make modules_install fails with [_modinst_post] Error 139

[John Otken]

I'm trying to build the USB gadget file storage module for
a Yosemite board using the latest Denx kernel and ELDK4.

$ make yosemite_defconfig
$ make menuconfig  # turn on CONFIG_USB_FILE_STORAGE <M>
$ make uImage
$ make modules
$ make modules_install INSTALL_MOD_PATH=/opt/eldk4/ppc_4xxFP
   INSTALL drivers/usb/gadget/g_file_storage.ko
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.

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.

Thanks in advance.

This is not necessary. The default config file for the Yosemite board
has USB and mass storage devices support  already  enabled  (compiled
in, i. e. not as modules). Just use the unmodified config file and it
will work.

Note that CONFIG_USB_GADGET is not set, though (not sure what exactly
you want to do).

Your native system's (x86 ?) module utilities (depmod,  modprobe)  do
not understand PowerPC modules. If you want to run "depmod", you must
overwrite  the  Makefile's  default  setting of DEPMOD to use a cross
version of depmod instead.

What exactly do you have in mind?

Our management frequently gets lost in thought.   That's because it's
unfamiliar territory.

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.

Thanks, I'll work on that.

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.

I see.

Try Busybox' depmod.pl script ...

Overdrawn?  But I still have checks left!
