Sunchip_SDK-758 A20 TV BOX

[nexdom nexdom]

Hello Community!!!

I got this device https://linux-sunxi.org/Sunchip_SDK-758
I’m trying to boot armbian Armbian_23.11.1_Cubietruck_jammy_current_6.1.63_xfce_desktop.img

Burned image with balena etcher, phoenixcard( invalid image), win32diskimager, and DD but same result…board won’t boot complaining about missing Ethernet

If I insert the sd card and an usb key burned both with same image the board boots correctly.

Only caveat is I need that usb because it’s the only one working so I can’t log in with keyboard and ethernet seems not to work properly so i can't SSH into it

Is there a way to make it boot only on sdcard?

additional info---->actually board is flashed with ubuntuone (kernel 3.4.709) it boots properly from nand

i found this .FEX file here https://github.com/ade-ma/A20Notes

might it be helpful?

.....i'm getting crazy burning dozens of images finding the right one

thnx in advance
