T2-OLinuXino-LIME2-e16Gs16M-IND does not boot our image.

[fchk]

Hello world;

We started two years ago building a product with the A20/T2 LIME2 and have since then shipped several units with a custom image based on A20-OLinuXino-bullseye-minimal-20220928-143706.img. We have used A20-OLinuXino-LIME2-e16Gs16M and T2-OLinuXino-LIME2-e8Gs16M-IND. Recently we bought some T2-OLinuXino-LIME2-e16Gs16M-IND, and they won't boot our image. They do, however, boot the most recent image A20-OLinuXino-bullseye-minimal-20231106-081613.img

Short:
A20-OLinuXino-LIME2-e16Gs16M with A20-...-20220928-143706.img: boots fine
T2-OLinuXino-LIME2-e8Gs16M-IND with A20-...-20220928-143706.img: boots fine
T2-OLinuXino-LIME2-e16Gs16M-IND with A20-...-20220928-143706.img: error
All boards with A20-...-20231106-081613.img: boot fine.

We need to stay on our current codebase since this is what is tested and certified by the customer. So what exactly is our problem?

Thanks.

[LubOlimex]

It seems the ID for that board is missing from u-boot. See where failed boots says:

ID:     Rev.L1

where successful boot says:

ID:    T2-OLinuXino-LIME2-e16Gs16M-IND Rev.L1

The issue is that probably in the old image there was no ID for that version of the board (since that variant wasn't manufactured yet at that time, so no way to have ID).

[att2]

And how to fix this ?

[LubOlimex]

The Linux image needs to have ID entry for T2-OLinuXino-LIME2-e16Gs16M-IND - older images have no ID entry for it simply because that variant fo the board didn't exist at that time.

Either add the entry and settings for ID 11444 or use latest official Olimage image (where such entry was added).

Edit: A little extra help if you wish to modify the u-boot of the image you already use. You can find how the ID entries that are added in u-boot here:

https://github.com/OLIMEX/u-boot-olinuxino/blob/release-20240312/board/olimex/common/boards.c

Find in the file 11444 to see what is the config for T2-OLinuXino-LIME-e16Gs16M-IND.

Maybe just to confim that is the issue, from the drop down menu check the older release (that you used in your own image) and see if there is entry for T2-OLinuXino-LIME2-e16Gs16M-IND but I am 99% sure there shouldn't be one or it was different.

Hi Lub,
we are having the same problem.
Our product uses an old Armbian-based image (we cannot absolutely modify it).
Using old SOMs "T2-SOM204-1GS16ME8G-MC-I" all is working well but trying to use new P/N: "T2-SOM204-1GS16ME16G-MC-I" at startup the system cannot boot.

I understand that the solution is using an updated U-boot.

Can I make the modification to our Armbian image directly with "dd" Linux command ?

I tried this procedure:

1) Flash latest Olinuxino image on an SD
2) Use the following "dd" command to extract U-boot from that image:

Code Select Expand

#dd if=/dev/sdc of=/path/u-boot-sunxi-with-spl.bin bs=1024 skip=8 count=$((1024-8))

3) Use the following command to overwrite old U-boot on the Armbian image

Code Select Expand

#dd if=/path/u-boot-sunxi-with-spl.bin of=/dev/sdc bs=1024 seek=8
When I try to use the new custom image with the new U-boot on it the system hangs after printing this:

CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
Loading configuration from EEPROM: OK
Verifying data: OK
Trying to boot from MMC1

I'm doing something not allowed ? How can I exchange U-boot version in the right way ?

Thanks in advance for your support.

[LubOlimex]

It doesn't boot from the SD card? Or it doesn't boot form the eMMC?

What exactly is the boot log of a failed boot?

Notice that your issue is different form the issue of the poster above you. He used old Olimage, you use entirely different image (Armbian).

Armbian Linux has nothing to do with Olimage Linux.

I don't think there is ID recognition at all in Armbian which means that you'd have to configure the u-boot manually for the 16Gb eMMC.

[Titomax]

Hi Lub,
the system doesn't boot from the SD card.
The same SD card boots from the EVB but using the previous T2 board with 8GB eMMC.

The Armbian image we are using is using ID recognition and I verified that the ID for the T2 16 GB is missing.

We cannot touch the Armbian image. How can I make U-boot start correctly ?

Can I modify the EEPROM so that U-boot can recognize the board as a different one already managed ?
If I change the ID so the U-boot see the board as a "A20-SOM204-1Gs16Me16G-MC - 8958" ? May I encounter compatibility problem ?

See the output from the U-boot console using "olinuxino config list" command:

Hi Lub,
just an update.

I modified EEPROM data from U-boot console using the command:

Code Select Expand

olinuxino config write 8958 c 11112222 aa:bb:cc:dd:ee:ff
I set the info from my specified SOM module changing only the ID from 11462 to 8958 so that the SOM is now identified as "A20-SOM204-1Gs16Me16G-MC".

Now all is working as expected.
I put a system under test to see if malfunctions appear.

What kind of modifications are present on the U-boot or image switching from COMMERCIAL to INDUSTRIAL grade ID ?
Are there any driver specific modifications to support different grade IC ?

Please let me know if this approach can be used without encountering stability issues.

[LubOlimex]

The problem is visible in the log - the board boot defaults to some generic config - this is pretty major problem.

The fast way to boot would probably be to try a workaround then, put some board that is nearly identical via the u-boot. Set is like the older board "T2-SOM204-1Gs16Me8G-MC-I". Do he following:

- run your Armbian image but interrupt u-boot

- type:

olinuxino config write 10234 C2 0002AC2C 30:1F:9A:D1:67:37

then type:

saveenv

then

reset

See if it boots.

[LubOlimex]

Better try with the ID of T2-SOM204-1Gs16Me8G-MC-I.

[Titomax]

Better try with the ID of T2-SOM204-1Gs16Me8G-MC-I.

Ok, I didn't use "T2-SOM204-1Gs16Me8G-MC-I" because I thought that wasn't possible specify a configuration with a different hardware mounted.

Let's me try also with ID you suggested.

I'll give you a feedback.

[Titomax]

Hi Lub,
I confirm that also using ID "10234" from "T2-SOM204-1Gs16Me8G-MC-I" all is working as expected.

As workaround for my issue I'll start using this procedure.

Thank you for your support.
