I have downloaded and built fsl_release_bsp according Freescale_Yocto_Project_User's_Guide.pdf in fsl-yocto-3.14.28-1.0.0.gz recently. I used to build my linux os in BSP3.0.35.
I used DDR3 script aid on the following URL, and got a calibration data：Freescale i.MX6 DRAM Port Application Guide-DDR3 . I update the calibration data to <u-boot directory>/board/freescale/mx6q_sabresd/flash_header.S for the 3.0.35 BSP. But for the yocto bsp, I can't find the flash_header.S and what file should I apply the calibration data?
