[Ltib] EA3250 problem with console display driver (PCIMEM_BASE)

[Miguel Aveiro]

Hi all,

I use a EA3250 board and Fedora 13 as host, running the last CVS ltib - 10.1.1 ($Revision: 1.72 $) -. My goal is to use LCD expansion connector of the board and with a video DAC be able to plug a VGA monitor instead of using the 3.2 inch QVGA TFT color LCD.

When I try to compile the kernel with Console display driver support->VGA text console or Framebuffer console support, I get this error

Build time for kernel-2.6.34-lpc32xx: 119 seconds

Failed building kernel-2.6.34-lpc32xx


The problem is in this function of drivers/video/console/vgacon.c:

vga_vram_base = VGA_MAP_MEM(vga_vram_base, vga_vram_size);

And VGA_MAP_MEM is defined in arch/arm/include/asm/vga.h

#define VGA_MAP_MEM(x,s)    (PCIMEM_BASE + (x))


When I searched the /home/miguel/ltib/rpm/BUILD/linux-2.6.34/arch/arm/mach-lpc32xx/include/mach/platform.h I found this:

#define LPC32XX_LCD_BASE            0x31040000

Does anybody knows if I can use the LPC32XX_LCD_BASE in place of PCIMEM_BASE?? Or anybody have already had this error??


Thanks
Miguel
