用华恒9200的板,板子启动时有提示:
...
colour dummy device 80x30
...
S1D13XXX: Phys address:C480F000 Phys Reg address:C480D000
Console: switching to colour frame buffer device 80x30
fb0: s1d13xxx frame buffer device
Display 640 x 480 16Bpp
...
我用的是240x320的屏,是不是和内核的framebuffer配置有关?
在内核源码driver的头文件中有现在的显示芯片的参数:
我用的是epson显示芯片
头文件是/HHARM9200/linux-2.4.19-rmk7/drivers/video/epson/s1d13506.h
...
// CRT: (active) 640x480 60Hz (PCLK=CLKI2=25.175MHz)
// Memory: 50ns EDO-DRAM 2-CAS#: 8ms refresh (MCLK=BUSCLK=33.333MHz)
#define S1D_DISPLAY_WIDTH 640
#define S1D_DISPLAY_HEIGHT 480
#define S1D_DISPLAY_BPP 16
...
向高手请教...
此致鞠躬x99 |
