I replicated the steps you provided based on the instructions you gave and found that you missed one step, which is the "clean" operation in Buildroot. After deleting the <luckfox-pico path>/sysdrv/source/buildroot/buildroot-2023.02.6/output, you simply need to return to the root directory of the SDK and execute
Code: Select all
make
cd ../../../../ #to Sdk path
./build.sh clean rootfs
./build.sh rootfs
./build.sh firmware
Thank you very much for your exploration and feedback on Luckfox-pico. We will continue to strive to make its SDK even more perfect.
