- a1
${MC} : machine code combined with ${IMX8PROC}${BOARD}${BOARD_REV}
- for example,
-
- imx95aom3511a1 for AOM-3511 A1
- You can also use the command below to check supported machines on BSP
$ source setup-environment
${MEM_SIZE} : memory size
- 1G/2G/4G/6G/8G
${UC} : u-boot config
- 1G/2G/4G/6G/8G/FSPI_1G/FSPI_2G/FSPI_4G/FSPI_6G/FSPI_8G...

${SDCARD_IMAGE} : sdcard image built by bitbake (*.wic.zst)
${WORKSPACE} : host workspace folders
${UBOOT} :u-boot version(e.g. v2023.04_6.6.3-1.0.0)
${KERNEL} : linux kernel version(e.g. 6.6.3-1.0.0)
${TOOLCHAIN} : toolchain installed directory(e.g. /opt/fsl-imx-xwayland/6.6-nanbield/environment)
debug console / serial console
- serial terminal program (e.g. minicom, putty, teraterm ...) that serial port is configured to 115200 8N1
terminal console
- terminal program (e.g. gnome-terminal, xfce4-terminal ...)
Docker install and setting
If you don't have docker in your system, then you can follow the below steps to install docker and run it first.
To install Docker Engine on your platform
- Please refer to Docker Installation Guide for details
To pull ubuntu 20.04 image from Docker Hub
$ docker pull advrisc/u20.04-imx8lbv1
To create container
$ docker run --privileged -it --name ${CONTAINER_NAME} -v ${WORKSPACE}:/home/adv/adv-release-bsp -v /dev:/dev advrisc/u20.04-imx8lbv1 /bin/bash
Get BSP
- You have two methods to put BSP into container created above
Download_BSP_From_GitHub
- The following example shows how to download the Advantech Yocto BSP from GitHub.
- For this example, a directory called adv-release-bsp is created for the project.
- Refer to IoTGateway/BSP/Linux/iMX9/OS_Support_List , Official version "imx9LBVEXXX" is taken as an example :
$ git config --global user.name "Your Name" $ git config --global user.email you@example.com $ sudo chown adv:adv adv-release-bsp $ cd adv-release-bsp $ repo init -u https://github.com/ADVANTECH-Corp/adv-arm-yocto-bsp.git -b imx-linux-nanbield -m adv-6.6.3-1.0.0.xml $ repo sync
- f you suffer "server certificate verification failed", you can use the following command to disable SSL verification in git repositories with self-signed certificates.
$ export GIT_SSL_NO_VERIFY=1
or
$ git config --global http.sslverify false
- If you get "The unauthenticated git protocol on port 9418 is no longer supported.", you can try it.
$ git config --global url."https://".insteadOf git://
Copy BSP tarball to Container
- If you have BSP tarball (eg. imx9LBVE0017_2024-08-21.tgz), then you have to copy it into container.
Follow the steps below:
1.Exit container and back to local machine
$ exit
2.Copy BSP tarball to ${WORKSPACE} , and change owner
$ cp imx9LBVE0017_2024-08-21.tgz ${WORKSPACE} $ sudo chown adv:adv ${WORKSPACE}/imx9LBVE0017_2024-08-21.tgz
3.Back to container
$ docker start ${CONTAINER_NAME} $ docker attach ${CONTAINER_NAME}
4.Unpack BSP tarball
$ tar zxvf imx9LBVE0017_2024-08-21.tgz
Downloads tarball
- Not necessarily step
- During building Yocto image , it will generate downloads folder which includes all packages we need , but it usually can't fetch normally, so we keep this downloads folder. Then we can reduce some fetch failed issue.
- You can get Downloads tarball (downloads_6.6.3_1.1.0.tar) from following URL:
- If you get downloads tarball, you can copy to your ${WORKSPACE}
Follow the steps below:
1.Exit container and back to local machine
$ exit
2.Copy Downloads tarball to ${WORKSPACE} , and change owner
$ cp downloads_6.6.3_1.1.0.tar ${WORKSPACE} $ sudo chown adv:adv ${WORKSPACE}/downloads_6.6.3_1.1.0.tar
3.Back to container
$ docker start ${CONTAINER_NAME} $ docker attach ${CONTAINER_NAME}
4.Unpack Downloads tarball
$ tar zxvf downloads_6.6.3_1.1.0.tar
5.make link to downloads folder
$ cd adv-release-bsp $ ln -s ${WORKSPACE}/downloads_6.6.3_1.1.0 downloads
Introducing BSP
- The BSP is based on Yocto Project with Freescale enhanced features for i.MX95, plus specific target board features from Advantech Inc..
The Advantech Yocto Project BSP Release directory contains a "sources" directory, which contains the recipes used to build,
one or more build directories, and a set of scripts used to set up the environment.
- The recipes used to build the project come from both the community and Advantech. The Yocto Project layers are downloaded
to the sources directory. This sets up the recipes that are used to build the project.
Naming Rule
- The tarball/prebuilt image name is consist of the model name followed by "LB" or "LI" plus version number and released date.
- For example, BSP file name: imx9LBVE0017_2024-08-21.tgz
which , "LB" is acronym of Linux BSP,
"VE0017" stands for Version E.0017
- For example, Yocto image name: '3511A1AIM37LIVE0017_iMX95_8G_2024-08-21.img.gz'
which "3511A1" stands for AOM-3511 A1
"LI" is acronym for prebuilt Linux Image
"8G" is DDR size

