[microblaze-uclinux] fs-boot/u-boot trouble on ml403

[abelshaw@xxxxxxxxxx]

Hello all, 

I am trying to put a linux-2.6 kernel onto a ML403 board.

The step I'm stuck on is the FS-BOOT just hangs up while downloading the U-boot
image.
=================================================
FS-BOOT First Stage Bootloader (c) 2006 PetaLogix
=================================================
FS-BOOT: System initialisation completed.
FS-BOOT: No existing image in FLASH.  Starting image download.
FS-BOOT: Waiting for SREC image....
-
The spin wheel goes for a split second, then nothing happens even after the cat
command finishes.

I've checked the u-boot image and the file endings only have just LF endings I
believe (0A endings), so I don't think I have the problem described in the uart
issue in fs-boot thread. (I also checked my serial cable just to be sure and it
works)

Two things that I think could possibly be fouling it up, but I don't know enough
about this kind of project yet to know how to check:

1) To get the kernel to actually build Vendor settings of Xilinx/ML401 had to be
used, as it wouldn't build when we changed it to ML403.  Perhaps the image is wrong?

2) What I think might be messing this up is I had to manually edit the
auto-config.h file because the edk-9.1 I'm using didn't recognize the Flash
memory (of any type) so it didn't create a FLASH_MEMORY_START so the fs-boot
program wouldn't build.  I added in manually the START and SIZE of my Flash
Memory peripheral, could there be memory address issues from changing it that way?

The only two lines I added to the auto-config.h file the edk created were

#define CONFIG_XILINX_FLASH_START (0x41800000)
#define CONFIG_XILINX_FLASH_SIZE (0x00010000)

Let me know if there is also a much easier way that I've missed.

Thanks,
-Alex
