Armbian for custom SKIPR on TwoTrees SK1

[Mechano]

Hi there!

I've tried your image on Two Trees SK1 3d printer, it has a custom OEM of the SKIPR card. 

There's  no HDMI so I can't see what happens. But putting an ethernet cable it doesn't get DHCP address. 
The card has also a wifi that I can't identify, not visible with lcpci or lsusb. 

I put a picture of the card and a schema.

I want to say that during this days I've been able to install your Armbian distribution in this mainboard of TwoTrees SK1 printer.
I've lost the use of the stock serial display, but don't mind it's crappy and can change with other solutions.

I've found into the stock firmware this two files and followed your instructions to put .dtb file in the /boot partition. 

into .dts file I've found this line:
 

compatible = "firefly,roc-rk3328-cc\0rockchip,rk3328";

 

It seems compatible with this board: https://wiki.t-firefly.com/ROC-RK3328-CC/index.html

 

I'm waiting an Artillery Sidewinder X4 Plus, It has another SKIPR-derived board. I'll try same experiment there.

I had success on installing this Armbian for SKIPR also on Artillery Sidewinder X4 Plus machine. The whole X4 lineup uses this custom SKIPR board.
In the Sidewinder X4 board there's no Ethernet port, so to configure WiFi you have 3 solutions:

• solder the Ethernet header and connect cable network just to login and configure WiFi,
• use an USB-to-Ethernet dongle compatible with Linux,
• use service USB-C port with terminal emulation. 

Always follow Maxim's instruction on take .dtb file from stock image and apply to Armbian distribution.

The Armbian has everything to configure the stock ADXL345 module provided by Artillery just add into /boot/armbianENV.txt the following lines to activate GPIO thru spidev:
 

overlays=rk3328-spi-spidev
param_spidev_spi_bus=0

I'm pretty sure the Armbian for SKIPR can be installed also onto Kingroon KP3S Pro V2 and KLP1, and Anycubic Neptune 4 family printers because they use same SKIPR custom board.
