IMX6DL JTAG DDR3 Calibration and stress test UART problem

Hi,

I am using JLink Debugger to calibrate 2GB DDR3 on IMX6DL flyby routed. I am using UART 4 as my debug port. I created a single .JLink script(attached), in which I did:

1. created the ddr_init.inc script

2.converted it to JLink script

3. added UART4 initialization (IOMUX settings for UART 4 , desabbled UART 1 , enabled UART4)

4.Load the ddr-test-uboot-jtag-mx6dl.elf

5.run

The script loads without any problems!

The problem is that I dont see anything on Uart4 console. If I set the IOMUX to UART 1, I still dont see anything on my console. Attached is my script

Thanks,
