how to install user build linux kernel modules on SD-Card

Sujata Ingale

Hi All,

I am working on TI-Linux SDK for AM335x Starter kit.

have done some changes in usb/gadget.zero.c file.

i have created .ko and .o files for that.

When i tried to load this modules on SD card with "Modules_install command", i can see that the modules that are installed in rootfs/lib/modules/kernel/drivers/usb/gadget folder are the one which come with standard SDK pack.

when i run modinfo on the prepared SDcard (by entering in /media/rootfs/......) for g_zero.ko file i see the details as those are built for ARMv6,

but if i see the modinfo on the SDK of ti (home/igate/ti-sdk-directory/usb/gadget/) for the same file g_zero.ko isee the details a those are build for ARMv7.

What should be the steps to follow to install the modified modules on SD card?

Thanks in advance.....

Hi Miroslav,

Thanks for your reply.

I am able to build the SD-card and install modules on that. but the problem occurs when i try to install the modules when i have done some changes in usb_gadget side functionality.

After building my modules when i install them on SD-card, i see the modules those are coming with SDK are installed and not the one which i had built.

Basically i was having problem in Modinfo command. the newly built modules are against ARMv7 where standard SDK modules are with ARMv6.

Thanks in advance..
