Subject: [U-Boot] AMCC 460EX Video on PCIe
Date: Tue, 19 May 2009 16:19:22 -0700 [thread overview]
Message-ID: <1242775162.19889.11.camel@lt-linuxhenry> (raw)
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.
