  To: u-boot

Hi All,

	I have successfully built u-boot 1.2.0 on my Avnet evaluation 
board (ml403 like) which uses virtex-4 xilinx FPGA with built-in ppc405 
processor. The u-boot was configured to deal with UART lite.

I have build also zImage.elf which runs very well on my board.
I have however difficulties to run kernel image via u-boot.

My board has 32 MB of RAM memory (address range 0x000000 - 0x1ffffff)

The steps which I have done are as following:

1. I have build u-boot and loaded it via jtag to my board
XMD% dow u-boot1a.elf
        section, .text: 0x01a00000-0x01a0d838
        section, .resetvec: 0x01a122f0-0x01a122f4
        section, .rodata: 0x01a0d838-0x01a0fc5b
        section, .reloc: 0x01a0fd00-0x01a102a8
        section, .data: 0x01a102a8-0x01a10740
        section, .data.rel: 0x01a10740-0x01a1076c
        section, .data.rel.local: 0x01a1076c-0x01a10ba4
        section, .u_boot_cmd: 0x01a10ba4-0x01a10db4
        section, .bss: 0x01a10e00-0x01a122f0
Downloaded Program u-boot1a.elf

2. I have loaded the uImage via jtag to the memory location 0x600000

3. I have started u-boot:

U-Boot 1.2.0 (Aug 31 2007 - 10:49:57)
### No HW ID - assuming ML403
DRAM:  32 MB
Using default environment
In:  serial
Out:  serial
Err:  serial

Hit any key to stop autoboot:  0

4. I have started uImage

=> bootm 0x600000
## Booting image at 00600000 ...
Image Name:  Linux-2.6.21-rc6
Image Type:  PowerPC Linux Kernel Image (gzip compressed)
Data Size:  981837 Bytes = 958.8 kB
Load Address: 00a00000
Entry Point:  00a00000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
## Current stack ends at 0x01FCC668 => set upper limit to 0x00800000
No initrd
## Transferring control to Linux (at address 00a00000) ...

5. After that the system just hangs

6. I have tried as well to run zImage.elf from u-boot (zImage.elf runs 
well when started  straight from jtag):

=> bootelf 0x600000
Loading .text @ 0x00400000 (14140 bytes)
Loading .data @ 0x00404000 (987136 bytes)
Clearing .bss @ 0x004f5000 (8504 bytes)
## Starting application at 0x00400000 ...
loaded at:  00400000 004F7138
board data at: 004F5120 004F5138
relocated to:  004040B4 004040CC
zimage at:  00404EA9 004F49F5
avail ram:  004F8000 01FFFFFF
Linux/PPC load: console=ttyUL0,9600 root=/dev/nfs rw nfsroot=129.117.144.113:/opt/eldk41/ppc_4xx,tcp ip=::::virtex4-mirek:eth0:dhcp panic=1 
Uncompressing Linux...

7. After that system just hangs

My observation is that:
- when launching zImage from u-boot, the system blocks during zImage 
  uncompressing
- when launching uImage from u-boot  the system blocks after u-boot 
  uncompresses the uImage

I do not know what I do wrong. Maybe the processor is not set to the 
correct mode of the apportion or the memory locations are not correct.

I do not also know what should be the proper: Load Address and Entry Point 
for uImage. The zImage refers to the location 0x400000 (as listed above).

I attache to this post my Avnet board u-boot configuration.

Any suggestion is welcome

Best Regards

Mirek
