Hi NXP,

I have the okimx6ull-s system on module.

I'm trying to program emmc but I'm getting an error:

my yocto project file:

	$ repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-kirkstone -m imx-5.15.52-2.1.0.xml
	$ repo sync
	$ DISTRO=fsl-imx-wayland MACHINE=imx6ull14x14evk source imx-setup-release.sh -b build
	$ bitbake imx-image-core

How do I create my own yocto project for my custom card?

Hello,

You have to adapt the driver and its programming to your pcb, check your device tree the locations of all modules.
