RT1020 SDK: evkmimxrt1020_sdram_ini_dcd.c or evkmimxrt1020_sdram_ini_dcd.h missing?

[klau]

Hi,

I created a RT1020 SDK, more than once, from a button in the middle of this page labelled as "GET MCUXPRESSO SDK".
https://www.nxp.com/document/guide/get-started-with-the-mimxrt1020-evk:GS-MIMXRT1020-EVK

I believe that these files are needed to access SDRAM (external DRAM, not on chip RAM).
Am I correct?

If yes, could you show me how to get these two files please?
If these are missing from SDK, could you show me how to add them?

Thanks,
Kevin

Hi,

Please refer to this post,
https://community.nxp.com/t5/i-MX-RT/How-to-generate-dcd-bin-file-for-mfgtools-use-to-flash-RT1020/m...

In the middle of that post, you will find 

"For an example, look at dcd_data[]

in “evkmimxrt1020_sdram_ini_dcd.c” of i.MX RT1020 SDK."

I could NOT find it in my SDK.

Could you help locate it please?

Thanks,
Kevin

Hi Kevin,

Please make sure you are selecting all the middleware when you build your SDK. Once you have done this you will find the files in the following path.

SDK_2.8.2_EVK-MIMXRT1020\middleware\safety_iec60730b\boards\evkmimxrt1020\xip

Regards,

Felipe
