1.3. Other parts

Tools and Profiles Size Purpose Required
config_tool and mmap.ini When insmod mi_sys.ko, the driver calls config_tool to parse mmap.ini to allocate buffers by hardware. It is located in the /config directory by default. When changing the location, it is required to add default_config_path='/new/path' after insmod mi_sys.ko YES
isp_api.xml Used to connect iqtool to generate software interface projects. When changing the path, it is required to call MI_S32 MI_IQSERVER_SetDataPath(char* path); in mi_iqserver.h before iqserver_open to change the path. NO
iqfile0.bin -> imx307_iqfile.bin When Isp is started (application is running), it will go to the /config/iqfile directory to read the iq file named iqfilex.bin (x means isp channel), the basic effect of the image (usually soft link to the actual iq file). If the location of the file is changed, it needs to be executed before the application runs: echo isproot /new/path > /dev/ispmid YES
chagall.bin HW encoder fireware. The default location is /config/fw_path/chagall.bin. When changing the location, it is required to add fw_path=/new/path/chagall.bin after insmod mi_venc.ko YES
