I want to simulate an USB thumb drive using the Yosemite's device interface. So the Yosemite board is the thumb drive. I am not trying to connect a thumb drive to the Yosemite. Sorry if I wasn't clear. I do not believe the device-side driver for the 440EP Musbhsfc is in the kernel tree yet, so this will give me a chance to test the patch that Wade Farnsworth released last September. >> if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map >> -b /opt/eldk4/ppc_4xxFP -r 2.6.15-g6afd198e; fi >> make: *** [_modinst_post] Error 139 >> >> I see a g_file_storage.ko but I get an "Invalid module" if I >> try to modprobe it. > > Your native system's (x86 ?) module utilities (depmod, modprobe) do > not understand PowerPC modules.

Thanks, I'll work on that. >> I do want to solve this problem, but if anyone wants to give >> me the trick to building the gadget driver into kernel and >> passing the file=disk_image parameter, I'd like to know that >> as well. > > What exactly do you have in mind? Menuconfig does not let me build-in the gadget filesystem driver. It insists on it being a module. I saw something that says you can build one gadget driver into the kernel, but I was not able to figure out the trick. I'm also not clear about passing parameters to the driver, but I'll try bootargs first.
