openrex imx6 does not respond

[renato]

Hello everyone,

i have a problem with openrex imx6, i could don't access to kernel (bootmmc not found). So i tried to update the uboot, following this guide
"http://www.imx6rex.com/open-rex/software/how-to -uboot-compile-flash-update-boot / # help_uboot ".
But I did not succeed, and now I can not access openrex by serial. so I do not know how to do it again to change settings.
Can I restore the original settings on openrex?? or maybe there are some procedures I can use to unlock the serial?
thanks
