[microblaze-uclinux] PetaLinux/U-Boot on Suzaku?

[Philipp Hachtmann <hachti@xxxxxxxxx>]

Hi again,

thanks for the follow-ups to my last posting, they were very helpful!

I am sitting here with my Spartan-3e Board and experimenting with 
PetaLinux. I am very happy with that.
Now it comes to the point that I have to do a little project (writing a 
few simple device drivers for absurd hardware) for my university (I 
already use their EDK remotely *g*).
The software should run on a Suzaku SZ130 in the end.

The Suzaku has only a SPI flash used to store the FPGA bitstream and a 
SMSC LAN9115 ethernet chip (not just a PHY!!).

The bootloader combination supplied with the board is something called 
BBoot and as second stage loader "The Hermit". BBoot accepts S-record 
data, but seems not to work. With FS-Boot I have no problems loading and 
starting SW. But FS-Boot does not work with SPI flash.

I could imagine using/modifying BBoot for my purposes.

But what about U-Boot? I tried to compile in the LAN91111 driver (sounds 
similar to LAN9115), but it did simply not work...

Can U-Boot handle the SPI flash on microblaze?

For now, if I want to test an image on the Suzaku, I have to:
- program (RAM) a custom bit file containing FS-Boot instead of BBoot
- serially load a stripped-down U-Boot
- upload my Kernel/Rootfs image via yModem

....that takes LONG... :-(

Any experience? Suggestions?


Best wishes,

Philipp :-)
