Thanks for the reply scott, :)
i forgot to mention , yes i am using device tree aware u-boot but the problem is when i tried to build the u-boot source ( first i did ""make ep8248_config"" and then ""make"") it was giving undefined reference related to ft_board_setup() function so i altered the U-boot-1.3.2 source code... i added the below code to the following file board/ep8248/ep8248.c
#if defined(CONFIG_OF_LIBFDT) && defined(CONFIG_OF_BOARD_SETUP) void ft_board_setup(void *blob, bd_t *bd) { ft_cpu_setup(blob, bd); } #endif /* defined(CONFIG_OF_LIBFDT) && defined(CONFIG_OF_BOARD_SETUP) */
The 8260 ft_cpu_setup() seems a bit deficient -- most pertinently, it's not calling fdt_fixup_memory(), but it's also missing brg frequency setup and maybe some other things. Look at other_cpu_setup() functions (e.g. 8xx, 83xx, 85xx) for an example of what to do.
#define OF_CPU "PowerPC,8248@0" #define OF_SOC "soc@f0000000" #define OF_TBCLK (bd->bi_busfreq / 4) #define OF_STDOUT_PATH "/soc@f0000000/serial@11a80"
These hardcoded things shouldn't be needed anymore.
and how to use cuImage.pq2 ?
You'd need to change the makefile to tell it to build that target for this board. I recommend fixing u-boot, though, if you're already inclined to go down that path.
also i dint get what is dtbImage.ep8248e ? is that same to ep8248e.dtb ??
No, that's an image for the PlanetCore bootloader. If you don't have it, you probably built with 'make uImage' rather than 'make zImage'.
