AM62A7: SOC system startup time is more than 20s.

meng Ke

Part Number: AM62A7

Tool/software:

Here is the startup time in the evm board.
1. u-boot 5s (Using Serial NAND Boot Mode) with SOC type hs-fs
2. Linux Kernel 13s

3. usr space : 5s

4. application : 3s

Total : 26s

Can you share me how to reduce the system start up time.

the customer accept the system should display the video from power on within 3s.

I have try to reduce the startup time by this action":
1. Flash the software into Nand Flash(include tispl.bin. u-boot.img uboot3.bin) and remove the autobootdelay time to 0. Did there have any other action can be implement in u-boot to reduce the boot time
2. linux kernel: did there have any example that i can do with the kernel. right now. I check with the .config file and remove same setting. but not very much time save be this acition. Did you have any example for the config file. or whitch dts can be remove in the kernel.

3. use space . i have no idea how to do to reduce the time for use space.

Hi Meng,

You can achieve fast boot when you use SBL boot flow.

Please follow the instructions provided in the below link to achieve fast boot.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_01_00/exports/docs/linux/How_to_Guides/Target/How_to_boot_quickly.html

Also, you can use the below thread as a reference in order to achieve Falcon mode enabled in SPL (Program loader) boot flow. This is for AM62x SoC but you should be able to do similar changes for AM62A.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1506904/am625sip-falcon-boot-on-sdk-10

Hope this helps.

Best Regards,

Suren

Hello Suren Porwar:

I am using the SDK with the name "ti-processor-sdk-linux-edgeai-am62a-evm-10_00_00_08-Linux-x86-Install.bin",

The SDK in my PC do not used "k3-am62x-sk-common.dtsi" & tispl.its and other file you mention in the link.

And I check with the guide. Falcon mode will used the MCU app. but this SDK do not have MCU used.

File in 6.1.11.2.1. Secondary Boot Loader (SBL) mention all not exit in this SDK.

Can you help to check. thanks very much

Hi Meng,

If you don't use MCU or SBL, please only refer to the second link Suren provided.

k3-am62x-sk-common.dtsi is for device AM62x, which is what used in the referred link. Since you use AM62Ax device, please do the similar modification to file k3-am62a7-sk.dts.

It seems there are a lot of modifications from 9.x to 10.x. Can you help provide a latest patch and steps that enable falcon model on am62a sdk 10.01?

Hi Bin,

Also, I cannot find "bootargs" in ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/board-support/ti-linux-kernel-6.6.58+git-ti/arch/arm64/boot/dts/ti/k3-am62x-sk-common.dtsi right now.

Hi Adam,

You need to copy the contents of scripts/tispl-linux-falcon.sh in u-boot. Although the patch is reversed, but you need to create this file on your setup and try it out.

Best Regards,

Suren

However, the boot time is still 10s counting from the first line in log. I am using tiny filesystem and I am using sdk 10.1 and sd boot mode.
I will try emmc boot mode later.

Hi Suren,

Now I am using EMMC booting now, but the booting speed is still slow:

Hi Adam,

Mainly two more things to do to further optimize the boot time.

1. disable kernel log to the console.

[2025-05-19 19:47:00] [ 0.000000] Kernel command line: console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 root=/dev/mmt

Please remove earlycon= from the kernel command line, and add "loglevel=0" to it.

2. optimize systemd in rootfs.

The log shows rootfs systemd takes about 4 seconds in boot. This rootfs could be optimized to reduce boot time. Customer should analyze what in systemd are not needed and remove them from rootfs.

Hi Bin,

After removing log and using falcon boot, booting time is now 7 seconds:

But when I want to optimize booting script with this guide:

https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_01_00/exports/docs/linux/How_to_Guides/Target/How_to_boot_quickly.html#reducing-userspace-boot-time

There is no such file.

How to remove startup scripts in tiny fs? And please file a jira to fix this documentation error.

Also, you can see authentication takes up almost 1.5 seconds. What can I do with this part?

here is my steps

1. in SDK

cd filesystem/
mkdir output
cd output/
tar -xf ../tisdk-tiny-image-am62axx-evm.rootfs.tar.xz
ln -s sbin/init init
cd dev
sudo mknod -m 0666 null c 1 3

2. add the following to arch/arm64/configs/defconfig in linux

CONFIG_INITRAMFS_SOURCE="/home/ht/ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05/filesystem/output"

3. in SDK top folder

make linux

sudo cp board-support/ti-linux-kernel-6.6.58+git-ti/arch/arm64/boot/Image /media/ht/root/boot/Image-initramfs
cd /media/ht/root/boot/
sudo ln -sf Image-initramfs Image
sync

then boot from sd card.

