[meta-freescale] Cannot boot after the last update...

[Konstantin Kovalev]

Dear Otavio,
Thanks for your quick response! After some attempts I have found the solution. The problem was in the variable "mmcroot". I've just changed the default value "mmcblk1p2" to "mmcblk0p2" and it works. However, the system stops booting on request "imx6qsabresd login:" and doesn't response on keyboard, touchscreen, and mouse. Unfortunately, my adb console doesn't show any errors on that stage. Probably I did not solve all errors in my u-boot default variables. This is my u-boot environments:
