Hi,
I have downloaded the latest linux kernel linux-2.6-xlnx.git from
http://git.xilinx.com/ .
Than I have downloaded the device tree generator device-tree.git from the
same site.
I launched edk 8.2.02, I designed a system with two powerpc cores:
ppc_405_0, ppc_405_1, and opb bus , a plb bus, and the following devices
with their memory map:
BASE HIGH MODULE
0x00000000 0x0FFFFFFF DDR_256MB_32MX64_rank1_row13_col10_cl2_5
0x40600000 0x4060FFFF RS232_Uart_1
0x40C00000 0x40C0FFFF Ethernet_MAC
0x41200000 0x4120FFFF opb_intc_0
0x41800000 0x4180FFFF SysACE_CompactFlash
I generated the bitsteam system.bit.
After getting the device tree generator from
git://git.xilinx.com/device-tree.git, I have copied the 'bsp' directory and
contents so that it can be used by edk XPS. Then I selected 'device-tree' in
the pull down menu labeled 'OS' in the Software Platform Settings dialog
box.
Then selected 'OS and Libraries' on the left, and entered the values for
'console device' and 'bootargs' (respectively
'RS232_Uart_1' and 'console=ttyS0,9600 root=/dev/xsysace/disc0/part3 ip=on'
).
Then I generated libraries and BSP, in the edk_project directory and not in
the linux src directory.
There were those warnings:

I obtained a binary zImage file (and not zImage.elf) !!!! and I obtained

I copied the system3.ace (3 because it was the third kernel that I tested
:((( ) to the flash disk partition 1 (Type = FAT16, Size = 32Mo ).
And I booted the kernel.
I got fllowing message on the Terminal:

My Questions are:
1. Why he stops here?
2. Why I didn't obtained zImage.elf but simpleImage.virtex405-ml405.elf
3. Do I have to copy other files from my (xparameters.h , drivers ) to the
? (I copied only the xilinx.dts file)
Thanks
