DCD (Device Configuration Data) for i.Mx6 QuadCore

maheshkumarkoda — Tue, 19 Jan 2016 10:08:34 GMT

Is it possible to modify DCD (Device Configuration Data)? or DCD is hard coded for internal ROM to boot up?

Customized Hardware board with i.Mx6 Quadcore is used in my project.

Also put some light on how DCD is related to pNOR flash with an example?

Thanks a lot :smileyhappy:

Hi Mahesh

for parallel NOR it is placed on 0x1000 bytes offset and described in

sect.8.6.2 Device Configuration Data (DCD)

for parallel NOR example one can look at sect.4.4.1.4 Flashing U-Boot on Parallel

NOR from U-Boot attached Linux Guide

Best regards

igor
