A20 quickstart

[maxwaldo]

Hello!

I have built a board using the SOM204 and it is not booting correctly.

I have:

• A20-SOM204-1G
• A20-DEBIAN-SERVER-SD
• custom carrier board (CCB)

The CCB is a derivative of the A20-SOM204-EVB and largely follows the provided schematic.
I am using the sdcard to boot from.
So far The board appears to boot but gets stuck.
Bellow is the debug output during boot:

How do I solve this issue to get it to boot to command line?

Thanks in advance.

I have connected with a uart adapter. and am trying to follow https://www.olimex.com/wiki/ArmbianHowTo Manua board configuration but get the following error:

1) Can you test using the Olimex A20-SOM204-EVB instead of your custom board and confirm if the board boots? If it boots, it is something related to the hardware; if it still doesn't boot it is probably some problem in the software (or in the A20-SOM204 board)

2) We no longer support the Armbian images. We released our own Olimage images as announced here:

https://olimex.wordpress.com/2020/04/21/olimage-mainline-linux-images-building-script-for-all-of-our-olinuxino-and-som-boards/

Can you try how it goes if you re-write the card with latest Olimage:

http://images.olimex.com/release/a20/

Best regards,

Thank you for the reply.

Please update the link here:
https://www.olimex.com/Products/SOM204/A20-SOM204-EVB/
it links to:
ftp://staging.olimex.com/Allwinner_Images/A20-OLinuXino/

which differs from the link you mentioned.

I have removed everything from the custom board. It is now simply the SOM204 connector, 220uF cap (for 5v) and sd card.
I have added console=both and verbosity=7 to then uEnv

Bellow the boot log

With other images I can even get some boot logs. What disables them in your image?

I do not have an EVB yet. I'd like to test as much as I can before that.

Best Regards

[maxwaldo]

I have noticed one thing:
=> olinuxino config info
ID:    A20-SOM204-1G Rev.K
SN:    FFFFFFFF
MAC:   02:C7:05:43:34:2F
=>

The board has Rev.C printed on the silkscreen.
Does this make a difference?

[LubOlimex]

You made a mistake in the beginning that configured the EEPROM wrong, to be specific here:

olinuxino config write 8991 k

There is no revision K of that board, nor that MAC address belongs to us.

[LubOlimex]

You need to re-configure the EEPOM with olinuxino config.

What is the exact variant of the A20-SOM204 board that you have? A20-SOM204-1G?

[maxwaldo]

It is the A20-SOM204-1G

I have reconfigured with
olinuxino config write 8991 c

Why should the wrong MAC cause the kernel not to boot?

Now I am getting some boot messages from the kernel but it stops at local-premount

I noticed that I can type into the terminal and characters are echoed back. Which is not the case when uboot doesn't boot or the kernal hangs entirely.

If I understand correctly I should see a linux login prompt when the kernel boots completely. Correct?

Is there a way I can increase verbosity further to get an idea of what local premount might be having issues with?

[maxwaldo]

I have managed to increase debug output.

[LubOlimex]

Are you sure that you have A20-SOM204-1G and not A20-SOM204-1G-M? Looking at your e-mail in our database it seems you got 2 x A20-SOM204-1G-M.

Can you try configuring in u-boot with:

olinuxino config write 10257 c

saveenv

reboot

What are the results? Publish the log again.

[maxwaldo]

Sadly no change
I have tested a few times and added the env print output as well.
after 35 seconds some power rails are disabled !?

Today I tested the same board A20-SOM204-1G-M with A20-SOM204-EVB.

Used latest Buster minimal and Buster base images from here:

http://images.olimex.com/release/a20/A20-OLinuXino-buster-minimal-20210203-221802.img.7z

http://images.olimex.com/release/a20/A20-OLinuXino-buster-base-20210203-221802.img.7z

This is the log with mininal:

This is the log with base:

I think something is wrong with your bottom board, dunno what exactly but my advice is to get A20-SOM204-EVB and test with it. It will help you determine the problem.

[maxwaldo]

I have ordered the EVB. When it arrives I will test it and the previously purchased boards and see how it goes.

I can not think of what might be wrong with my custom board.

Do you have a minimum hardware requirements document for base boards?
Maybe it is power sequencing?

[LubOlimex]

We don't have such document, but my advice is to try to replicate the base board as close as possible. A20-SOM204-EVB is open-hardware board and you can inspect the design files. An export of the schematic is here:

https://github.com/OLIMEX/SOM204/blob/master/SOM204-EVB/SOM204-EVB_Rev_B.pdf

The power supply circuit is at the bottom in the middle.

[maxwaldo]

Ok. With the EVB the boards are working (booting). So there must be an error on the custom PCB.

I am getting the reoccuring messages on the console:

and am unable to get dhcp or static address to work for eth. Is there documentation on what must be done to configure networking?
