Hello,
Yes, some differences may take place, therefore, at least check the U-boot DCD.
Use U-boot porting chapter of "i.MX_BSP_Porting_Guide.pdf".

Hi,Yuri

Hello,
As we can see on the oscilloscope waveforms some portion of boot data
is loaded to DRAM, which should be preliminary initialized, using the DCD.
If memory is not initialized correctly, boot issues can take place.

Hello,
Please check memory initialization in U-boot.
Information about it may be found in U-boot porting chapter of "i.MX_BSP_Porting_Guide.pdf".
The following resource may be helpful:
i.MX6SL DDR3 Register Programming Aid
Also, try to run the DDR Stress test (JTAG or USB downloader based versions).
