Hi Patrick,
We're also using the same board on the current project and I need a
reference design to look against when I can't get something to work. I
want to see what it is that I'm doing wrong. I don't know if this is
appropriate to ask, so I'll just come out and ask. Could you send me the
MHS and MSS file you're using?
Thanks,
Loi

Hello ,
I am trying to run the uClinux microblaze kernel on a NuHorizons Spartan 3
board.
So far I can boot the kernel from sdram but I encounter problems probably
due to improper configuration on my part.
The most obvious is that the kernel thinks it has 32 MB of memory to use
when in fact there is only 8 MB sdram.
I attached the boot console output.
Another problem is that I do not get a shell prompt after the boot process.
I also attached my mhs file and .config file
Here are details of the board:
-Spartan 3 XC3S400
-8 MB 16 bit wide sdram
-I am not using the flash ram yet (starting simple)
-One serial port for the console
-One jtag uart (can this be used for debug console? )
-The system currently operates with one clock set at 40 MHZ
-I disabled microblaze caching to start simple
The sdram works fine in memory tests I let run for 48 hours in a simple
microblaze program.
I am not sure where to tell the kernel about memory size. I only modified
the mbvanilla.ld file so far.
Thank You!
Patrick Robin
