PCI to Parallel for PowerPC
hi, all I bought a SMC1500 stepper motor card. And it can connect with host through parallel port. My target board is PowerPC 440, which hasn't parrallel port. So I bought a PCI to Parallel line for SMC1500. But when I run the stepper motor, I find it's not stable. I doubt there are somthing wrong with my PCI to Parallel line. So I beg somebody can tell me where I can bought the appropriate conversion line from PCI to parallel, and does somebody give me some idea about how to control my stepper motor through PowerPC 440? thx all Best Regards!

ring on PowerPC
Hi, everyone As we know, the program on the X86 can run on the differnt ring(0, 1, 2, 3) and the linux kernel run in the ring 0 and user program in the ring 3. And now I want to know wether there is a simple mechanism on the PowerPC architecture? thx all! best regards!

powerpc 440 monitor program
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:[EMAIL PROTECTED] 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 = bbffcd 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.? best regards! buroc -- Add: Tianshui South Road 222, Lanzhou, P.R.China Tel: +86-931-8912025 Zip Code: 73 URL: oss.lzu.edu.cn Email: [EMAIL PROTECTED], [EMAIL PROTECTED] Tel: +86-931-8912025 Zip Code: 73 URL: oss.lzu.edu.cn Email: [EMAIL PROTECTED], [EMAIL PROTECTED] ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
