Dear all,
I want to test USB OTG as storage device but I have some problem with adding kernel modules.
I currently use yocto with 3.14.52 version. Actually, I add g_mass_storage support as module but, it doesn't exist on kernel. Here is my log file.
root@imx6dlsabresd:~# insmod g_mass_storage.ko file=/dev/mmcblk1p1
insmod: can't insert 'g_mass_storage.ko': No such file or directory
root@imx6dlsabresd:~# uname -a
Linux imx6dlsabresd 3.14.52-1.1.1_ga+gdb1bcba #140 SMP PREEMPT Thu Jul 21 16:50:46 EEST 2016 armv7l GNU/Linux
root@imx6dlsabresd:~#

&usbotg {
vbus-supply = <®_usb_otg_vbus>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usbotg>;
disable-over-current;
srp-disable;
hnp-disable;
adp-disable;
status = "okay";
dr_mode = "otg";
};
pin config:
Here are my kernel config about selection.

I think you must run "bitbake core-image-minimal", so you miss "kernel" directory.
At least you should run "bitbake core-image-base".

Hi,
I understand that yocto generates modules.tar.gz separetly. I just refresh zImage and rootfs. Now the problem solved.
Thanks
That means no module installed default, so you should install modules manually.
modules in directory /lib/modules/3.14.28-1.0.0_ga+g91cf351/kernel
you can find "g_mass_storage.ko" in "/lib/modules/3.14.28-1.0.0_ga+g91cf351/kernel/drivers/usb/gadget"
root@imx6dlsabresd:/lib/modules/3.14.52-1.1.1_ga+gdb1bcba# ls
extra modules.builtin.bin modules.order
modules.alias modules.dep modules.softdep
modules.alias.bin modules.dep.bin modules.symbols
modules.builtin modules.devname modules.symbols.bin
There is no related kernel directory on my side. Kernel directory and kernel objects are missing. I don't know I have chosen all gadget as a module. I follow the referance manuel but, it seems that something is missing. What could be the reason that why kernel directory is missing on my system.
HI Eren
for usb tests one can look at imx-test package (folder ../test/mxc_usb_test)
http://patches.openembedded.org/patch/110753/
also please check attached Linux Manual Chapter 40
CHIPIDEA USB Driver
Best regards
igor

Hi,
I followwed the docuement and now. The module exits but there is something strange. The module exist but, it can unloadable with modprobe.
root@imx6dlsabresd:~# find / -name g_mass_storage
/sys/module/g_mass_storage
root@imx6dlsabresd:~# modprobe g_mass_storage
modprobe: module g_mass_storage not found in modules.dep
root@imx6dlsabresd:~#
Best Regards,
Eren
As storage device, you can run commands as below,
insmod configfs.ko
insmod libcomposite.ko
insmod usb_f_mass_storage.ko
insmod gadgetfs.ko
insmod g_mass_storage.ko file=/dev/mmcblk1p1
run "lsmod" to list modules installed.
Actually, no kernel object shown. I selected the parameters which are written in I.MX6 Linux Referance Manuel-40.
root@imx6dlsabresd:~# lsmod
Tainted: G
galcore 225842 0 - Live 0x7f000000 (O)
