AW: [microblaze-uclinux] booting uClinux from FLASH
Hi anand,
Please check out
http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/Documentation/index.html
There is a section
Putting the uClinux image into Flash
http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/Documentation/image_into_flash.html
I think this will help you a lot :-)
For more functionality check out u-boot.
Regards
Jan

> Hi all

>
> We have a memec spartan 2E (microblaze) board running
> uClinux which is directly connected now to the LAN hub with
> its own internal IP address.Till now,we were using XMD each
> time to download the image on to the SDRAM and then boot from
> there.But now we want to use FLASH to boot our image. (I mean
> FLASH to store the image,and move it to SDRAM to execute it)
>
> We have 8MB of FLASH on the P160 extension module(1MB SRAM
> also).I have some doubts regarding FLASH :
>
> 1. How do we program the FLASH chip on the board?Are there
> any tools by which we can directly download the image onto
> the FLASH?If yes,then which image will we download,image.bin
> or image.elf??
>
> 2. Microblaze as such is designed to start executing from
> physical address 0x00000000 on reset.This is mapped to the
> internal BRAM.So is this where our bootloader should reside?
>
> 3. What exactly should the bootloader do?I mean,will the
> bootloader assume that there is an image already existing in
> the FLASH so that it can just issue instructions to move the
> image from FLASH to RAM and then start executing it?
>
> Otherwise,will the bootloader also burn the image on to the
> FLASH and then subsequently move it to RAM?
>
> I am not very sure about this.Can anybody help me with this?

> Now that we have a fully functional ethernet connection on

> program/update the FLASH?

> I have checked the mailing list posts on the website for any
