Hello TI,

We are using Am62p-lp borad,

Os- tisdk-debian-bookworm-rt-am62pxx-evm 09.02 version

    Hi,

    Docker should be already supported in the SDK. Let me check on this tomorrow and get back to you.

    Hi Bin Liu,

    we tried before also in debian image,at the time we faced issues while installing .you can refer this thread https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1390261/tmds64evm-docker-error-related-to-kernel-build/5365218?tisearch=e2e-sitesearch&keymatch=%25252520user%2525253A597546#5365218

    In above thread,ti was created a issue record id SITSW-4864 . i verified from the release notes  of trixie,still it is there in known issues which are not resolved in the current debian release (if iam not wrong).

    BR,

    Raj.

    Hi Raj,

    Thanks for providing the thread of the previous communication on this issue. I checked on the internal record SITSW-4864, it is not resolved in SDK10.0 due to other dependencies. I am checking with the dev team to see if it can be resolved in SDK10.1.

    Meanwhile, I am trying to see if you can rebuild the kernel with corresponding kernel options enabled to get docker working - in the previous thread, it seems indicating the Docker does not only requires CONFIG_CGROUP_BPF=y, but also CONFIG_EXT4_FS_SECURITY=y and CONFIG_EXT3_FS_SECURITY=y. Have you tried to enable these options to see if these are the only missing kernel options?

    Hi Bin,

    There are two things that we found,

    1.  I have installed docker in debian bookworm 09.02 (which is previous release). In this version all the above mentioned flags are enabled so we have successfully installed the docker and created the docker container however, we cannot start the docker due to the error as reported above.

    2. In the lastest SDK release (debian trixie(v 10.0)), we are encountering an error related to release file ('docker release file not found') as mentioned in previous thread.

    Can you please provide steps on how to rebuild the kernel with required flags? Since we are blocked in both the ways any help would be really appreciated.

    Thank you.

    Hi Raj,

    It seems still some kernel configs are missing in debian 09 and 10 for docker.

    Have you got docker fully working in Yocto based SDK10? If so, can take its /proc/config.gz and use it as .config for debian kernel to see it will make docker to work in debian?

    Hi Bin,

    Just a small add on. we have to change some flag in ti_rt.config also to avoid overwrite to these flag.

    I am not familiar with EtherCAT, but it seems "ec_master" is a off-tree kernel module from EtherCAT package? Did you recompile the ec_master module after you recompiled the kernel?

  • 0 in reply to Bin Liu
    Genius 3209 points

    Bin:

     I believe EC Master is an aconis technologies product. I had (+) Daolin Qiu's Profile - Daolin Qiu - TI E2E support forums check on this; I am also certain +) Thomas Leyrer's Profile - Thomas Leyrer - TI E2E support forums   in the Industrial Automation Lab in Germany knows acontis fairly well.

    TI__Guru**** 153631 points

    Jim, thanks for the details.

    The bottom line is that whenever the kernel is modified and recompiled, any off-tree kernel module should be recompiled too against this new kernel build, otherwise, the kernel module might failed to load, because of the kernel signature mismatch.

    Hi Bin,
    You are correct we rebuild the ethercat and its successfully rebuild and ethercat.ko file also created but the problem is since I deleted the lib/modules for old kernel and paste the new kernel modules. while building ethercat it automatically creating the folder of old kernel name and pasting the ethercat folder into it. so after that i manually copy that folder inside the new kernel but even if its not working.

    Let me tell you one thing we not giving any path where to install ethercat but i should automatically take the current kernel.

    Can you tell me the steps where i can build the kernel image with same old kernel name.
    I am thing there are even if some dependencies are there with the old kernel and new.

    One last thing to add on we are using the same old linux-header(/usr/src/linux**) while ethercat install its taking the old header and building it.

    Debashis

    In this ethercat build thread also they are asking for it.

    Hi Bin,

    After reading some document i came to know that when we rebuild and kernel the linux headers are also required to but in our case we just copy the linux header from old kernel and renamed it.

