[yocto] Procedure for adding driver in Yocto

[Umamahesh Yelchuruvenkata]

Hi 

I am using wandboard, .bb file in the following path

/yoctoimx-fsl-bsp/sources/meta-freescale-3rdparty/recipes-kernel/kernel-modules

Contains kernel-module-mcc_2.1.01.bb

But how do I edit it to add a new driver. 

Please suggest.

Thanks
Umamahesh

Hi,

If you want to create a kernel module, you can use that kind of recipe

meta-x-bsp/recipes-kernel/kernel-module/kernel-module-modulename.bb:

SUMMARY = "Kernel loadable module"
DESCRIPTION = "This package includes loadable module"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://COPYING;md5=a04ba2d94725e7270af091f1f1cb6580"

PV .= "+git${SRCPV}"

SRCREV = "e26baba25fa792730d09c6e5334814b3037e7bc7"
SRC_URI = "git://url/modulename.git"

S = "${WORKDIR}/git"

inherit module

KERNEL_MODULE_AUTOLOAD = "modulename"

If it ok for you ?
Best Regards,
Vincent
