imx7ulpevk memory

Dear All,

I have a imx7ulpevk board. I changed the on board DRAM with a 4Gb LPDDR3.  I would like to test the memory as much as I can from the A7 CPU core. When I boot up the A7 core with Linux, I found there are some space seems to be reserved for the M4 or for A7/M4 communication . If this is true, is there any method to change? Will it work if I delete the rpmsg reserved memory in the dtsi file?

Regards,

Ka-Yi

Dear Igor,

Thank you for your quick response. When I modified the imx7ulp.dtsi as attached then copy back to :

work/imx7ulpevk-poky-linux-gnueabi/u-boot-imx/2018.03-r0/git/arch/arm/dts/imx7ulp.dtsi

it seems fine to bitbake but the result turns out the same. Did I modify the wrong file?

Hi Ka-Yi

one can look at i.MX7D example, without rpmsg_reserved :

imx7d.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel
