Hi,

I have I.MX53 EVK board(MCIMX535DVV1C). I want to use Yocto build system with 2.6.35 Kernel.

Can you please provide the link to download Yocto for I.MX53 Evk(MCIMX535DVV1C).

Hi Bio,

Thanks for the info, I have downloaded BSP as per the steps at http://freescale.github.io/#download and executed following commands.

ubuntu-OptiPlex-7010:~/fsl-community-bsp/build$MACHINE=imx53qsb

ubuntu-OptiPlex-7010:~/fsl-community-bsp/build$source setup-environment build

ubuntu-OptiPlex-7010:~/fsl-community-bsp/build$bitbake core-image-minimal

Initially I got the following error, but issue solved after installing libsdl using "sudo apt-get install libsdl1.2-dev"

----------------------------------------------------------------------------------------------------------------------------------------------------------

WARNING: Host distribution "Ubuntu-12.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.

ERROR:  OE-core's config sanity checker detected a potential misconfiguration.

    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).

    Following is the list of potential problems / advisories:

    libsdl-native is set to be ASSUME_PROVIDED but sdl-config can't be found in PATH. Please either install it, or configure qemu not to require sdl.

Now I am getting checksum error for gcc-4.9.2

If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe:

Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.

In poky/meta/recipes-devtools/gcc/gcc-4.9.inc file the checksum value is updated as shown below.

SRC_URI[md5sum] = "4df8ee253b7f3863ad0b86359cd39c43"

Do I need to try with different GNU_MIRROR or checksum. Can you please guide to fix this issue.

It is working fine when I use direct line.

In office network few of the URLs are blocked, so may be while trying with mirrors it is giving checksum mismatch issue.
