[meta-freescale] Unable to get u-boot running on i.MX6 SABRE for Smart Devices Eval Board

[Guillaume Fournier]

Fabio,

The ultimate goal is to have a cross-compiler build environment that works for both u-boot and kernel development.  For now, I used Yocto to generate the toolchain (using meta-toolchain as specified in my first post) as described in section 3.4 of the Yocto Project Application Developer's Guide.  Following your lead I did use "bitbake core-image-base" to generate an image and burned core-image-base-imx6dlsabresd.sdcard to an SD card using:
cfimager -f core-image-base-imx6dlsabresd.sdcard -raw -d d

I used cfimager which is a tool that comes with IMX_6DL_6S_MFG_TOOL since I don't have physical access to a linux box.  The board boots up fine but this is not the goal I seek.  I want to get a working cross-compiling toolchain so I can build u-boot and the kernel outside of Yocto.  I understand the subject of this post is therefore a bit misleading since u-boot does boot when using Yocto build output...  It just doesn't when using the cross-compiling toolchain.

As a side note, I have also downloaded fsl-image-multimedia-imx6dlsabresd.sdcard from http://ci.ossystems.com.br/public/fsl-community-bsp/daisy/76/framebuffer/imx6dlsabresd and burned it to an SD card and it too works fine.

Could you try to flash the .sdcard image directly to the SD card and boot from there? That would be a quicker method.

There are some pre-built .sdcard images available at http://ci.ossystems.com.br/public/fsl-community-bsp/ that you could quickly try.
