We configure DDR timing and configuration related registers in the imximage.cfg file. i want to know how these values will be written to the registers? Where the content of imximage.cfg file resides in the built u-boot.imx? At what stage of booting this values will be written to the register?

Hi jags

imximage.cfg (dcd header) contains data processed during boot by

iROM, using procedure described in sect.8.6.2 Device Configuration Data (DCD)

i.MX6SL Reference Manual (rev.2  6/2015).

Sect.8.6.1 Image Vector Table and Boot Data shows how this data is stored in image.

Best regards
