S32G3 IPC Demo Question

[Coco111]

the demo seems doesn't work.

Step1: Compile IPCF_Example_S32G399_M7_0_demo.bin

Note:modification

       Local shared mem addr:    0x34200000 

       Remote shared mem addr:0x34100000

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

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

The system is stuck, possibly because no interrupt was received.

Hi Ni Yu

Hope You are doing well

You are using bsp35.0, right. i think you not need to compile ipc-shm-dev.ko and  ipc-shm-sample.ko.

both module may already compiled. can you check in your board

as  root@s32g274ardb2:~# ls /lib/modules/`uname -r`/extra/ipc-shm-dev.ko
      root@s32g274ardb2:~# ls /lib/modules/`uname -r`/extra/ipc-shm-sample.ko

check and let us know

Regards ,

Tushar
