Hi,

I am working on the creation of MicroBlaze. I am able to generate singleBRAM of 64 KB. I would like to have many BRAM (say 4) each of size 8KBconnected to the LMB Bus of the MicroBlaze. Can anyone explain how to dothis.

Thanks
Vivek

Hi,

You can add as many LMB_BRAM controllers on the LMB Bus as you like.

I did exactly that and it worked fine from a XPS point of view, but
the SW guys working in EDK claimed that here was some kind of problem
to use the extra RAM. I was a bit surprised since it was a simple task
to make it appear in the address map as a continuation of the original
RAM, maybe you G=F6ran can explain to me what could be the problem? The
guy is on vacation right now and I never had time to get the full
story.

Thanks!

Hi Lars,

I'm not aware of any SW issues on the extra RAM.
The only thing I can think of is the linker script, they just have to
make sure that the new RAM is included in the linker script.
