[microblaze-uclinux] Boot Problems at Virtex2Pro

[alcofa04@xxxxxxxxxxxxxxx]

Hi!

I know exists a post that speaks about this subject, but I don't
understand how solve it.

I'm a new user of Xilinx board and I want to load petalinux on this board.
My board is Xilinx Virtex2Pro, and it hasn't a flash, so I want to load on
SDRAM.
When I am creating the hardware platform, I disable "cache setup" and
select Microblaze proccessor.
Memory base address is 0xA0000000.

I tested the memory and the results are:

-- Entering main() --
Running 32-bit test...PASSED!
Running 16-bit test...PASSED!
Running 8-bit test...PASSED!
-- Exiting main() --

I tried download petalinux:

xmd
XMD% connect mb mdm -cable type xilinx_platformusb port usb21
XMD% dow -data images/image.bin 0xA0000000
XMD% rst
XMD% con 0xA0000000

On console, I can see nothing.


Other way I tried:

Adding fs-boot at hardware platform.
Download bitstream via: impact -batch etc/download.cmd
On kermit:

-- Why it do this?

I tried too:

=================================================
FS-BOOT First Stage Bootloader (c) 2006 PetaLogix
Project name: XUP-V2Pro
Build date: Sep 12 2009 12:32:13  S

FS-BOOT: Waiting for SREC image....

$ cat images/image.srec > /dev/ttyUSB0

FS-BOOT: Image download successful.
FS-BOOT: Warning image location differ from default boot location. Image
will not boot automatically after POR.
FS-BOOT: Press 'n' to boot old image.
FS-BOOT: Use new image.
FS-BOOT: Booting image...

And the system freeze here.

What is wrong?

Thanks!!
