[A20-SOM204] New A20-SOM204-1G-M module doesn't boot with latest mainline image

[Titomax]

Hi,
we just received a A20-SOM204-1G-M module, the new version without Gigabit PHY and with only the Megabit PHY mounted.
If we try to boot the SOM with the latest official Olimex mainline image:

Armbian_5.92.4_Olinuxino-a20_Ubuntu_bionic_next_5.2.21_desktop

from: ftp://staging.olimex.com/Allwinner_Images/A20-OLinuXino/1.latest_mainline_images/bionic/images/

the system loads U-BOOT but doesn't finalize the booting process.

See the starting log:

Using the latest official A20-SOM204 image based on legacy kernel:

Armbian_5.41_Olimex-som204-a20_Ubuntu_xenial_default_3.4.113_desktop

the system boots up correctly but the Megabit Ethernet appears to be disabled (ifconfig shows me only "lo" interface).

How can we test this A20-SOM204-1G-M version ?
Is an image with Megabit PHY enabled and working available to download?

Thanks in advance.


NOTE: Please update the ordering code description on the Olimex Site because following the ordering page indications A20-SOM204-1G-M should be a A20-SOM204-1G with Megabit PHY mounted "in addition" to the Gigabit one and not "instead".

The board variant is very new and not yet added, so you'd have to do some manual configuration. Get this:

http://repository.olimex.com/pool/main/l/linux-u-boot-olinuxino-a20-next/linux-u-boot-olinuxino-a20-next_5.92.5_armhf.deb

wget http://repository.olimex.com/pool/main/l/linux-u-boot-olinuxino-a20-next/linux-u-boot-olinuxino-a20-next_5.92.5_armhf.deb

mkdir aaa

dpkg -x linux-u-boot-olinuxino-a20-next_5.92.5_armhf.deb ./aaa

cd aaa/usr/lib/linux-u-boot-next-olinuxino-a20_5.92.5_armhf/

There is u-boot-sunxi-with-spl.bin inside, find it and write it to the card

dd if=u-boot-sunxi-with-spl.bin of=/dev/sdXXX bs=1k seek=8

Hi buddy, is there anyway we can automate the process while it comes to large scale partially.

Just copy the result of the steps.

we will release new A20 image with all boards (57 different versions) later this week, so there will be no need for these steps

Hi olimex,

in another post:

I warned that an important feature is wrongly missing in kernel build.
I think it is necessary to enable:

Code Select Expand

<M> X-Powers AXP20X and AXP22X AC power supply driver

in kernel configuration for having the necessary driver axp20x_ac_power enabled, otherwise we can have important issues in battery level recognition.

Thanks
