After modifying the gem5/system/alpha/console/Makefile to point to the
crosstool I donwloaded from gem5 website, I executed make all and recompiled
the console. However, the following error occurred when I try to simulate:

I set the mem size at 4 GB in Benchmarks.py. The highest value that does not
cause this error is 2047 MB. Any ideas why this is happening?

ALPHA_FS
You should just be able to compile it and use the compiled version instead of
the one you downloaded from the website.

Is it possible for you to give some more details on how to implemented what you
said there? How should I update gem5/system/alpha/console/console.c so that I
can use more than 2 GB of main memory in my simulations?
