U-boot Error for TI Jacinto 6+ board

Board Integrations
,
1

Hi there,

I am trying to integrate mender with the TI Jacinto 6+ board (dra7xx).
I have modified the u-boot by applying the generic Mender patches from Github ( https://github.com/mendersoftware/meta-mender/tree/master/meta-mender-core/recipes-bsp/u-boot/patches ) and have made board specific changes as per mender documentation. (Manual U-Boot integration | Mender documentation). I have cross compiled and generated the resultant u-boot.img and used it with the mender-converted image to boot the board but am getting the following error:

Welcome to minicom 2.7.1

Have you tried stopping the auto-boot, and having a look at the partitions?
