1.编译 Rowboat Froyo+DSP
# make TARGET_PRODUCT=omap3evm [OMAPES=(2.x|3.x|5.x)]
OMAPES=2.x, for OMAP3530 ES1 or ES2;
OMAPES=3.x, for OMAP3530 ES3.0;
OMAPES=5.x, for DM37x
2.uboot参数
# setenv bootcmd 'mmc init; fatload mmc 0 80800000 uImage; bootm 80800000'
# setenv bootargs 'mem=76M@0x80000000 mem=128M@0x88000000 console=tty0
console=ttyS0,115200n8 androidboot.console=ttyS0 root=/dev/mmcblk0p2 rw rootfstype=ext3
init=/init rootwait ip=off omap_vout.vid1_static_vrfb_alloc=y
omapdss.def_disp=dvi omapfb.mode=dvi:1280x720MR-16 mpurate=1000'
OMAP3_EVM# saveenv
======================================================================
256M内存:
37x
mem=68M@0x80000000 mem=128M@0x88000000
35x
mem=104M@0x80000000 mem=128M@0x88000000
512M内存:
37x
mem=68M@0x80000000 mem=384M@0x88000000
35x
mem=104M@0x80000000 mem=384M@0x88000000
3.针对EMA37x的DSP uboot启动参数:
setenv defaultdisplay lcd070
setenv mmcargs 'setenv bootargs console=${console} vram=${vram} omapfb.mode=dvi:${dvimode} omapdss.def_disp=${defaultdisplay} root=${mmcroot} init=/init mpurate=${mpurate} rootfstype=${mmcrootfstype} boardmodel=${boardmodel} omap_vout.vid1_static_vrfb_alloc=y mem=68M@0x80000000 mem=384M@0x88000000'
4.编译DM37x 的dvsdk需要Ubuntu 10.04以上版本。
5.装busybox,播放dsp会出现问题,原因估计是busybox的sh不兼容,导致解析dsp的sh脚本出现问题。
