hi,

I'm trying to port Linux 2.6 on Avnet FX12 MM board with U-Boot and the help
of xilinx ML403 config.

I have generate my costum xparameters.h file with EDK 8.2i.
I use ELDK 4.1 and Linux 2.6.20.x.
I have modified ml403.h u-boot's config file to adapt it for my board and I
have no problem to boot u-boot.
I use the right board_info structure from <asm/ppcboot.h> and not the one in
xilinx_ml403.h.

When I load the zImage directly with xilinx xmd debugger, the kernel start
without problem (if I don't have KGDB or SERIAL_TEXT_DEBUG option in my
kernel config). But when I try to load the uImage with u-boot, the kernel
start but crach befor I can see something on output.
The kernel start because I debug it and the platform_init is ok, setup_arch
too and it crach after ppc4xx_setup_arch at  printk(KERN_INFO "Xilinx ML403
Reference System (Virtex-4 FX)\n") line  when the kernel access in printk.c. 

I use the opb_uart16550 IP in my Xilinx design and the associat drivers in
u-boot and linux.

I'm new in linux embedded and I'm in internship...I have any idea where and
what is the problem, certanly in the serial int I guest but I'm not sure.

Thanks and sorry for my english I'm fench.

I take it you are running PPC405 core, right (since it's possible use
Microblaze there)? Try to uncomment "#define DEBUG" in lib_ppc/board.c.

You'll see u-boot output regarding board info, see whether it's
consistent.

Regarding debug - do you use BDI2000? In any rate, are you sure kernel
crashes on that printk() operation or you just don't see any output on
console? Where exactly it crashes?

Leonid.

What are you passing for the kernel command line?
Can you post your .config?

Cheers,

Grant is right - kernel command line (defined by u-boot variable
"bootargs") is also very important, though it's difficult to see how
wrong command line can crash printk(). It definitely can prevent serial
output from showing up on console though.

Leonid.

First Thanks from your reply...

In my ml403.h u-boot config's file I've got that:
...
#define    CONFIG_EXTRA_ENV_SETTINGS                    \
    "netdev=eth0\0"                            \
    "addip=setenv bootargs $(bootargs) "                \
            "ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask)"    \
        ":$(hostname):$(netdev):off panic=1\0"            \
    "rootpath=/opt/eldk4.1/ppc_4xx\0"                \
    "bootfile=/tftpboot/fx12/boot/uImage\0"                \
    "nfsargs=setenv bootargs nfsroot=$(serverip):$(rootpath)\0"    \
    "net_nfs8=dhcp 800000 $(bootfile);run nfsargs addip;bootm\0"    \
    "net_nfs4=dhcp 400000 $(bootfile);run nfsargs addip;bootm\0"    \
    "net_nfs2=dhcp 200000 $(bootfile);run nfsargs addip;bootm\0"

#define CONFIG_BOOTCOMMAND      "run net_nfs8" /* autoboot command    */
#define CONFIG_BOOTARGS         "console=ttyS0,9600"

#define CONFIG_LOADS_ECHO       1       /* echo on for serial download    */
#define CFG_LOADS_BAUD_CHANGE   1       /* allow baudrate change    */
...

My Linux config is very simple for now, I give you my .config in 
attached file but my commande line is same as u-boot:
CONFIG_CMDLINE_BOOL=y
CONFIG_CMDLINE="console=ttyS0,9600"
I try to turn off this option to be sure u-boot passed the BOOTARGS 
commande to the kernel but no result.

The output of u-boot is:

To debug the kernel I use the xilinx xmd debugger with the JTAG cable 
and GDB but I don't have the BDI2000 debugger.
I make a breakpoint at ppc4xx_setup_arch and then I continue with stepi 
commande. As you could see the printk() is not finish when the kernel crash:

I also try to use the command line specified in 8250_early.c like 
console=uart,mmio,0x40401003,9600n8 (0x40401003 is my 
XPAR_UARTNS550_0_BASEADDR + 3) but no result too.

So if you have any ideas or suggestion...

Thanks,
Guillaume Berthelom

Hi,

I find my problem! it was like you said a problem with the command line 
in u-boot. I had defined  CONFIG_EXTRA_ENV_SETTINGS before 
CONFIG_BOOTARGS, that's it! and you have to do the opposite.

Thanks for your help,
Guillaume Berthelom
