hi，nxp：

       After the u-boot module starts the M7 core IPCF sample code through the following instructions, why does the A core insmod keep reporting a segmentation error when installing the sample project code。

      1.dcache off
      2.mw.q 0x34100000 0x0 0x40000
      3.fatload mmc 0:2 0x80000000 M7.bin
      4.cp.b 0x80000000 0x34300000 0x300000
      5.startm7 0x34500400

hi，liujian_abup

Thank you for contacting us.

Which version of BSP/IPCF are you using?  Does the M.7 is load normally?

When you compile IPCF, which version of kernel are you using? You should use the Image in the Kernel replace the defeat Image in BSP, have you tried to do so?

Hope it can help you.

hi， Joey_z
 bsp version ： 43
 IPCF Version ：SW32G_IPCF_4.10.0_D2405（A53和M7版本一致）

 M.7 loads normally
 I'll try the replacement operation

hi,liujian_abu

Have you modified the source code of IPCF and the driver code of IPCF for A core? Your loading address is different from that of the RTD demo.

No modification

hi,liujian_abup

If you use the IPCF_Example_multi_instance_S32G399A_M7_0 demo in RTD,  you can do it to refer to the step as shown the following picture.

1.U-boot load the M core .bin file.

Refer to the content in picture to load.

2. insmod the .ko file.

It only has the M7_0 .bin, please ensure the load address correct.

Hope it can help you.

hi, Joey_z

It still crashes when using the insmod IPCF sample

The MCU has recreated it based on the screenshot you provided, and the load address is consistent with yours. The 7z file in the attachment is the sample I used for debugging here.

thank you.

hi，

Thank you for your reply.

I can not use your ipc-shm-sample_multi_instance.ko  file as the shown following picture.

Please check the uboot/kernel version on IPCF.

This is the way to compile the IPCF for .ko.

make -C ***/ipc-shm/sample_multi_instance PLATFORM_FLAVOR=s32g3  KERNELDIR=***/linux ARCH=arm64 CROSS_COMPILE=**/aarch64-none-linux-gnu- modules   4.10.0
