Generating the DCD (Device Configuration Data) for u-boot in IOMux Tool?

sivaalagarsamy · ‎05-23-2014

The u-boot has a board configuration file which has DCD data in the following format.

ADDRESS-TYPE ADDRESS VALUE

I am using the IOMux Tool to configure the IOMUX.

Is there a easy way to generate the DCD data from the IOMux Tool?

Thanks,

Siva

Hi,

Is there another way to generate DCD data ?

Do you have examples DCD for various DDR hardware configurations or an application note dealing with ?

Mine is single chip MT41K128M16 (16M*16*8banks = 256MB) and I try to load correct configuration without success for the moment ...

Thanks,

Martin

Thanks, It helps a lot !

As a note, for other new designs : Don't forget to use MX6_MMDC_P0_MPODTCTRL = 0x00011117 instead default 22227 generated by script aid XLS.

I've found it "recommanded for new designs" in MX6DL_SabreSD_DDR3_register_programming_aid_v1.5.inc
