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

[Guillaume Fournier]

To try and figure out where the problem resides, I started from scratch.

1) got latest BSP: repo init -u
https://github.com/Freescale/fsl-community-bsp-platform -b dizzy
2) modified local.conf so MACHINE is imx6dlsabresd
3) On "bitbake meta-toolchain", I got these QA warnings:
WARNING: QA Issue: gcc-cross-canadian-arm: found library in wrong location:
/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnuea

bi/gcc/arm-poky-linux-gnueabi/4.9.1/liblto_plugin.so.0 [libdir]

I'm not sure these are relevant to my problem so I kept on going.

4) got latest u-boot: git clone https://github.com/Freescale/u-boot-fslc.git
5) started a fresh shell, ran toolchain environment script, cd to
u-boot-fslc
6) make LDFLAGS="" CC="$CC" mx6dlsabresd_config
7) make LDFLAGS="" CC="$CC" u-boot.imx
8) Programmed u-boot.imx on SD card: cfimager -f u-boot.imx -raw -offset
1024 -d d
9) Try to boot target -> not booting, no UART output

Could the problem be related to the Device Configuration Data since u-boot
spits out something on the UART pretty early ?