Creating boot-up on-board flash from prebuilt image
To create one boot-up SD card
- Perform the following command in terminal console
# gunzip -c ${PREBUILT_IMAGE} | dd of=${SD_DEVICE} bs=1M

Creating boot-up on-board flash from built sdcard image
To create one boot-up SD card
- Perform the following commands in terminal console
$ pushd ${BSP_HOME}/${BDIR}/tmp/deploy/images/${MC}
$ zstd -cd ${SDCARD_IMAGE} | sudo dd of=${SD_DEVICE} bs=1M

$ sudo bmaptool copy --bmap ${SDCARD_IMAGE/zst/bmap} ${SDCARD_IMAGE} ${SD_DEVICE}
$ sync
$ popd
Debug console information
If you want to see debug message from device, you need to prepare for hardware device and software tool.
Preparing for hardware device
- The following URL provides information about the debug port slot and the debug port line for each device
Preparing for software tool
- You need to prepare the debug console tool. For example: "minicom" tool or "putty" tool.
*Baud rate: 115200

Build U-Boot in standalone environment
Config u-boot
make ${IMX8PROC}_${BOARD}${BOARD_REV}_${MEM_SIZE}_defconfig
eg.
make imx95_aom3511a1_8G_defconfig
Build u-boot
make -j4
Build imx-boot image by using imx-mkimage for imx95
Get imx-boot tarball from our server Here we take aom3511 as an example:
$ tar zxvf 3511A1AIM37LIVE0017_iMX95_8G_imx-boot.tgz $ cd 3511A1AIM37LIVE0017_iMX95_8G_imx-boot/
In this folder ,Copy necessary files to imx-mkimage folder
$ cp ${u-boot.bin、spl/u-boot-spl.bin、arch/arm/dts/imx95-aom3511-a1.dtb、tools/mkimage} imx-boot/iMX9/.
Make imx-boot image
$ cd ~/imx-mkimage $ make SOC=iMX95 OEI=YES flash_all
Replace uuu imx-boot
- Perform the following uuu command to transfer to on-board flash
$ cp flash.bin ~/mfgtools/uuu/. $ sudo ./uuu -b emmc flash.bin
Replace imx-boot
- Perform the following command to transfer to on-board flash
$ sudo dd if=flash.bin of=/dev/sdd bs=1K seek=32 conv=fsync
Building & updating kernel/modules/dtb manually
- The cross compiling environment has been set up. (ref. Setting up cross compiling environment)
Copy BSP tarball to Container
- You can get Downloads Linux-imx from following URL:
[adv_6.6.3_1.0.0]
Config kernel
- Configure linux kernel
$ cd linux-imx $ make distclean $ make imx_v8_adv_defconfig $ make menuconfig
- Start building linux kernel
$ make -j4 Image
- When you get error like below
- run command then rebuild
$ unset LDFLAGS
- The kernel image file, Image, is located in the directory "./arch/arm64/boot/".
- Start building kernel modules
$ make -j4 modules
- Copy all modules to a temporary rootfs directory, "~/temp/rootfs"
$ make modules_install INSTALL_MOD_PATH=~/temp/rootfs
- Building device tree blob
$ make -j4 freescale/${IMX8PROC}-${BOARD}-${BOARD_REV}.dtb eg. $ make -j4 freescale/imx95-aom3511-a1.dtb
- The device tree blob, ${IMX8PROC}-${BOARD}-${BOARD_REV}.dtb, is located in the directory "./arch/arm64/boot/dts/freescale/".
Replace kernel & dts
- Replace kernel
copy Image to SDcard or emmc
Replace dtb file
copy dtb file to SDcard or emmc
Improve boot speed
- Bootloader
1.bootdelay time
- We can cancel the bootdelay time by setting bootloader environment value.
setenv bootdelay 0 env save reset
2.Disable console
- Disable debug message output can also improve boot speed
Disable kernel message
setenv mmcargs setenv bootargs ${jh_clk} console=${console} modprobe.blacklist=${modprobe.blacklist} root=${mmcroot} video=HDMI-A-1:${videores} quiet env save reset
Or
- Disable debug port
setenv console env save reset
- Rootfs
- TBD
- Services
1. Using systemctl disable remove ,we can remove unnecessary services.
systemctl disable <services>
eg.
systemctl disable boottimes
