Hi ,

Can Any one help me to get the Kernel source code for i.Mx53 by providing the link below

and the procedure to apply freescale patch.

Thank you,

If you go to the top level NXP i.MX53 Product Page you can see a link to "i.MX53 Current Software Updates and Releases".

That page also has links to the Documentation Bundles.

The git tree is very useful. You can clone and branch from here:

linux-2.6-imx.git - Freescale i.MX Linux Tree

That gets you the full Linux sources with all patches applied, who applied them, where else they were applied and so on. I would suggest you clone that tree to your computer and then start developing on a branch of that. That assumes you know how to set up a compiler and so on.

The "2.6.35_maintain" is the latest branch for the i.MX53.

It may be easier for you to use the Freescale development tools. The packages downloadable from the link above should contain these, but as I'm using a separate build system I don't know for sure. The Development Kits come with CDs of the software.

The last supported release of Linux for the i.MX53 is quite old (2.6.35) and has a lot of bugs in it. I've been posting lists of bugs as I find them and patches to fix them here:

Submit i.MX53 & i.MX28 Linux kernel patches

Hello,

From "i.MX53_START_Linux_BSP_UserGuide.pdf" :

2.1 Setting Up the Linux Host

See “ltib_build_host_setup.pdf” to setup the Linux host server.

2.2 Installing and Building LTIB

To install and build LTIB, follow the steps below:

NOTE

In some Linux systems, the following procedure must be done

with root permissions. However, these instructions are for

performing the procedure “not as root”.

To run LTIB, some host packages are needed. If any error

related to a host package is raised, install the host package.

1. Remove all previously-installed packages in /opt/freescale/pkgs/.

2. Install the LTIB package not as root:

tar zxf <ltib_release>.tar.gz

./<ltib_release>/install

3. Install the patches located in the patches.tar.gz file.

This command installs LTIB to your directory.

4. Build LTIB:

cd <LTIB directory>

./ltib -m config

5. Select platform to Freescale iMX reference boards and exit, saving the changes. At the

next menu, select platform type as imx5x and package profile. Exit and save

changes. Please note that only the profiles of Min profile, FSL gnome release

packages and mfg firmware profile pass build tests.

6. To build U-Boot for MX53 START board, select “Choose your board for u-boot” as

“mx53_loco”. Please note this option is only for U-Boot. For kernel image, current

default kernel configuration can build the same images for all i.MX5x parts boards.

--- Choose your board

board (mx53_loco) --->

7. Run the following command:

./ltib

When this procedure is completed, the kernel image and the U-boot images are located at:

rootfs/boot/

8. Input the following command to get LTIB command help:

./ltib -help

/* Get the source code of one package */

./ltib -m prep -p <package name>

/* Build one package */

./ltib -m scbuild -p <package name>

/* Install one package to rootfs */

./ltib -m scdeploy -p <package name>

NOTE

If your system is not using a touchscreen as a primary device

you should remove touchcreens from the kernel configuration.

• Run ./ltib –m config

• Select Configure the kernel

• Run ./ltib again

• Select Device drivers

• Select Input device support

• Deselect touchscreens

Have a great day,
Yuri

Hi,

To build only the kernel (as one of packages) :

/* Get the source code of one package */

./ltib -m prep -p kernel

/* Build one package */

./ltib -m scbuild -p kernel

/* Install one package to rootfs */

./ltib -m scdeploy -p kernel

Regards,

Yuri.

Hello,

According to IPULIB documentation :

"The source codes of the IPU library are located into imx-lib LTIB package [...]

.To get its source code, run ./ltib -m prep -p imx-lib

Then cd rpm/BUILD/imx-lib-<version>/ipu"

Regards,

Yuri.
