Assembled a new test image with the meson 
branch-mx-integration-4.12-20170507 ,
included in the config file the option CONFIG_MMC_MESON_MX_SDIO=y and 
CONFIG_PHY_MESON8B_USB2=y .
Tried to run from SD card new version, yet the result is the same as 
before. I do not consider ?
What compiler is better to use 4.9.4 or 6.3.1 ?
