AM6442: AM642 Falcon Boot – Root filesystem not mounting when initramfs is embedded in kernel (Processor SDK 11.01.05.03)

Part Number: AM6442

Dear TI Team,

I am working on Falcon boot on the AM642 EVM using Processor SDK Linux 11.01.05.03.

I followed the Falcon boot documentation and was able to successfully boot the kernel directly from U-Boot Falcon mode. The kernel boots correctly.

However, after the kernel boots, the root filesystem on the SD card (/dev/mmcblk1p2) is not mounted automatically. 
so whatever i write gets erased post boot.
How can i automate to mount it.

Best regards,
Sonu

  • Hi Sonu,

    Can you please attach the full console boot log?

  • I followed the Falcon boot documentation

    Please also point me to the documentation you followed.

  • Hi Bin,

    I followed link:

    [FAQ] AM625: How to boot from R5 U-Boot SPL directly into the Linux Kernel, skipping A53 SPL and A53 U-Boot (Falcon Mode) - Processors forum - Processors - TI E2E support forums 

    I was able to achieve automatic mounting using the following method:

    1. Extracted the etc/fstab file from the tisk-tiny-initramfs.cpio.

    2. Added the following entry to mount the SD card partition:

      /dev/mmcblk1p2 /root ext4 defaults 0 0
    3. Repacked the modified files into a new cpio archive.

    4. Combined this archive with the original initramfs cpio and compressed it.

    With this approach, the SD card root filesystem is mounted automatically.

    Before adding the automount configuration, the boot time was approximately 8.3–8.5 seconds (including systemd).
    After adding the mount command, the boot time increased to approximately 9.59 seconds.

    Could you please suggest if there is a better or more optimal method to achieve this?

    My end goal is to achieve fast boot while running remoteproc and an application on Linux.

    To run my application on Linux, I added a service under /etc/systemd/system using the same method (modifying the initramfs), and it is working correctly.

    Currently, I am trying out same method for remoteproc.

    The main challenge with this approach is that every time the application binary (.out file) changes, I need to rebuild the initramfs and the kernel.

    I would appreciate any suggestions or best practices for handling this more efficiently.

    Below is the boot log for reference.

  • Hi Sonu,

    Thanks for the explanation. I understand the problem now.

    I don't have benchmark numbers for the boot time between initramfs and external rootfs, mainly because the numbers would highly depend on the configuration/init-scripts of the rootfs.

    However, you don't need to use both (using initramfs initially then switching to rootfs on a storage - sdcard in your case). Depending on your use case, you only need to use one of them, meaning either using initramfs or not using it.

    The main challenge with this approach is that every time the application binary (.out file) changes, I need to rebuild the initramfs and the kernel.

    I would appreciate any suggestions or best practices for handling this more efficiently.

    I would recommend you separate the two tasks - boot time optimization and remoteproc application development. You can use normal boot flow for your remoteproc application development so that you don't need to rebuild the initramfs/kernel everytime the .out file is changed. Even better, you might want to use NFS rootfs for your remoteproc application development, which is even faster in .out file deployment.
