Missing devtmpfs w/ i.MX6Q SabreSD sato-sdk image

Missing devtmpfs w/ i.MX6Q SabreSD sato-sdk image

[squirem]

Hello,

I've been trying to run a simple image, on the SabreSD devlopment board. I 
downloaded the latest version of the meta-fsl-arm BSP (dylan branch) and 
pokey-dylan package downloaded directly from the main Yocto site.

After dropping the BSP into the top level pokey directory, setting up the 
environment, and adding ACCEPT_FSL_EULA = "1" to local.conf, I ran the hob 
GUI. From there I added the meta-fsl-arm BSP, selected the imx6qsabresd 
machine, then selected core-image-sato-sdk base image and just let that 
built.

When that was finished I begin copying over the bootloader, kernel, and 
rootfs in the following order:
sudo dd if=u-boot.imx of=/dev/sdc bs=512 skip=0 seek=2 conv=fsync
sudo dd if=uImage of=/dev/sdc bs=512 skip=0 seek=2048 conv=fsync
sudo fdisk /dev/sdc (made new primary partition at sector 16384)
sudo mkfs.ext4 /dev/sdc1
sudo tar --numeric-owner -xzvf /home/user/Desktop/poky-dylan-
9.0.0/build/tmp/deploy/images/core-image-sato-sdk-imx6qsabresd.tar.gz

I then put in the SD card into the board, booted it, and observed the output 
from the debug port. It loads up the kernel and filesystem, but it 
eventually fails. This is the output I was left with before it stopped:

Waiting for root device /dev/mmcblk1p1...

Any help would be appreciate, thanks.

Are you sure you're using dylan?

Thanks for the response.

I'm certain I'm using the latest release of poky, downloaded straight from 
the Yocto site: https://www.yoctoproject.org/download/yocto-project-14-poky-
900

However, I can't really remember when it was I downloaded the meta-fsl-arm 
BSP, but I did download it from here: https://github.com/Freescale/meta-fsl-
arm/tree/dylan

I will start from scratch and make an update on the results.

I've rebuilt the image using the pokey-dylan builder from the Yocto site and 
the meta-fsl-arm BSP provided from here:

https://github.com/Freescale/meta-fsl-arm/tree/dylan

I got the same errors claiming that devtmpfs was missing. Any advice advice 
on how I can handle the issue?

I didn't build dylan (community) branch for a while; Daiane, did you
build and tested dylan lately?

[Luo Zhenhua-B19537]

Seems like CONFIG_DEVTMPFS and CONFIG_DEVTMPFS_MOUNT are not enabled in Kernel. 

Please check if the two options are enabled.

I'm using linux-imx-3.0.35-r31.14 for the imx6qsabresd machine with the core-
image-sato-sdk image. I looked into the following file:

meta-fsl-arm-dylan/recipes-kernel/linux/linux-imx-3.0.35/mx6q/defconfig

It seems the following options were enabled:
CONFIG_DEVTMPFS=y        (line 94)
CONFIG_DEVTMPFS_MOUNT=y  (line 95)

Let me bitbake and test core-image-sato-sdk.


Do you know your board revision and chip TO?

I see the following labels on the board:

> Let me bitbake and test core-image-sato-sdk.
I suspect I may be doing something wrong, the core-image-sato-sdk will 
probably work for you. I'm going to try and build the 
image directly through bitbake, instead of the hob gui, and see what 
happens. This is my build configuration:

Build Configuration:
BB_VERSION        = "1.18.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "Fedora-16"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "imx6qsabresd"
DISTRO            = "poky"
DISTRO_VERSION    = "1.4"
TUNE_FEATURES     = "armv7a vfp neon"
TARGET_FPU        = "vfp-neon"
meta              
meta-yocto        
meta-yocto-bsp    
meta-hob          
meta-fsl-arm-dylan = "<unknown>:<unknown>"

Here is how the meta-fsl-arm layer was added in my bblayers.conf file:
#added by bitbake
BBLAYERS = "/home/squirem/Desktop/poky-dylan-9.0.0/meta \
/home/squirem/Desktop/poky-dylan-9.0.0/meta-yocto \
/home/squirem/Desktop/poky-dylan-9.0.0/meta-yocto-bsp \
/home/squirem/Desktop/poky-dylan-9.0.0/meta-hob \
/home/squirem/Desktop/poky-dylan-9.0.0/meta-fsl-arm-dylan"

May I ask what steps you take in building the image?

Sure:

I follow the steps from
https://github.com/Freescale/fsl-community-bsp-platform


$ ./repo init -u https://github.com/Freescale/fsl-community-bsp-platform 
-b dylan
$ ./repo sync
$ source ./setup-environment build
$ MACHINE="imx6qsabresd" bitbake core-image-minimal


I'm not used with HOB, in fact...

My image is still baking. I want to make sure I cannot (or can)

Oh; HOB might be doing something messy here.

Please confirm it does work using bitbake so I can check it.

No luck, it doesn't seem the issue is related to hob. I'll try the steps 
Daiane linked to on the fsl-community-bsp-platform github page and see how 
that works out.

Thank you. I'm in the process of trying this myself. I have a feeling the 
instructions you linked to will work. I'll update you on the results.

Hello Daiane,
The sdcard image generated by poky seems to work. However, I first tried 
dd'ing u-boot, the kernel, and rootfs individually and I received the 
"missing devtmpfs" error. This means the issue has something to do with how I 
copied the images to the SD card. I must, how exactly is that SD card image 
put together?

Exactly, you can find it here:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/classes/image_types_fsl.bbclass

From your log

it seems your rootfs was properly mounted. However I don't see those
ext2/ext3 errors on my log:

Would if be some partition table issue?

I believe so. I notice that the SD card image generated by poky contains two 
partitions: the boot partition and the root fileystem partition, while my SD 
card only contained a single partion.

This was my disk layout:
Sectors 0-1:        Protected
Sectors 2-2047:     u-boot
Sectors 2048-16385: uImage
Sectors 16384-...:  First partition + start of root fileysystem

I was basically following the same procedures as when I was using LTIB, which 
apparently does not work here.

I appreciate the help.

Best regards,
Saddam Quirem

The difference would be only u-boot default bootenv configuration. If
you're setting everything
by hand, it would be easy to you to modify your u-boot parameters.


I'm still working on bitbake core-image-sato-sdk. I faced a build
error in one package (perl or something like that)
so I was not able to test it yet.

It seems the issue was with how I set up my partitions. The instructions 
Daiane linked to worked.

I appreciate the help.

You should be able to just:

$ sudo dd if=tmp/deploy/images/core-image-minimal-imx6qsabresd.sdcard /dev/sdc

and have a working sdcard without having to do all that other stuff.
