Make sure the ethernet cable of the onboard X5000 ethernet adapter is unplugged.
sudo ifconfig eht0 down (enter)
sudo ifconfig eht0 up (enter)
Now plug in a cable in the onboard X5000 ethernet adapter.
The adapter gets an Ip adress through DHCP and see if it works.
I tested it today. Unfortunately I can't activate eth0 after
sudo ifconfig eth0 down.
sudo ifconfig eth0 up

Hi All,
Here is the
RC4 of kernel
5.4 for testing.
New:
Download:
linux-image-5.4-rc4-X1000_X5000.tar.gz
Screenshot of ubuntu MATE 16.04.6 LTS with the
RC4 of kernel
5.4 on an A-EON AmigaOne X5000/40:
Please test the kernels.
Thanks,
Christian

Do you not have an Eth0 when using ifconfig ?

Hi Skateman,
Many thanks for testing the RC4!
I have the same ifconfig output but after deactivating (down) I can’t activate the interfaces anymore.
Cheers,
Christian

Hi All,
I released the
RC4-2 of kernel
5.4 because of a new patch for solving the onboard SD card issues today.
New:
X5000/20 and X5000/40: coherent_cache patch by Michael Ellerman for solving the issue with the onboard SD card.
He wrote:
For historical reasons powerpc kernels are built with hard wired knowledge of whether or not DMA accesses are cache coherent. Additionally device trees on powerpc do not typically support the dma-coherent property.
So when we know that DMA is coherent, override arch_of_dma_is_coherent() to tell the drivers/of code that all devices are coherent regardless of whether they have a dma-coherent property.
Benjamin Herrenschmidt wrote:
Fundamentally when you set CONFIG_NOT_COHERENT_CACHE you tell the kernel that your processor isn't snooping the bus for DMA accesses colliding with the caches. Thus SW has to explicitly maintain cache coherency around DMA operations by invalidating or flushing the cache accordingly and by keeping pool(s) of non-cachable memory around to use for the consistent allocator. This slows things down.

From where did you succeed to get a new U-boot version??? And what version is it...? At least my X5000 dealer has not succeeded to get any update from A-Eon!
