[U-Boot-Users] problem to load uImage but not zImage (on virtex-4board)

[Leonid]

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.

Subject: [U-Boot-Users] problem to load uImage but not zImage (on
virtex-4board)


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.
