Re: [microblaze-uclinux] Booting uClinux

She boots without much of a problem! Its a good start.  I've based my design on the files Tyrone provided and his kernel image (2.4.27-uc1) works fine.  The issue I'm running into now, however, is that the kernel still hangs at "Freeing init memory" whenever I compile my kernel (2.4.29-uc0).  Thanks to Tyrone, I know my EDK configuration is correct now... is there anything I'm missing?

I've modified the following files to reflect the design:
    drivers/mtd/maps/mbvanilla-flash.c
    include/asm-microblaze/mbvanilla.h
Is there anything else?

Also, does anyone know what the BUS_WIDTH variable in mbvanilla-flash.c represents? Evidently not the data bus width of the flash as I had originally thought.

Thanks,
    Ryan Ahern

Ryan,

You can download my EDK 6.2 project at:
http://www.eee.hku.hk/~tokwok/MB-3s400c.zip

Please kindly note that:
1. My system runs at 40MHz.
2. In the ZIP file, I have included a kernel image (image.bin) for your testing.
3. The flash is only used for downloading the kernel image to RAM, and hence
    I haven't enabled the flash in uClinux yet.

Hope this helps!

Cheers,
Tyrone

Tyrone,

    What did you use to test the flash to ensure proper reading/writing? 

    Would you also mind posting your MHS file? I'd really like to take a
look and see where my Flash settings are off.

    Thanks,
          Ryan

Hi,
    

I am also using the NuHorizons S400 board and using EDK6.2. I
  
would
    
like to ask if
you have enabled the RAM filesystem support in:

Memory
  
Technology Devices (MTD) | Mapping drivers for chip access |
    
Generic uClinux
  
RAM/ROM filesystem support
    

BTW, with reference to David's S1500 design
  
files, I am able to use
    
the flash on that board to download the kernel
  
image. (Thanks David
    
;-)

Cheers,
Tyrone
