Hi
I have a custom board based on an iMX6UL processor. I have used the DDR Stress Tester V2.51 to determine the DDR3 calibration values. Now I have the values, how do I include them into my linux build? Specifically, which file do I need to modify with the calibration values?
I am using the Yocto Project, build (imx-3.14.38-6UL_ga).
I have tried to find the file, the closest I found was a file called plugin.S which defines an assembler macro (imx6ul_ddr3_arm2_setting) which loads the DDR control registers. Is this the file to use?
Thanks for your help
Steve
New configuration settings can be added to uboot file :
uboot/.. mx6q_sabresd/flash_header.S
Hello,
Please use Chapter 1 (Porting U-Boot from an i.MX 6/7 Reference Board to
an i.MX 6/7 Custom Board) of "i.MX_BSP_Porting_Guide.pdf" in Linux docs.

Have a great day,
