Luckfox Forums

I have a luckfox pico mini b.
I am unable to run rknn example because of permission error in linux. I tried with chmod but it does not work. I used sd card to store the files because the board didn't have any free space. I have also attached a screenshot for reference.
[My main purpose of buying this board was to run as a web server but was facing network driver issues in ubuntu on this board so I am considering using it for a computer vision project instead]

Hello, if you are using the Ubuntu system (based on glibc), it will fail to run due to the lack of corresponding dynamic libraries and drivers, Rockchip officially only provides the uclibc version of the dynamic library version, so to run rknn related programs, please make sure to use the buildroot system

Hello thanks for the reply!
I think there is a confusion I was using buildroot version only.
In message I told that I removed the ubuntu system because it was not functioning correctly.
In the build root I tried to exec rknn example from sd card because I was unable to copy the files to root. The device doesn't have enough space so I decided to exec it directly from sd card but I am not getting permission even after using chmod.

The flash size of luckfox pico mini B is only 128MB (the size of the model itself occupies 7MB), and running rknn programs on SD cards may have file system permission issues, which you can check with the "mount" command. A better way is to use the SD card directly as the system medium, which can circumvent most of the problems
