I am using ddr memory for cortex-M4 on imx7d based custom board. There are only 3 scf files available for ddr configurations in the FreeRTOS source code.

 

MCIMX7D_M4_ddr-512K.scf
MCIMX7D_M4_ddr-1M.scf
MCIMX7D_M4_ddr-128K.scf

 As i am using arm-gcc compiler, I have made few changes in ddr linker file to use the 1MB of ram by taking reference of scf file.

 

My question is can i use more than 1MB of RAM for cortex-M4 because i find scf file for using RAM upto 1MB?

I am not able to find related info from the reference manual.
