AM6442: Create yocto rootfs

pingan fan

Part Number: AM6442
Other Parts Discussed in Thread: SK-AM64B

Tool/software:

hi sir :

I have installed ti-processor-sdk-linux-am64xx-evm-10_01_10_04-Linux-x86-Install.bin and successfully run make all. I used the script bin/create-sdcard.sh to create an SD card image and wrote it using the SDK's default build files. Now, I want to use custom boot/rootfs tar packages or directories, but the SDK does not seem to include the Yocto-based rootfs source code.

After running make all, I did not find any rootfs build process or generated images. How can I resolve this?

If you starting a new project, you should use our most current SDK, which right now is v11.0, to benefit from latest Linux Kernel, U-Boot, drivers, firmwares, demos, and so on. See https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-RT-AM64X

The Yocto environment is not part of the SDK installer, but is getting setup directly from source trees pulled in from the Internet via `git clone`. The documentation has all the details here: https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/11_00_09_04/exports/docs/linux/Overview_Building_the_SDK.html

I am using "Create SD Card with custom images" and selected "Enter in custom boot and rootfs file paths". I entered the Boot Partition path, but I don’t know how to choose the ROOT path. I selected the option: "Provide a directory that contains the kernel image and device tree files to be used" because I want to use my own kernel image and device tree files. However, how should this path be configured? Do I need to place all the compiled device tree images and kernel images from the SDK into a single folder? Additionally, after completing this option, it asks me to select the rootfs path again. Can I use the default rootfs file from the system’s built-in filesystem?

Additionally, after completing this option, it asks me to select the rootfs path again.

I'm not too familiar with the exact operation of the script when applying such customizations but you can just look at its source code and you'll see exactly where it will be trying to pull files from for Kernel, DTB, and rootfs in accordance with the options that are selected.

Another (more straightforward way I think) would be to just program an initial SD card image with everything the SDK provides; and then mount this image (via SD card reader) and replace the files you want to replace. Note that if you replace the kernel you typically also want to update the kernel modules in sync with it to maintain compatibility (otherwise none of the kernel modules will get loaded).

I still think the best is to use Yocto to just generate a new ready-to-flash WIC image directly. This also has the advantage that all your changes are immediately ready to re-build and re-deploy any time in a repeatable and organized fashion (rather than relying on some scripting and manual command selections etc.)

Yes that shouldn't be an issue.

Thank you for your response. The issue with writing to the SD card using the script has been resolved. However, after flashing my self-compiled device tree (DTB) and kernel files, I encountered the following error.

This is running on an off-the-shelf SK-AM64B board, right?

Where does the kernel come from?

Our current SDK (v11.x) production kernel can be found here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/log/?h=ti-linux-6.12.y

For our previous SDK (v10.x), the production kernel trees are https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/log/?h=ti-linux-6.6.y as well as https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/log/?h=ti-rt-linux-6.6.y (for Linux-RT).

Please use one of the TI kernel trees (and associated defconfig & prune steps, see SDK documentation) to confirm correct operation and as a starting point for anything custom.

Regards, Andreas
