I am trying to load the kernel using uboot and I get a data abort exception. I have followed the procedures same as what is given by Freescale. uboot version : uboot-imx-rel_imx_3.10.53_1.1.1
I have tried putting $(PF_NO_ALIGNED) in the config.mk of the uboot but there is no luck. How can I debug this?
I get the following message:
Normal Boot Hit any key to stop autoboot: 0 reading uImage 4659752 bytes read in 225 ms (19.8 MiB/s) reading imx6dl-sabresd.dtb 49157 bytes read in 19 ms (2.5 MiB/s) ## Booting kernel from Legacy Image at 12000000 ...

and my loadaddr is 0x12000000
What seems to have gone wrong? I have booted this properly with one set of boards where the UART was uart3. The newer boards have UART as UART1 and that is the only change done. Also I find that exception happens when the kernel entry point function pointer gets called in uboot.
