Using the Link Application to RAM feature in MCUXpresso for VSCode

Hi All

I am developing a system using Zephyr OS on i.MXRT1072

In MCUXpresso IDE, I can use the "Link application to RAM" function to load the binary directly into RAM for testing without programming it in flash. I want to know how to do this in MCUXpresso for VSCode.

After researching the documentation, I found that using the "Link application to RAM" feature in MCUXpresso for VS Code requires directly specifying a memory area to the project's build system. However, trying various methods takes a lot of time and doesn't make any progress.

I think NXP headquarters is also developing Zephyr-related projects by downloading them to RAM. Could you provide an example of how to run the "hello_world" sample in NXP Zephyr V4.1 using NXP Link2 in RAM?

Thank you

Hi @AndrewChoi,

Please take a look at the following discussion, where my colleague Derek Snell details the process, he did to run an application from RAM on the RT1024. Run entire application from RAM · zephyrproject-rtos/zephyr · Discussion #36800 · GitHub. Altough a different device, it is still applicable for the RT1170.

BR,
Edwin.
