I hope this never happens. It was still not enough to put this demonic operating system on an excellent board.

Meanwhile, we had a big review of a single-board PC, the M4 is in the review. And its characteristics are not even bad, compared to competitors.
 

I hope this never happens. It was still not enough to put this demonic operating system on an excellent board.

This is a new hat - PCIe to USB 3.0 x4 HAT LINK

The long-awaited fee on the M4, in the form of a plate.
NVME SSD Adapter for M4 No price yet, write to WiKi
 

Here's some photos of my M4 with SATA hat and 4 SSD's in a drive case - all working beautifully

Crucial MX500 1000GB 2.5

No issues with SATA hat on Armbian. Boot still uses the SD to get going, then everything else runs from a drive on SATA. Install to SD or EMMC and then use the Armbian utility to install to SATA.
 
I'm using Friendly OS currently as it supports hardware video acceleration in Chrome, where Armbian does not. The Bluetooth and analogue sound are also less hassle. BUT, it does not move to SATA - or I have not found out how. 
 
The power button works in both OS. This will be handy if you want a "power failure organised shutdown". 3 pin CPU power management devices exist to do this. I have on Class D amps to stop power down thumps. The shutdown speed of this board is probably less than 1/2 sec, so probably do-able.  e.g. MCP121 plus a few resistors.
 
Poor laptop snuggled in it's bag the last few weeks as the M4 is doing everything I want right now.  :-)

Thank you for informing me that fact.
you know, the money for me is limited as well so we chose this chip.
Of course we understand it can fail during the flight.
It is going to be like "Welcome on board. You can enjoy playing some games running on RK3399 during our flight" haha 

Only FriendyArm dist(Desktop, Core) from 201812 support 13/4MPix cameras for now.
 
in armbian(with 4.4 kernel) you need:
 - build and install a kernel with ov13xx driver(it's disabled now, also it missed a camera config) and rockchip ISP driver enabled;
 - install rkisp gstreamer driver to get accelerated access to Rk3399 ISP(Image Signal Processor - where CSI cameras connected, );
 - maybe few more things;
 
new 4.20 kernel(you can install it from armbian-config) create a /dev/video0 - it's not correct device for camera.
 
in next few days I will make some test, so will share some info here

of course, bro ,just a little trick.

there is the download dir.
And It has many imgs.
if you find the 4.20 can work.
I would be grateful for that.
