Introduction

A very fast boot time it's an important feature of Embedded devices. Read the steps listed in this application Note allows to optimize the major boot stages for reducing the boot time.

The Application Note describes some typical optimizations that can be done on DAVE Embedded Systems's products to shorten the boot time.

Boot parameters

It should be taken into account that boot time results strongly depend on the overall system configuration and involves - mainly - the following parameters:

• U-Boot storage device, i.e. from which device the internal bootrom fetches the u-boot code
• Linux binaries storage device: i.e. where the kernel and dtb binaries are loaded from for copying them on DDR memory
• u-boot startup configuration
  • boot parameters
  • loading binaries optimization
• root file system storage device: i.e. where the rfs is stored
• root file system init process optimization: i.e. which daemons are loaded at the beginning

In this AN we will use the eMMC storage device, mounted in the SOM - using an SDIO bus to communicate with the SoC. It is the fastest device for booting from the complete embedded Linux BSP.

U-boot hacking

U-Boot allows the modification of some environment variables to reduce the timer elapsed in the initial stages:

• bootdelay: this var, used for waiting an interaction from the user to the console, can be reduced to 0 seconds (it is still possible to stop U-Boot)
• quiet: this var, added to the kernel command line, avoids displaying the information messages in the serial console. This reduces a lot the kernel boot time
• bootcmd: this string allows to try and select from different boot sources (USB, SD, eMMC, etc.)
  • once the final storage device has been selected, it is possible to force the boot directly from the selected source
  • mmcargs: in our example, we boot from the internal eMMC loading the kernel and device tree from the /boot directory where the binaries are stored in

root file system optimization

A minimal root file system size allows to reduce the loading and starting time for the system services. Yocto provides a standard recipe for this kind of image: core-image-base.

Starting from this image, it is possible to add your application and services for starting - as soon as possible - the final application.

Falcon mode

This mode allows SPL to boot directly the kernel avoiding the use of U-Boot second stage and reducing a lot this step. NXP provides the AN14093 application note which describes the hacking steps for properly modifying the U-Boot sources.

Test configuration

System configuration

• AURA Evaluation Kit
• SOC: NXP i.MX9352 1.7GHz
• Flash storage: 8GB internal eMMC
• U-Boot SPL 2023.04
• Linux desk-mx93 6.1.55
• root file system: core-image-base

U-Boot

• bootdelay

u-boot=> print bootdelay
bootdelay=0
u-boot=>

• bootcmd

u-boot=> pri bootcmd
bootcmd=run emmcargs; run emmc_loadk emmc_loadfdt; run mmcboot
u-boot=>

• emmcargs

u-boot=> print emmcargs
emmcargs=setenv bootargs root=${emmcroot} logo.nologo vt.global_cursor_default=0 quiet
u-boot=> print emmcroot
emmcroot=/dev/mmcblk0p1 rootwait rw
u-boot=> print emmc_loadk
emmc_loadk=ext4load mmc 0:1 ${loadaddr} boot/${image}
u-boot=> print emmc_loadfdt
emmc_loadfdt=ext4load mmc 0:1 ${fdtaddr} boot/${fdtfile}
u-boot=> print mmcboot
mmcboot=booti ${loadaddr} - ${fdtaddr}
u-boot=>

boot time results

To verify the boot time achieved, a serial port terminal with timestamping grabbing capabilities has been used: the grabserial Linux application is perfectly useful for this purposes.

The original boot time, using the standard dave-image-devel target image, is roughly 20 s (expand the section here below to see the bootlog)
