Hi.

We use i.mx6 ( IMX6DL ).

We configured boot from eMMC   flash. From   mmcblk3boot0  or  mmcblk3boot1.

At first we use   Linux kernel  3.10.53.

In the File System  we see files: boot_bus_config ,  boot_config , boot_info .

 

By this files we change boot . From mmcblk3boot0 or mmcblk3boot1.

This boot from mmcblk3boot0 .

echo 8 > /sys/devices/soc0/soc.0/2100000.aips-bus/219c000.usdhc/mmc_host/mmc3/mmc3:0001/boot_config

 

This boot from mmcblk3boot1 .

echo 16 > /sys/devices/soc0/soc.0/2100000.aips-bus/219c000.usdhc/mmc_host/mmc3/mmc3:0001/boot_config

 

 

Now we use Linux kernel 4.1.15.

We have a problem . We not see files: boot_bus_config ,  boot_config , boot_info .(??????)

How we can configure our system for boot from eMMC from  mmcblk3boot0  or  mmcblk3boot1.

 

Best regards.
