Can the SD card example for RT1052 use mimxrt1052xxxxx_flexspi_nor_sdram.icf?

[1914795885]

Hello

I wanted to use the sd card function of RT1052, but found that mimxrt1052xxxxx_flexspi_nor_sdram.icf was not used in the example.When using mimxrt1052xxxxx_flexspi_nor. icf, the sd card can work normally, but when using mimxrt1052xxxxx_flexspi_nor. icf, the sd card cannot work.

Below is the print information using mimxrt1052xxxxx_flexspi_nor.icf

Hi main i

Are you using the latest SDK (v2.5)? I have checked the example code that you mentioned, but there isn't any  mimxrt1052xxxxx_flexspi_nor_sdram.icf. I only see the mimxrt1052xxxxx_flexspi_sdram.icf which works correctly in my side.

I also checked the other ICF files from the IAR SDK package and all of them work correctly.

Hi Jorge Alcala

I want to use spifalsh and sdram in the SD card example.

Hi main

Sorry, the name of the .icf that I put was incorrect, the .icf that is included in the example is  mimxrt1052xxxxx_sdram.icf. This example code will run in RAM ITCM, but it will use the SDRAM for data memory, including STACK, HEAP, ZI, and RW memories, this example does not boot in the SDRAM. You can find the example in the latest SDK 2.5.

Could you clarify what you need? do you need that the code run in a NOR flash and uses the external SDRAM for data memory?

Hi Jorge Alcala

I wanted to make a video recorder application that could save video to a local sd card, so I needed NOR flash and external sdram. Can it be achieved by modifying XXX. Icf?

Hi main i

Ok, thanks for the clarification. So you actually don't need to boot from SD, you can actually boot from the external hyperflash or NOR memory and then save the image in the SD using the SDRAM as data memory. This application is actually in the AppNote;

Developing a Camera Application with i.MXRT Series

https://www.nxp.com/docs/en/application-note/AN12110.pdf 

It was developed in IAR, but it should be a straightforward migration to a new IDE.

Hope this could help you, Please let me know if you have any other question.

Hi Jorge Alcala

Thank you very much, this is very helpful to me, but I did not find this source code in sdk_2.5.0_evkb-imxrt1050, can you send me the source code in a document?

Hi main i

No, this example code is not included in the SDK software, but you can find it associated with the application note:

Hope this helps