Adam,

Adam Hua said:
There is no such file.

How to remove startup scripts in tiny fs?

Those rc*.d/* files should be in the tiny rootfs in the SDK.

Adam Hua said:
Also, you can see authentication takes up almost 1.5 seconds. What can I do with this part?

I believe Suren has supported several customers for falcon boot on HS-FS devices, but he is traveling this week, we will have his comments on this once he is back.

Adam Hua said:
I also tried systemctl stop to disable all services. But there are still logs of the disabled services.

The log shows many services are not disabled.

Adam Hua said:
Then I tried initramfs and booting time is not reduced.

Did you optimize the systemd service in the tiny rootfs?

You can continue work on disabling those unnecessary services, or move to SYSVInit boot script if the customer project can use it.

The tiny rootfs provided in SDK8.6 uses SYSVInit instead of systemd.

Hi Bin

We have limited knowledge of the systemd services and we need your help in how to disable some services and what services can be disabled. Time is urgent.

Bin Liu said:
I believe Suren has supported several customers for falcon boot on HS-FS devices, but he is traveling this week, we will have his comments on this once he is back.

Also I find the time consumption here is not for authentication but comes from loading the images. The time will be less if we use smaller linux image.

We need your help in further optimize linux image size and disabling unnecessary systemd services.

Regards,

Adam

Adam,

For optimizing kernel Image size, you would have to check the kernel .config file to see what options are enabled but not needed, then disable them.

I don't have an instruction for optimizing systemd services, you would have to study how systemd works and disable unused services. I only used SYSVInit a couple years ago when I worked on Linux fast boot, but I didn't use systemd in rootfs.

You might also want to the apply the U-Boot patch attached below to skip memcpy() in image loading process. It should save some time too.

Hi Bin,

Since I am using falcon boot mode, uboot is skipped.

During boot, I notices loading image gets too slow for kernel image in tispl with image size 15MB.

With enabling more log, I found mmc is configured at HS mode, which is too slow

Then to add UHS or HS200 support, I add two lines in configs/am62ax_evm_r5_defconfig

CONFIG_MMC_IO_VOLTAGE=y

CONFIG_MMC_UHS_SUPPORT=y

but boot fail with:

Is there any example of setting mmc at HS200 in tiboot3 booting period?

(Repeat step 1 since linux image is modified)

3. disable initial init script and systemd

create an init script called myinit.sh

#!/bin/sh

export PATH=/usr/bin:/sbin:/bin
export LD_LIBRARY_PATH=/lib:/usr/lib:$LD_LIBRARY_PATH
mount -t proc proc /proc
mount -n -t sysfs none /sys
mount -n -t tmpfs none /run

echo "Hello world!!!!!!"

/bin/sh

copy this to boot media

cd (your rootfs part)/sbin

mv init init_back

ln -s myinit.sh init

This script is too simple to run complex applications but you can modify it according to the file attached in this FAQ:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1110814/faq-tda4vm-how-to-optimize-surround-view-use-case-to-2-3-seconds-from-power-on

Adam,

Great progress.

Bin Liu said:
You might also want to the apply the U-Boot patch attached below to skip memcpy() in image loading process. It should save some time too.

6557.0001-spl_fit-skip-memcpy-to-save-loading-time.patch

Have you applied this patch? I don't remember the exact number, but I believe it should save at least a few hundred msec in kernel image loading time.

Hi:
I have disable the init script and systemd and using myinit.sh to implement the fast start of kernel. here is setting in myinit.sh. and for the setting below. v4l2 and gsteamer can be insert into project.

But the camera can not be add into device:
sh-5.2# ls /dev/video*
/dev/video0 /dev/video2 /dev/video4 /dev/video6 /dev/video8
/dev/video1 /dev/video3 /dev/video5 /dev/video7
sh-5.2#

Can you help to check if the setting is incorrect. and how i should to correct it. thanks very much

Hi Meng,

Since you created another thread to track the v4l2 and camera, do you still need support here? I am going to close this one and continue to discuss on the below thread:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1519349/am62a7-q1-linux-kernel-service-and-driver-failure-v4l2

Best Regards,

Suren
