We have a custom board which is based on the i.MX6 EVK board.

The difference is that we do not have SD card and we use eMMC instead

We are trying to  upload Linux version fsl-yocto-L4.1.15_1.2.0 to the RAM using MFG tool version L4.1.X_1.2.0_ga

First we used the u-boot and BSP came with the MFG tool, than we compiled the BSP and u-boot for MFG tool and used them.

The MFG tool stops last indication is "Jumping to OS image". we tried to load the u-boot by itself and the last MFG indication was "Jumping to u-boot image". nothing after that.


in the MFG log all operations are successful until the jump:

My win 7 computer is connected to UART1 on the board using USB to UART converter but nothing is shown in the terminal. should I get something?


Any idea what is the problem? is there a way to debug it?
