Hi,

here you are my configuration:

#define CONFIG_EXTRA_ENV_SETTINGS \
    "image=zImage\0" \
"console=" CONFIG_CONSOLE_DEV "\0" \
"fdt_file=imx6q-tibidabo.dtb\0" \
"fdt_addr=0x14000000\0" \
"mmcdev="__stringify(CONFIG_SYS_MMC_ENV_DEV)"\0" \
"mmcpart=" __stringify(CONFIG_SYS_MMC_IMG_LOAD_PART) "\0" \
"mmcroot=" CONFIG_MMCROOT " rootwait rw\0" \
"mmcautodetect=yes\0" \
"mmcargs=setenv bootargs console=${console},${baudrate} earlyprintk " \
"root=${mmcroot}\0" \
"loadimage=fatload mmc ${mmcdev}:${mmcpart} ${loadaddr} ${image}\0" \
"loadfdt=fatload mmc ${mmcdev}:${mmcpart} ${fdt_addr} ${fdt_file}\0" \

#define CONFIG_BOOTCOMMAND \
    "run mmcargs; " \
"run loadfdt; " \
"run loadimage; " \
"bootz ${loadaddr} - ${fdt_addr}; "\

it is easy.

I tried to put earlyprintk but i didn't see any output.
