#yocto bootchooser: Cannot get state 'state'

Hi,

booting the new yocto zeus system manually by "boot mmc" works fine but default bootchooser fails with:

bootchooser: Cannot get state 'state'
Nothing bootable found on 'bootchooser'
Nothing bootable found

Building the "same" image in yocto thud works fine. The boot variables are:

* BOOT_system0_.default: 3
* BOOT_system1_.default: 3
* allow_color: 0
* autoboot_timeout: 3
* boot.default: bootchooser
boot.watchdog_timeout: 0
bootchooser.default_attempts: 3
bootchooser.default_priority: 1
bootchooser.disable_on_zero_attempts: 0
bootchooser.reset_attempts:  (list: "power-on", "all-zero")
bootchooser.reset_priorities:
bootchooser.retry: 0
* bootchooser.state_prefix: state.bootstate
* bootchooser.system0.boot: mmc
* bootchooser.system0.default_attempts: 3
* bootchooser.system0.default_priority: 20
* bootchooser.system1.boot: mmc1
* bootchooser.system1.default_attempts: 3
* bootchooser.system1.default_priority: 21
* bootchooser.targets: system0 system1
bootm.appendroot: 0
...

Thank you

Hi,

this is mainly a barebox-related question, thus I'd suggest asking it
on the barebox ML.

Looks like the state node is missing in your device tree.
Which version of barebox do you use?
And from which layer / recipe?

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[hu.schlieben]

Hi Enrico,

thank you very much for your help. 
I'm using barebox_2019.01.0-phy4-r7.0 now. In thud I used barebox_2017.12.0
The image is built using my own ims layer which depends on core-image-minimal
LAYERDEPENDS_ims-layer = "core-image-minimal openembedded-layer phytec-layer"
Its using the meta-phytec Layer and a custom layer from phytec named meta-ksp0663.
Forgot to mention that rauc is used too, which moved from 1.1 to now 1.2.
Just changed the LAYERSERIES_COMPAT to "zeus" here to check whether yocto zeus works.

Is there some info what to change in the devicetree and so on when moving to warrior/zeus?
In thud this worked.

Thank you
Regards

hu

Hi Ahmad,

thank you very much for your help.

> Are there any other error messages?
No, there is even more working than in thud where ubi0 fails but bootchooser works:
Hit m for menu or any other key to stop autoboot:    0
testing for update
ubi0: scanning is finished
ubi0 error: ubi_read_volume_table: the layout volume was not found

in zeus this looks like this:

> Can you copy the device tree snippet you use for defining state?
How/where do I find the complete devicetree? The only thing referring to barebox is this from the unchanged ksp-0663-layer:
&gpmi {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_gpmi_nand>;
        nand-on-flash-bbt;
        status = "okay";

        #address-cells = <1>;
        #size-cells = <1>;

        partition@0 {
                label = "barebox";
                reg = <0x0 0x400000>;
        };

        partition@1 {
                label = "barebox-environment";
                reg = <0x400000 0x100000>;
        };

        partition@2 {
                label = "root";
                reg = <0x500000 0x0>;
        };
};

Is there a problem because ubi works now and garbles the data in the flash?

> What does running the state command say?
barebox@Phytec phyCORE-i.MX6 Quad with NAND:/ state
registered state instances:

is empty in zeus, whereas thud returned: (backend: raw, path: /dev/eeprom0.update-eeprom)

Can you copy the device tree snippet you use for defining state?
What does running the state command say?

The difference between 'zeus' and 'thud' is mainly the barebox version that you
get from the meta-phytec layer.

We had some changes in requirements for the state node alias within the two
year, but unsure if that hits you.

Note that you can find the build dtb in your BSP's deploy dir. You could run

  fdtdump tmp/deploy/images/<machine>/<name-of-dtb>.dtb

to dump it.

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[Hans-Ulrich Schlieben]

Hi Enrico,

thank you for your help and for telling me about fdtdump. Works great.
I could not find any references to state in the device tree.
There where no references to state and bootchooser in the devicetree. 
The only references to barebox are two addresses inside the nand:
        gpmi-nand@00112000 {
...
            partition@0 {
                label = "barebox";
                reg = <0x00000000 0x00400000>;
            };
            partition@1 {
                label = "barebox-environment";
                reg = <0x00400000 0x00100000>;
            };
...
And there is a eeprom entry:
            i2c@021a8000 {
...
                eeprom@50 {
                    compatible = "atmel,24c32";
                    reg = <0x00000050>;
                };
Where to look for state in the devicetree?
Anyhow I compiled a zeus image using the old barebox version 2017.12.0 and bootchooser works again with zeus.
Interesting is that ubi fails too like in thud. So it seems as long as ubi fails state could be used or the other way around.

Here the zeus logs:

The difference between 'zeus' and 'thud' is mainly the barebox version that you get from the meta-phytec layer.

We had some changes in requirements for the state node alias within the two year, but unsure if that hits you.

Note that you can find the build dtb in your BSP's deploy dir. You could run

  fdtdump tmp/deploy/images/<machine>/<name-of-dtb>.dtb

to dump it.

Is the .config file wrong? I copied it from the barebox folder where I built barebox 2017 version.

