Hi Pedro,
Thanks for your contributions. Last night I upgraded the s/w with the latest sys and fpga. The only thing to watch out is to download the app using zip, otherwise you get an error. Have not have a chance to do any measurement, but the upgrading worked perfectly.
With regards to the FPGA code compiler license how much does that cost? The thing is that for other open source s/w, the tools are also free. Then how would people deal with open source fpga source?
I am not sure if the community is willing to contribute to buy a license, but it is something to think about.
