Re: [microblaze-uclinux] Booting design from flash then FS-Boot, U-Boot, Kernel

Hi Deepak,

I uploaded the Microblaze design and the uboot and Petalinux images
for the Spartan 3A Starter Kit to

http://www.xlerb.de/transfer/Spartan3AStarterKit-MicroblazeDesign.zip

and

http://www.xlerb.de/transfer/Spartan3AStarterKit-Petalinux-0.30-rc1.zip

I'll keep them online for a couple of days.
You can try loading these into your board in order to verify that your board 
is fine and your serial line is configured correctly.

Next would be to create design and kernel by yourself....

Regards,
		Ulrich

Hi Ulrich,
Thanks once again. I will already do dos2unix for Kconfig file 
which I copy .
Is it possible to you just send me the code which you run for Spartum 3A 

Thanks
Deepak

Hi Deepak,



Hi Ulrich,
         Thanks for giving input. But I have one problem. I build

hardware

project for Spartum 3A on window machine with os option as petalinux.

After

building hardware I pick Kconfig file from there and copy manually on
Spartum3E500_REVC platform code.

After all this I build my kernel as steps mention in you document.

Is these step ok ?
yes, Just one small fix. You should do dos2unix conversion for removing 
CR-LF
line ending.

Regards,
Michal


Thanks
Deepak

Hi Deepak,
	good to know, that you try to do the same thing :-)

I currently do not work with XMD, but given my problem I probably
will :-)

I currently use the petalinux-v0.30-rc1 - file from the web page.

I very closely followed the description in

http://developer.petalogix.com/wiki/BoardGuides/Custom/Tutorial
I ran petalinux-new-platform - Script, to create a new hardware platform directory for the Xilinx Spartan 3A Starter Kit Rev D board that I have 
and for a Linux 2.6 kernel.

Then I also built a specific Microblaze design for the Spartan 3A
Start Kit with UARTLite, parallel Flash support and EthernetLite
using the BSB (Base System Builder) and I included FS-Boot
in BRAM in this design. So, when I download the bitstream of
this design it runs FS-Boot and shows its messages on the serial
console. As the Spartan 3A starter kit has a smaller FPGA, I hat to
reduce the cache size from 8K as proposed in the tutorial to 2K
(for both ICache and DCache).

To build Petalinux (and U-Boot)  I first ran the script
peta-linux-autoconfig and then went through all the options that
are mentioned in the tutorial. The 2.6 Kernel options are
at different places than described in the tutorial, so you have to
do some searching....
"make all" then creates a kernel/filesystem-image and u-boot.

To boot Petalinux, I download the bitstream, this starts FS-Boot
as it is part of the design.

At the SREC-prompt I upload the file u-boot.srec.
This then boots into u-boot.

Now I flashed u-boot and the image similar to the procedure
described in the tutorial:

I loaded the U-Boot configuration:
U-Boot> loadb $(clobstart)
I upload ub.config.img using Kermit protocol.
U-Boot> autoscr $(clobstart)

Then the U-Boot-Image:
U-Boot> loadb $(clobstart)
upload uboot-s.bin using Kermit protocol
U-Boot> protect off $(bootstart) +$(bootsize)
U-Boot> erase $(bootstart) +$(bootsize)
U-Boot> cp.b $(clobstart) $(bootstart) $(bootsize)
U-Boot> protect on $(bootstart) +$(bootsize)

At this time I can download the bitstream and the system
boots into u-boot.

I flash the kernel image. I also used serial upload as I
did not want to mess around with ethernet and tftp at that time.
Be warned however that the kernel upload via serial line takes
about 25 minutes.

U-Boot> loadb $(clobstart)
upload image.ub using Kermit protocol  (wait 25 min)
U-Boot> protect off $(kernstart) +$(kernsize)
U-Boot> erase $(kernstart) +$(kernsize)
U-Boot> cp.b $(clobstart) $(kernstart) $(kernsize)
U-Boot> protect on $(kernstart) +$(kernsize)

At this time I can download the bitstream and the system
boots into u-boot and then boots the Petalinux kernel
as described in my previous post.

However putting the design in SPI flash, let the FPGA
configure from there  and boot linux does not work for me
in the moment. I guess I have to learn a bit of XMD to do
the low level debugging...

Regards,
		Ulrich

BTW: Do you have the Base System Builder running under Linux?
I have CentOS here but BSB refuses to start;

ERROR:MDT  - Unable to run BsbWiz!

So - currently I use BSB under Windows and copy files :-(

Hi Ulrich,
I am also try to port Petalinux on Spartan 3A Starter Kit .But 
unable to find any linux prints on terminal  except FS_Boot prints.
Can you
tell me the steps which you follows.

I am following these steps

1.Take spartum 3E-500 REVC linux kernel code.

2.Generate Kconfig for Spartum 3A board.

3.Copy this Kconfig in spartum 3E-500 REVC code.

4.Build Kernel.

5.Boot FS boot from RAM.

6.Copy kernel image(image.bin) in ram start address by using dow
command.

7.Con at start address.

Thanks
Deepak

U-Boot, Kernel

Hi,
	I'm about to port Petalinux to the Spartan 3A Starter Kit (Rev D)
Board.

I followed the Petalinux documentation closely and created a
Microblaze design with
fs-boot and also flashed u-boot and the kernel image fine. I can now
boot
Petalinux when I freshly download the Microblaze design via the JTAG
interface (USB-Cable).

What I would like to have is a Microblaze configuration that loads
into the
FPGA from SPI flash at reset time.

I used IMPACT to put the bitstream in the ATMEL AT45DB161D serial
flash. On reset it indeeds downloads Microblaze and fs-boot so that I 
can
see its boot message:

=================================================

=================================================
FS-BOOT: System initialisation completed.
FS-BOOT: Booting from FLASH. Press 's' for image download.
FS-BOOT: Booting image...

then nothing happens.

If I interrupt the boot process and press 's'. I can download
the u-boot.srec-file, but this hangs as soon as u-boot is trying to
display the flash statistics and then resets strangely into fs-boot
again:

Maybe the parallel flash is not available when loading the

Any hints are very welcome.