 
> under images/ you will have the barebox images. You can get that onto your device using a SD-Card, imx-usb-loader, tftp ... etc.
When the build succeeds where or how to put the image on the sdcard?
By the way, which image is it there a lots of images in the ./image folder and there is none named imx6qdl? There are some named imx6dl and one imx6q.

Tomorrow I will try too, to build the upstream version using yocto.

Thank you so much.

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

Hi,

Did you install the SDK?

Did you run the environment script?

flex and bison seem to be missing as well.

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[Hans-Ulrich Schlieben]

Hi Robert,

there where no SDK, bison and flex missing. Now it compiled. Thanx.
There are 

Copying it onto the system and running it from the console just returned error code 132 and: 
Illegal instruction

I copied the .config file from yocto into the barebox directory. Do I have still the wrong architecture?

Perhaps I have to copy  ./images/barebox-phytec-phycard-imx6q-1gib.img onto the destination system starting at offset 0x1000 using dd.
How to copy barebox onto the sdcard? There is no setupmbr executable in ./scripts/setupmbr, just a c file and no working Makefile.

Thank you and Best Regards

hu

The barebox executable in the barebox folder, not some image. The executable starts with ELF so it should run, shouldn't it?
In the barebox README states:  The barebox image is a normal Linux executable, so it can be started  just like every other program

Wait, just running dd if= bareboximagefile of=/dev/mmcblk0 would just kill my Partitiontable in sector 0. 
When I look into the bareboximagefile I see two sections starting with something like barebox.......UUUUUUUUUUUUUUUUUUUUUUUUUU at offset 0 and offset 0x1000.
The part at 0x1000 resembles more what I see on my sdcard on offset 0x1000 so my approach would be to
dd if= bareboximagefile of=/dev/mmcblk0 bs=512 offset=8 skip=8.
What do you think?

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

Hi,

both dd copies of barebox (with and without offset) reproduced a system which no longer shows anything on the console.
Probably I setup something wrong when building barebox.

Few lines earlier, it says that the scenario in the document uses ARCH=sandbox, which indeed is an ELF executable for your host system. When building for ARCH=arm though, the resulting ELF isn't meant for running under an OS, even an ARM. Instead the necessary sections are copied out of the ELF according to a SoC-specific layout.

For testing, you can just kill your partition table, but yes eventually, you will want to copy barebox later in the image.

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[Hans-Ulrich Schlieben]

Hi Ahmad,

Thanks to your Mail I tested with barebox_2017.12.0-phy6.bb (thud used barebox_2017.12.0-phy4.bb) and this works in zeus too. 

> According to the state command output under thud, your state is stored on the EEPROM, not the NAND. Look for update-eeprom in your device tree.
> There should also be an /dev/eeprom0.update-eeprom in barebox.
That seems right, when working the eeprom is written to on each boot.
But I could not find any references to *eep* inside barebox in any layer.

> if not, try executing the drvinfo command and see if the driver has probed the EEPROM.

Booting zeus with barebox 2017 it works and looks like that:

I do not know yet how to include an upstream package like barebox 2020.01.0. Do I have to rename the old recipe or download the recipe somewhere?

Thank you and Best Regards

According to the state command output under thud, your state is stored on the EEPROM, not the NAND. Look for update-eeprom in your device tree.
There should also be an /dev/eeprom0.update-eeprom in barebox.
if not, try executing the drvinfo command and see if the driver has probed the EEPROM.

Can you also paste the full barebox output from power-on till failure?

Your board should boot normally with upstream barebox, I think.
Can you try and see if v2020.01.0 suffers from the same problem?

Cheers
Ahmad

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[Hans-Ulrich Schlieben]

Hi Ahmad,

thank you for the great help. There's a lot to learn for me here.
> Does it come from the phytec git directly? Upstream barebox has this:
The zeus image I build here includes layer meta-phytec branch zeus and a custom layer from phytec called meta-ksp0663.
On the custom layer I created a new branch zeus and just renamed the barebox and barebox-targettools bbappend files from 2017 to 2019.

You are right about the missing state in barebox2019.01. 
for barebox 2019 drvinfo just contains:
state

drvinfo for barebox 2017 says:
state 
        imx6qdl_phytec_boot_state.19
Does that mean that the driver is not loaded?

At the barebox2019 version of_dump returns: Cannot find nodepath state
At the barebox2017 version of_dump returns a full subtree for imx6qdl_phytec_boot_state and the eeprom entry for state.

Looking into the 2017 barebox sources using      find ./ -iname "imx6qdl-phytec*.dtsi"  it finds imx6qdl-phytec-state.dtsi:
This file does not exist in the 2019 barebox sources. There is only imx6ul-phytec-state.dtsi available.

Now I will try the upstream version.

Thank you very much for your help.

Best Regards

hu

Re: [yocto] #yocto bootchooser: Cannot get state 'state'

[Hans-Ulrich Schlieben]

Hi Ahmad,

i asked phytec about barebox2019 and was told that it supports imx6ul and not imx6q. I should continue to use barebox2017.
So I use Barebox2017, which works in zeus with bootchooser.

Thank you very much for your great help.

This means you have a state driver, but there was no device to bind to.

Ha! That's it. The file is in upstream barebox, so no idea why Phytec dropped it.
That's probably a question for Phytec support.
