How to set up ram in the MCU xpresso ide compilation environment

[gaobiao315]

hi all：

    Now I use McUxpresso IDE for debugging. The SRAM in MK21DN512AVMC5 chip has 64K, which is divided into 32K for SRAM_U and 32K for SRAM_L. Now my variables exceed 32K, how to allocate variables? Now the compiler prompts the following error:

Hello duan jz 

I see that the error is caused because all the data is placed in Upper SRAM. To avoid this you can refer to this post: https://community.nxp.com/docs/DOC-335283

Let me know if this is helpful, if you have more questions do not hesitate to ask me.

Best regards,

Omar
