[Next LTS kernel 4.19.y Allwinner A10, A20, A64, H2+, H3, H5, H6 debugging party]

Hi,

 

I've just tested my pcDuino3 and pcDuino3nano boards. I compiled Ubuntu 18.04, Dev kernel as headless and desktop for nano and non-nano) with vagrant.

Interestingly, the nano "flavour" seems to work fine on both boards (4.20.7-sunxi Kernel , HDMI, USB, Nework on pcDunino nano (except for the not-working network on the pcDuino3 board, obviously).

But I cannot boot the non-nano version on either board. I connected a serial output and it hangs at:

 

U-Boot 2018.11-armbian (Feb 07 2019 - 13:21:03 +0000) Allwinner Technology

CPU:   Allwinner A20 (SUN7I)
Model: LinkSprite pcDuino3
I2C:   ready
DRAM:  1 GiB
MMC: 

 

Tried different cards, different PSUs, no change.

[Lime2 mainline kernel with Debian 9 (stretch) becomes unresponsive (forced reboot required)]

I can confirm the unstable behaviour described by denox for pcDuino 3 and pcDuino 3 nano with Armbian 5.37 / 5.38 as well.  The same goes for the dev kernel 4.15 RC9. Maximum uptime was 2 days, but 5 to 20 hours was more common. 

 

My installation is pretty basic: Armbian Xenial, Desktop disabled, mariaDB, Apache2, owncloud. 

 

Last stable kernel seems to be 4.13.16 (Armbian 5.35) for both boards: uptime 6 days and counting.
