Has anyone every made a PCIe video card work with the AMCC 460EX. I am not sure how to set VIDEO_IO_OFFSET. I have an ATI FireMV 2250 PCIe x1 video card I am trying to get it working with the AMCC 460EX processor. I have u-boot v2009.03. I tried following what the sequoia does for a PCI video card
I changed the board/amcc/canyonlands/config.mk so that TEXT_BASE is 0xFFF80000 instead of 0xFFFA0000 I then added #ifdef CONFIG_VIDEO #define CONFIG_BIOSEMU /* x86 bios emulator for vga bios */ #define CONFIG_ATI_RADEON_FB /* use radeon framebuffer driver */ #define VIDEO_IO_OFFSET 0xe8000000 // <------------- Not sure what this should be #define CONFIG_SYS_ISA_IO_BASE_ADDRESS VIDEO_IO_OFFSET #define CONFIG_VIDEO_SW_CURSOR #define CONFIG_VIDEO_LOGO #define CONFIG_CFB_CONSOLE #define CONFIG_SPLASH_SCREEN #define CONFIG_VGA_AS_SINGLE_DEVICE #define CONFIG_CMD_BMP #endif And I can see the libatibiosemu.a is linked in. However, I cannot see anything on a monitor. ********************************************************** Outbound scan for Spam or Virus by Barracuda at Delta Tau **********************************************************
