iMXRT 1064 EVK SDRAM for images

[anujtanksali]

Hello,

I am currently working on IMXRT 1064 EVK board. I will be using Emwin graphical library for GUI development.

There is a SDRAM on board the EVK which i wanted to use for images and fonts. I wanted to know how can i initialize the SDRAM with constant values..

Thanks,

Regards,

Anuj

Hi

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
To make it, I'd like you to utilize the DCD feature which can initialize the SDRAM during the start-up process and you can learn the detail information about this feature via reviewing the below figure.

In further, in the SDK' demo, it allows the developer to enable or disable the DCD feature via setting the XIP_BOOT_HEADER_DCD_ENABLE value as Figure 2 shows.

Have a great day,
