Hi, I'm using SabreSD board with SDK-3.0.35_4.1.0 and try to downsize it's memory to 512MB, to see if it works fine for our cost down version product.
I re-compile u-boot with change the define "PHYS_SDRAM_1_SIZE (1u * 512 * 1024 * 1024)" to make SabreSD boot with 512MB.
and use gplay to see if VPU works normally, but kernel continue output: "Physical memory allocation error!".
I change back uboot to use 1G memory and gplay works fine. I think I may need guides to setting my SabreSD board correctly with 512MB RAM.
below is my bootargs:
console=ttymxc0,115200 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 fbmem=64M video=mxcfb0:dev=hdmi,1024x768M@60,if=RGB24,bpp=32 quiet mem=512M ldo_active=on
and my GPU reserved 32M, VPU reserved 128M. any suggestion would be appreciated, thanks.
