all,
hi, when I boot my system, there are no output on the screen. I choice the framebuffer and my monitor card is ATI PAGE 128 PCI, qt/e GUI. When i compile the kernel, the boot logo and aty 128fb has be compiled into kernel patched with videoboot, and x86emu. The video parameters set:
video=aty128fb:640x480-16@7.
The kenel can recognize the monitor card, and the frame buffer device has run.
The output showed below:
videoboot: Booting PCI video card bus 0, function 0, device 6
aty128fb: Found Intel x86 BIOS ROM Image
aty128fb: Rage128 BIOS located
aty128fb: Rage128 RK PCI [chip rev 0x2] 32M 64-bit SDR SGRAM (2:1)
fb0: ATY Rage128 frame buffer device on Rage128 RK PCI
My problem is there is no output on the monitor,and cannot see the penguin boot logo.
I also run a program to test the framebuffer, which can read data from the fb. After running the qt/e program, which can run scussessfully, there is no output.!
The test program reading data are showed below;
id = ATY Rage128
depth = 16
smemlen = 33554432
line_length = 0
FB_TYPE_ = 0
type_aux = 0
FB_VISUAL_ = 3
xpanstep = 8
ypanstep = 1
ywrapstep = 0
mmio_start = bbffc0000d
mmio_len = 8192
accel = 32
xres = 640
yres = 480
xres_virtul = 640
yres_virtul = 480
xoffset = 0
yoffset = 0
bits_per_pixel = 16
My linux kernel is DENX 2.6.19.
What can I do to make my system output into monitor.?
