[help]: Missing 'sysimage-sdcard.img' After Running 'make CONF=k230_canmv_defconfig’

Help

Hi!

I am attempting to run RVV code on the CanMV-K230-V1.0 board. I have followed the provided build process and executed the command make CONF=k230_canmv_defconfig to build the SDK. However, I am encountering an issue where the sysimage-sdcard.img is not being built in the images directory.

Below is the directory structure of the k230_sdk/output/ after the build attempt:

.
└── k230_canmv_defconfig
    ├── big
    │   ├── mpp
    │   └── rt-smart
    ├── common
    │   ├── big-opensbi
    │   ├── cdk
    │   └── little-opensbi
    ├── images
    │   ├── big-core
    │   └── little-core
    └── little
        ├── buildroot-ext
        ├── linux
        └── uboot

Could you please advise if I have overlooked a step or if there is an additional process needed to generate the sysimage-sdcard.img?

Thanks in advance!

I was able to successfully build the sysimage-sdcard.img. Can you post the output of your build log?

@negge Thank you for checking this!

I reviewed the build log, and I found an issue with the post-imege.sh script:

Have you ever encountered this problem? I will rebuild all things again to see if I can still reproduce the problem.

I've found that when I employ the -j option in the command make CONF=k230_canmv_defconfig (for instance, make CONF=k230_canmv_defconfig -j64), it leads to the issue. If I compile the target using a single job in Makefile (without the -j option), the sysimage-sdcard.img is successfully created.

@negge Thanks again for the reply.

Current SDK does not support multi-process compilation, do not add multi-process compilation options like -j32
