用led双核可以，这个demo就不行了，怎么解决啊

teddy · 发表于 2015-11-3 13:47:21

内存不够，先关掉一些进程，像matrix-gui，然后在运行你的双核程序。

你可能用的是128M的内存，所以可能系统内存不够，你用free看看当前系统内存是不是不够。

还是不行

teddy · 发表于 2015-11-3 09:14:02

需要配置vpif的缓存；
1.vpif capture模式选择，vpif_capture_format值：
HDTV：预留
SDTV: TL5147
RAW:TL2640
2.（ov2640配置分辨率为640*480 = 640*480*2 = 614400）
vpif_capture.ch0_bufsize=614400
例如：
U-Boot > setenv optargs ${optargs} vpif_capture_format=RAW vpif_capture.ch0_bufsize=614400
说明：optargs变量为参数添加变量，主要给需要添加参数传递给内核。
setenv optargs ${optargs} vpif_capture_format=SDTV vpif_capture.ch0_bufsize=614400
