How can I use the S32V234 Vision SDK1.1.1 together with the S32v234 GPU driver module galcore.ko?

zhangweikanghus · ‎08-21-2018

Hi,expert

I have a s32v234evb28899 borad in my commpany, and I found that I could use Linux BSP17.0 with the VSDK1.1.1。I used the uboot and linux Image created by the Linux BSP17.0(add patch from VSDK1.1.1) as uboot and lmage. And I used the dtb and rootfs.tar.gz from VSDK1.1.1 's build_content 'v234_linux_build'. It worked well and I could use the demo elf from the vsdk.

Unfortunately, I followed the user manual of Auto BSP17.0 to add GPU drivers. It caused that the VSDK drived modules failed to insmod. I just changed the menuconfig and setted CMA size to 32MB as below.

Then the error log was:

Did you rebuild VSDK drivers ? . You need to rebuild VSDK drivers after you build Image and dtb

View solution in original post

nxa13002 · ‎08-30-2018

Hi ,

I have tried with bsp18_rc7 using following steps:

- make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- s32v234_defconfig

- make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig

then follow GPU enable instruction above.

Apply Patch from VSDK

- patch -p1 -i $(SDK_ROOT)/os/linux/0001-s32v234-dts-Add-VSDK-specific-configuration.patch

Then build vsdk drivers and galcore driver. It can insmod all vsdk drivers and galcore driver

zhangweikanghus · ‎08-30-2018

Hi,

Thank you. Can you tell me how can I get bsp18_rc7? I just found bsp17_hf1 in the NXP.com.

nxa13002 · ‎08-31-2018

Hi,

To get bsp_18 rc7 do following steps:

- Go linux repo

- git fetch

- git checkout [tag_bsp18]

But I think that you can insmod galcore with bsp17 with the steps:

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- s32v234_defconfig

- make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig

then follow GPU enable instruction above.

Apply Patch from VSDK

- patch -p1 -i $(SDK_ROOT)/os/linux/0001-s32v234-dts-Add-VSDK-specific-configuration.patch

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

And make sure that you have to build again all vsdk drivers and galcore driver

zhangweikanghus · ‎09-05-2018

Hi,

Thank you. Is Your VSDK version RTM1.2.0 ?

nxa13002 · ‎09-05-2018

Yes, But I am not sure that BSP which is included in VSDK 1.2 that the CMA is enabled or not

zhangweikanghus · ‎09-05-2018

Thank you.

You use galcore.ko built by yourself with the VSDK1.2's Image & dtb & rootfs，and it works successfully?

Does it work successfully with the Image built by BSP18.0?

nxa13002 · ‎09-05-2018

No, I did not use Image and dtb from VSDK1.2 , I built Image and dtb by myself . The Image and dtb from VSDK1.2 did not enable CMA configure .

zhangweikanghus · ‎09-06-2018

Can you show your boot log? I built Image in Yocto and enable CMA configure.Then the kernel module in VSDK‘’s rootfs such as apex.ko cannot insmod.
