Mainline Linux LTS 5.4.x issues (ethernet, mmc, drm)

ddevault · January 2020

Hello! I'm working on getting Alpine Linux running on this device. I'm using the mainline linux-lts kernel 5.4.12, with no patches: .
I've prepared which, when flashed to a USB stick, comes up no sweat and boots to a shell normally. The issues are then apparent:

I have no eMMC devices in /dev
eth0 exists, but attempting to bring it up gives "ip: ioctl 0x8914 failed: No such device"
The display has bizzare issues where many new pixels won't be written to the display until a few redraws later, using the tty0 console.

I've tried to boot up the official Armbian mainline images for comparison, but I can't get those past u-Boot (FDT_ERR_BADMAGIC). Can anyone with a working 5.x config share it, review mine for errors, or boot up and help troubleshoot my ISO?

It's not necessarily straightforward to unpick, but LibreELEC has a build that works using 5.something. Depending one which things you want to lift, it might be useful

I've had armbian working fine on 5.3 and now 5.4 using their images. Not sure what your uboot issue is, have you updated it to the r5 release here? http://share.loverpi.com/board/libre-computer-project/libre-computer-board/aml-s805x-ac/firmware/

With that uboot, you can just dd armbian directly onto the eMMC via USB.

I'm using Armbian Bionic with Linux 5.4.6-meson64 right now on La Frite without issue. With R5 U-boot. Super stable. Waiting patiently for the official retropie/lakka images to test.

Just upgraded to Linux 5.4.12-meson64 on Armbian Bionic

Hi, i have problem with newest kernel from github. I make kernel that way:

0. sudo apt-get install git gcc-aarch64-linux-gnu (+ standard toolchain for kernel build procedure)
1. git clone --depth=1 https://github.com/libre-computer-project/libretech-linux.git --branch v5.4/libretech-master-stable-build

2. cd libretech-linux/

3. make ARCH=arm64 defconfig
4. make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 -j 4 deb-pkg amlogic/meson-gxl-s805x-libretech-ac.dtb

here is produced kernel withuout dbg package

also i am prepared kernel with additional included drivers for dvb usb devices from usb v1 and usb v2 subpage by make menuconfig plus three patches for my terratec cinergy s2 box :

But unfortunelly above kernels fails when i install on ubuntu by "dpkg -i" coommand on images from here

Any suggestion where is the problem ????

Clock framework was re-worked between 4.19 and 5.4. Try to copy the new dtb to /boot/EFI/libre-computer/aml-s805x-ac/platform.dtb

ok thanks, copy the new dtb to /boot/EFI/libre-computer/aml-s805x-ac/platform.dtb
i compiled today above kernel with extra usb drivers :usb:sound,dvb,wifi,bt,webcam+fix terratec cinergy s2 box
