How to use customized defconfig in Apalis ixm6

Technical Support

We have made some changes in kernel and so we have new customized defconfig.

We have followed below folder structure:

├── conf
│   └── layer.conf
├── README.md
├── recipes-kernel
│   └── linux
│       ├── linux-toradex
│       │   ├── 0001-gps-gsm-integration.patch
│       │   ├── 0001-WIFI--integrated.patch
│       │   └── defconfig
│       └── linux-toradex_4.9-2.3.x.bbappend

Our linux-toradex_4.9-2.3.x.bbappend looks like below:

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI += "file://0001-gps-gsm-integration.patch \
            file://0001-WIFI--integrated.patch \
            file://defconfig"

Our layer.conf is :

BBPATH .= ":${LAYERDIR}"

BBFILES += "${LAYERDIR}/recipes-*/*/*.bb ${LAYERDIR}/recipes-*/*/*.bbappend"

BBFILE_COLLECTIONS += "meta-mylayer"
BBFILE_PATTERN_meta-mylayer := "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-mylayer = "99"

However when we compile using ‘bitbake -k console-tdx-image’ our defconfig changes doesn’t reflect but other 2 patches gets applied correctly.

What could be the wrong here ? Please guide us.

You should probably put defconfig in machine specific subfolder in linux-toradex folder.

Check this answer.

Dear @mlinar and @jaski.tx

I tried above suggested answer but it did not help me.
I changed my folder structure as below:

├── conf
│   └── layer.conf
├── README.md
├── recipes-kernel
│   └── linux
│       ├── linux-toradex
│       │   └── apalis-imx6
│       │       ├── 0001-gps-gsm-integration.patch
│       │       ├── 0001-WIFI--integrated.patch
│       │       └── defconfig
│       └── linux-toradex_4.9-2.3.x.bbappend

My .bbapend looks like below:

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI += "file://0001-gps-gsm-integration.patch \
            file://0001-WIFI--integrated.patch \
            file://defconfig"

I can see that .patch are getting applied but not the defconfig.
Could you please let me know how to achieve this ?

Hi @amit251291 ,

Could you please try by using the below config.

  • Use only your two patches in SRC_URI,
    SRC_URI += "file://0001-gps-gsm-integration.patch \
    file://0001-WIFI–integrated.patch "

  • Place your patch under linux-toradex/ directory. (not in apalis_imx6)

  • Place your defconfig in linux-toradex/apalis_imx6/defconfig .

Now build the image.
For debugging purposes, you can also see in tmp/ directory under your build.

Best Regards,
Deven
