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:

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 <edk_project_path> (xparameters.h , drivers ) to the <linux_path> ? (I copied only the xilinx.dts file)

Saadia,

I'm guessing that the kernel does not have the right clock information in your device tree. The quick fix is to fix the clock-frequency attribute on the uart. The kernel needs this in order to set the register values in the uart correctly.

This information would be populated automatically, if you used a somewhat recent version of EDK ( >=3D 10.1 ) and add a CLOCK_FREQUENCY attribute on the external clock pin in the mhs file.

I'm actually somewhat surprised you see any output on the serial port at all.

Steve

In reply to saadia

Hi all,

After booting successfully the kernel without a root file system.

I installed a file system on the flash disk. I used: BusyBox 1.12.1, and the script mkrootfs.sh (written by=20

Wofgang Klingauf) to generate the rfs.

=20

I changed the boot arg in the kernel configuration as follows:

[*] Default bootloader kernel arguments =

=20

=E2=94=82 =E2=94=82=20
=E2=94=82 =E2=94=82 (console=3DttyUL=
0,9600
root=3D/dev/xsysace/disc0/xsa3 rw) Initial kernel command string=20

=20

Then I rebooted the kernel, and there were those errors :( :

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:

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.=20

Quoted 8 lines

Then selected 'OS and Libraries' on the left, and entered the values for 'console device' and 'bootargs' (respectively=20 'RS232_Uart_1' and 'console=3DttyS0,9600 root=3D/dev/xsysace/disc0/part3 ip=3Don' ).
Then I generated libraries and BSP, in the edk_project directory and not in the linux src directory.
There were those warnings:

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 <edk_project_path> (xparameters.=

Hi all,
After booting successfully the kernel without a root file system.
I installed a file system on the flash disk. I used: BusyBox 1.12.1, and the script mkrootfs.sh (written by
Wofgang Klingauf) to generate the rfs.

Looks like you don't have the ext3 driver compiled into your kernel.
