd in androidTV is detected. Don’t work, but detected .
So gpu not ready and nvme ssd so not ready on ubuntu
wait, how to understand this?
try changing the file system!
as a rule, if an android recognizes a disk but cannot read it, it usually suggests formatting it and creating the correct file system!
You can see the notification in the curtain!
And one more thing, what is your power supply? since the requirements for the board, it is up to 12 Volts 3 Amperes, otherwise peripheral problems may occur!!!
I has installed 4.9 from sd-rescue

SSD work and write/read is OK.
With VIM3_Ubuntu-server-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530, I don’t have keyboard and network. So I don’t know
I will be able to start manufacturing my expansion card.
I have 12V and 2A
Thanks for asking Those Questions @Vladimir.v.v I forgot to ask about Formatting and Power supply,
