[Newbie] Microblaze and uC/OS-II on Spartan3

Hi,

You can't get a 21kbyte program into a 16kbyte memory. The memory blocks in EDK can only have the size of 2**N so you need two memory blocks, one of 16kbyte and one of 8 kbyte. This should give you enough memory.

But I would suggest that you starting to use the external memory on the board.

On the problem with debugging, much more information is needed about your system. Have you enabled HW debug logic on MicroBlaze?

Hi

It's very odd and frustrating, if i start with the port on memec,

have to change the IDCODE in a .bsd fil

/xygdrive/c/DOCUME~1/GAILLI~1/LOCALS~1/Temp/ccvN6OEm.s: Assemble

messages /xygdrive/c/DOCUME~1/GAILLI~1/LOCALS~1/Temp/ccvN6OEm.s:339: Error Variable is accessed using small data read write anchor, but it i not in the small data read write sectio

Any suggestions

Thank you Mr. Bilski

two memory

The .elf can reside in bram and my project is "marked to initialis

BRAMs"

the board

With SRAM or only BRAMs, i have the same problem concerning th

debugging

"Unable to Stop MicroBlaz

Verify if FPGA is configured and MicroBlaze System Clock is connecte properl Unable to connect to MicroBlaze

your system

I don't know exactly what does "HW debug logic enabling" mean, but

have a debug_module connected to microblaze. Concerning my syste with brams, here is my .mhs
