EABI
Is it possible to compile a Linux application using an EABI compiler (specfically, Xilinx's EDK powerpc-eabi-gcc.exe)? The issue at hand is that we'd like for our customers to be able to use the Xilinx EDK toolchain (which we know they will have) to compile Linx apps without having to install another toolchain (crosstool, ELDK, etc). So, what I'm hoping is that the EDK toolchain can be configured to be Linux compatible binaries, or that there is some kind of wrapper that will handle the incompatible interfaces. Searching around, I've seen some mention of Linux EABI compatibility (for Debian ARM releases), but I haven't found any clear concensus... P.S. My apologies if this message appears on the mailing list twice... -- Brian Silverman Concept X, LLC ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded

Re: ppc-linux still not booting on my virtexII board
Hi , guys , i meet the same problem as yours . when it into the early_init(), the system was hang up . I see your solution , but i don't known it clearly . Can you tell me detailly ??? Why it happened and the solution . Waiting for your reply , thank you :) Hi, * (...)arch/ppc/boot/simple/embed_config.c * Oops, I skipped that code because my bootloader executes the uncompressed kernel image (loaded at 0x) without doing that stuff in the first place.

bringing up latest kernel on EP8248E problems....
Hi geeks,
i am trying to bring up the latest kernel on EP8248 target,
i am using U-boot-1.3.2 and linux-2.6.25-rc8,
I had some problems 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) */
and also added the below lines to the file include/configs/ep8248.h by
looking into the corresponding .dts file in the kernel source
/* pass open firmware flat tree */
#define CONFIG_OF_LIBFDT1
#define CONFIG_OF_BOARD_SETUP 1
#define OF_CPU PowerPC,[EMAIL PROTECTED]
#define OF_SOC [EMAIL PROTECTED]
#define OF_TBCLK(bd-bi_busfreq / 4)
#define OF_STDOUT_PATH /[EMAIL PROTECTED]/[EMAIL PROTECTED]
Now afte doing the above 2 alterations i was able to build the u-boot-1.3.2
source for ep8248e
then i created the uImage with the latest kernel source linux-2.6.25-rc8 and
put that uImage to the target...also i created the ep8248e.dtb from the dtc
(DEVICE TREE COMPILER) and put that to the target and passed this as an
argument to the bootm
I also cross checked in the U-boot environment for the fdt command ... it
was present
Finally when it hanged I started debugging using BDI2000.which helped me to
know atleast what is going wrong, i have added some printk's in the kernel
source but still i am not able to find where and what exactly is going
wrong, The first statement it is printing in the log buffer is
Using Embedded Planet EP8248E machine description and thats it the next
message is
Unable to handle kernel paging request for data at address 0xbfff
Faulting instruction address:0xc0012070 (This nearest address to this
address in System.map file is cacheable_memzero)
and tracing like this i came to know that in the file
arch/powerpc/mm/ppc_mmu_32.c , here in the function __init MMU_init_hw() and
in the line n_hpteg = total_memory / (PAGE_SIZE * 8); probably it is getting
problem because when i tried to print the variable total_memory it is
printing zero !!! :( :( so probably i am thinking it is not able to find
some memory for Hash table :(
Please share your knowledge and skills to solve this problem..
thanks... :)
