Jon, I think the Lattice web has at least sporadic issues with the download there are several people complaining about the downloads not starting, so I dont it the issue of not being able to uncompress .bz2 Antti

The file you download is a tar.bz2, not zip or exe. You need to extract it with: tar xjf src.tar.bz2 Cheers, Jon

We apologize for the inconvenience.

Webmaster"

this problem? any solution to it?

hm, I guess the LM32_RAM that is included when JTAG debugger is enabled is direct processor connected block RAM. as I had JTAG configured off this module was also out, so I only had wishbone block RAMs left in the system. For the custom instruction support there is anyway an update needed so I guess the access to direct CPU connected on chip memories will also be available then. Antti PS for those who want to play with LatticeMico32 on Xilinx platform I uploaded the ISE project navigator project that I used for testing, its rather minimal LM32 system tested to work in Virtex-4, available @ www.microfpga.com , download area...
