Yocto not booting on i.mx233 Custom Board

[yanir]

Hi I am trying to get yocto up and running on my custom board based on the i.mx23evk. The board works and boots the freescale provided demo image. My board is closely based on the EVK design with some features removed. I have a debug serial port, 24bit lcd with touch and some other things.

Any help will be greatly appreciated.

Some details:

I built the core-image-minimal recipe.

My local.conf file:

MACHINE ??= 'imx23evk'

DISTRO ?= 'poky'

PACKAGE_CLASSES ?= "package_rpm"

EXTRA_IMAGE_FEATURES = "debug-tweaks"

USER_CLASSES ?= "buildstats image-mklibs image-prelink"

PATCHRESOLVE = "noop"

BB_DISKMON_DIRS = "\

    STOPTASKS,${TMPDIR},1G,100K \

    STOPTASKS,${DL_DIR},1G,100K \

    STOPTASKS,${SSTATE_DIR},1G,100K \

    ABORT,${TMPDIR},100M,1K \

    ABORT,${DL_DIR},100M,1K \

    ABORT,${SSTATE_DIR},100M,1K"

CONF_VERSION = "1"

BB_NUMBER_THREADS = '2'

PARALLEL_MAKE = '-j 2'

ACCEPT_FSL_EULA = "1"

Here is the output from the debug port when attempting to boot on my custom board:

It needs to compare your schematic to check what changes you did; these might have impact in the board boot. I am also backporting  to the U-Boot a serie os patches which improves DDR stability and this might help as well.

Check if mmc had any change in your layout as it seems to fail to probe it.

You need to adjust the IOMUX for your custom design to make it work.

This needs to be done in U-Boot source code and I'd suggest you to make a new board, not hack on mx23evk code, so you make it easy for further upgrades on it.
