S32G3 IPC-shm-us Question

Coco111 — Mon, 10 Jul 2023 09:29:55 GMT

Can you provide a script of how to compile ipc-shm-us for S32G399?

The current work is as follows:

一. Build kernel

git clone https://github.com/nxp-auto-linux/linux

git checkout bsp35.0-5.10.145-rt

export ARCH=arm64

export CROSS_COMPILE=/home/niyu/Desktop/S32G/BSP/seperate/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
make s32cc_defconfig

make

二. compile ipc-shm-us

git clone https://github.com/nxp-auto-linux/ipc-shm-us.git

git -C ipc-shm-us submodule update --init --remote
git -C ipc-shm-us checkout release/bsp35.0
git -C ipc-shm-us/common checkout release/bsp35.0

the first compilation is ok

export ARCH=arm64
export CROSS_COMPILE=/home/niyu/Desktop/S32G/BSP/seperate/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
export PLATFORM_FLAVOR=s32g3
make -C ./ipc-shm/sample PLATFORM_FLAVOR=s32g3 KERNELDIR=$PWD/linux modules

but the following command failed

make -C ./ipc-shm-us/sample IPC_UIO_MODULE_DIR="/lib/modules/5.10.145-rt74+g09ebf03aa02c/extra"

Hi Ni Yu

Hope you are doing well

Thanks for reaching to us. There may be sample.c compiles as user environment and uses ipc-shm.o which compiled for module. can you try below things

make -C ./ipc-shm-us/ clean

make -C ./ipc-shm-us/sample IPC_UIO_MODULE_DIR="/lib/modules/5.10.145-rt74+g09ebf03aa02c/extra"

and let us know if not solved

Regards ,

It takes effect, thank you very much. It's a problem with the ipc-shm. o file

But the demo seems doesn't work.

Step1: Compile IPCF_Example_S32G399_M7_0_demo.bin

Step2: Compile ipc-shm-dev.ko &&ipc-shm-sample.ko

git clone https://github.com/nxp-auto-linux/ipc-shm.git

git checkout SW32G_IPCF_4.8.0_D2212

export ARCH=arm64

export CROSS_COMPILE=<DIR>/Desktop/S32G/BSP/seperate/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-

make -C ./ipc-shm/sample PLATFORM_FLAVOR=s32g3 KERNELDIR=$PWD/linux modules

Note: Modification of ipc-shm (Is this a source code error?)

step3 run demo

uboot=>dcache off;

uboot=>mw.q 0x34000000 0x0 0x100000;

uboot=>tftp 0x80000000 IPCF_Example_S32G399_M7_0_demo.bin;

uboot=>cp.b 0x80000000 0x34300000 0xc0000;

uboot=>startm7 0x34381000

linux#insmod ipc-shm-dev.ko;insmod ipc-shm-sample.ko;

linux#echo 10 > /sys/kernel/ipc-shm-sample/ping

I got an error:

I realized that the PFE driver may interfere with the IPCF, so I adjusted the IPCF to use 0x34100000 (1M) 0x34200000 (1M) as the data interaction space. However, the system is in a stuck state, possibly due to the inability to obtain interrupts

ipc-shm demo

ipc-shm-us demo

I have currently checked the IPCF version, shared SRAM address, and possible conflicts.

But there are still issues, please help me. How should the s32g399 platform use this demo
