Re: [microblaze-uclinux] uClinux problem

Hi there,


U-Boot> protect off $(bootstart) + $(bootsize)
Usage:
protect - enable or disable FLASH write protection

U-Boot> erase $(bootstart) + $(bootsize)
Usage:
erase   - erase FLASH memory

U-Boot> cp.b $(fileaddr) $(bootstart) $(filesize)
Usage:
cp      - memory copy
The reason why there is no u-boot image in FLASH is because the FLASH unlock, erase and program commands did not complete successfully.
This is probably because you have not set up the u-boot environment correctly. Hence $(bootstart) evaluates to nothing.
A better start would be to follow the Working with Pre-built Design (follow the link below). 

http://developer.petalogix.com/wiki/BoardGuides/Generic/prebuilt
This tutorial run you through the entire board bring up process. Refer to the Automated Board Bring-up section for references to what you are trying to do. 

Let us know you go.

Cheers,
Benny

Hi, it is the first time I use this list. So I hope that somebody could
help me. Sorry if we have sent messages in other emails.

I work in a project with other person and we are trying to put petalinux
in a Spartan 3e with the Petalogix tutorial. We have followed every step
in http://developer.petalogix.com but at finally when we reboot the board
there is no image loaded in the FLASH.

We don't know if there is some problem, or another method to download the
uclinux. We have probed to use XMD and download image.bin in DDR but it
keeps in a loop.

The output is:

FS-BOOT First Stage Bootloader (c) 2006 PetaLogix

=================================================
FS-BOOT: System initialisation completed.
FS-BOOT: No existing image in FLASH.      <----------- I receive this when
I reboot the board.

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




The command line is the next:
