It was meant as an example, when I compiled my minimal file system it didn't supply the firmware.sh script nor created /lib/firmware... I thought that not everybody would have the firmware.sh, so I just provided a sample rule. > Why doesn't the default firmware loading rule that comes with udev work properly for you? > What are you needing different here that works properly for all other drivers? firmware.sh under /lib/udev/ and dsp binaries installed under /lib/firmware/, my rule is the brute version of firmware.sh so nothing different in the script. Probably the only change would be to supply the firmware name only, as of now the insmod parameter requires the entire path, e.g.: insmod bridgedriver.ko base_img=/lib/dsp/baseimage.dof if using firmware.sh and placing firmware files under /lib/firmware/, then insmod bridgedriver.ko base_img=baseimage.dof Should be enough.
