EST SBC8260 & abatron

[Gessner, Matt]

A long subject...

I'm having trouble accessing the upper 8MB of the 16MB SDRAM SIMM on this
board.
I'm wondering if I don't have something configured wrong in my BDI2000
config file.

Would anyone care to send me one they're using that works?

Also, we're trying to load the linux kernel into this system.
How are the folks out there doing that?  Via ftp?  Via a bootloader on the
2MB FLASH
chip on the board tied to /CS0?  What exactly?

Thanks for sharing...

Matt

P.S. A reply to the group will suffice, unless you don't want it broadcast.

TIA

Matt

Although I don't have a 8260 here to test, you could send me your BDI2000
config file.

BTW - which firmware version are  you  running?  Abatron  implemented
some Linux-friendly extensions lately...

Is a MPC8xx file of any uise to you?

Well, why don't you use your BDI2000 to load the image, or to load it
and burn it to FLASH? You already have a BDI, so use it...

Didn't we discuss this once before?  There were some suggestions posted.

I am using a high speed serial S-record downloader.  I guess I will
be posting the boot rom and the loader for the EST8260 when I get
a chance later this week.  I then load and flash a kernel the same
way.  I have some flash utilities that run from Linux and just reflash
kernels into different areas for testing.  I have just finished a
program to hack the zImage header so the VxWorks boot rom will load
it.  I only spent about half an hour, so it needs a little cleaning up,
but it seems to work.  I am hoping someone will provide a TFTP loader
for the code I post.......