    Can you tell me how can we get the headers for new kernel

    Hi Bin,

    I have went through the Makefile of Linux source code and I found how to build Linux headers. Can you tell me is it the right process.

    Fullscreen
    1
    sudo make ARCH=arm64 INSTALL_HDR_PATH=/media/debashis/rootfs/usr/src/linux-headers-6.6.32-rt32-g66c58b6a4a36 headers_install
    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX


    Its only created the include folder rest all folder i copied from linux-source kernel code from ti after every thing is build.

    files and folders which are copied:
    Makefile  Module.symvers  arch  scripts  .config


    Is it the right process to generate the linux header for new build kernel ?

    Debashis

    TI__Guru**** 153631 points

    Hi Debashis,

    The kernel source code has the required header files. When you have the kernel source code, you don't need a separate kernel headers to compile any off-tree kernel modules, rather you just need to pass the kernel source code directory to the off-tree kernel module when compiling it.

    Using the cryptodev module in the Processor SDK Linux package as an example. Following is the cryptodev module Makefile taken from <SDK10.0>/board-support/extra-drivers/cryptodev-module-1.13+git/.

    3482.Makefile

    You can see line 30 is the following, which is to compile the cryptodev module.

            $(MAKE) $(KERNEL_MAKE_OPTS) modules

    $(KERNEL_MAKE_OPTS) is defined in line 6, which is

            KERNEL_MAKE_OPTS := -C $(KERNEL_DIR) M=$(CURDIR)

    The option "-C" indicates the variable $(KERNEL_DIR) pointing to the kernel source code.

    Now let's see how the SDK compile the cryptodev module. Following is the SDK makefile to cryptodev, it is taken from <SDK10.0>/makerules/.

    Makefile_cryptodev

    You can see line 5 is the following, which defines KERNEL_DIR to $(LINUXKERNEL_INSTALL_DIR) which is defined in the SDK global configuration pointing to the kernel source code.

            $(MAKE) -C $(CRYPTODEV_SRC_DIR) ARCH=$(ARCH) KERNEL_DIR=$(LINUXKERNEL_INSTALL_DIR)

    Hi Bin,
    Let me tell you the full steps what we followed to build , dump kernel and install ethercat.
    we are building ethercat on running linux host system not in local system with cross compilation tools

    download the ti-processor-sdk-linux-rt-am62pxx-evm-10.00.07.04-Linux-x86-Install.bin form webpage

    commands to build kernel what we followed is:

    make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" modules
    sudo cp arch/arm64/boot/Image /media/rootfs/boot
    sudo make ARCH=arm64 INSTALL_MOD_PATH=/media/rootfs modules_install
    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX


    After copying the image and modules we required linux-header for the updated kernel. so for that I compared the files with an existing Linux header folder and copied the same structure from the Linux RT SDK to the SD card.

    for that I use this headers_install command and copy the rest file which is required in linux header

    Then I boot the sdcard and try to install ethercat in Linux host

    Is this the correct steps what I followed?
    Please let me know if my understanding is Wroge somewhere?

    Hi Debashis,

    I never did compiling a kernel module on a running ARM Linux, but always used cross-compile. But I found the following kernel documentation, which tells the kernel headers are for Linux user space program, not off-tree kernel modules.

    https://www.kernel.org/doc/Documentation/kbuild/headers_install.txt

    Ethercat is out of my support scope, so I don't know why it doesn't support cross-compile (or it does, you just didn't use it).

    Bin:  igh is an implementation of an EtherCAT master (see  docs.etherlab.org/.../index.html   ) The fp@igh.de in line 16 leads to that vendor. (aka  Florian Pose, Ingenieurgemeinschaft IgH)  Maybe you should forward info to  +) Thomas Leyrer's Profile - Thomas Leyrer - TI E2E support forums   in the Industrial Automation Lab in Germany as he might be able to assist?
