Hi,
We are using MPC5645s controller in our project, with that we are using 64 MB external DDR memory.
We are utilizing only 8 MB to display image.
We want to utilize more of the DDR memory instead of internal RAM by allocating global data and heap section.
Can you give us some example code or way to use external RAM to its full capacity.
dtb-$(CONFIG_ARCH_MXC) += imx8mm-ddr4-evk.dtb
DDR configuration can be adjusted using the RPA tool provided by NXP
