Hello @MohamedAbdelslam ,
Compiling Linux IPCF indeed requires kernel code. Regarding how to compile a specific version of Linux IPCF (taking Linux bsp40 and IPCF4.9.0 as an example) and perform the insertion operation, please refer to the following steps:
Compile Linux kernel
Refer to sections 3.2.3 and 3.2.3.1 - 3.2.3.2 of the bsp40 document for operation.
Clone the Linux repository and Perform compilation:
git clone https://github.com/nxp-auto-linux/linux
cd linux
git checkout bsp40.0-5.15.145-rt
ls
make ARCH=arm64 CROSS_COMPILE=/path/to/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- s32cc_defconfig
make ARCH=arm64 CROSS_COMPILE=/path/to/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
Compile IPCF modules
Set the cross-compilation tool path, clone the IPCF repository and compile the modules.
export CROSS_COMPILE=/path/to/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
git clone https://github.com/nxp-auto-linux/ipc-shm
cd ipc-shm
git checkout release/SW32G_IPCF_4.9.0_D2310
make -C./sample KERNELDIR=~/path/to/linux PLATFORM_FLAVOR=s32g3 modules
Copy the following image files to the FAT32 partition (boot_s32g27) of the SD card:
- Copy the kernel image (linux/arch/arm64/boot/Image) and replace the original one on the SD card.
- Copy the device tree image (linux/arch/arm64/boot/dts/freescale/s32g274a-rdb2.dtb) and replace the original one on the SD card.
- Copy the IPC images (ipc-shm/ipc-shm-dev.ko, ipc-shm/sample/ipc-shm-sample.ko).
Power on
If everything is okay, you will get the A53 booting log on the terminal. After Kernel is up, enter root to login.
Copy the IPC module files and insert IPCF modules
$mkdir ipc
$mount /dev/mmcblk0p1./ipc
$cp./ipc/ipc-shm-* ~
$umount./ipc
$insmod ipc-shm-dev.ko
$insmod ipc-shm-sample.ko
Hope the above information is helpful to you.
Best Regards,
Celeste
