Good day everyone,
I am using Overo Water COM which has a 512M and would like to unsure if setting my bootargs environment like this is ok:
" setenv bootargs "console=ttyS2,115200n8 mpurate=720 vram=12M
mem=96M@0x80000000 mem=384M@0x88000000 omapfb.mode=dvi:1024x768MR-16@60
omapdss.def_disp=dvi root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait" "
The next question is how to allocate the Kernel and CMEM memory using the "pools=1x????? phys_start=0x???? and phys_end=0x???" such that it will tell the cmem on where to start and stop!
I came across this example from https://groups.google.com/forum/?fromgroups#!topic/beagleboard/ccq2jAd2e-w as listed below:
0xC0000000 - 0xC4FFFFFF for kernel (80M)
0xC5000000 - 0xC5FFFFFF for cmem, (16M)
In this case, bootargs was mem=80M for kernel and in cmem, phys_start=0xc5000000 phys_end=0xc5ffffff.
I am trying to implement this method instead of running mmcargs "Overo # run mmcargs" in order to avoid the Kernel mismatched version problem since I am using kernel 3.2.0 and wouldn't like to go for kernel 2.6.34
Thanks in advance,
