Matt- About Vikram's 10/100 mode question, we were wondering if it's a design flaw; i.e. something wrong from the start in the original opencores.org source, or if it's fixable but hasn't been a high priority item given USRP2's high data rate requirements. But then I found this post:
http://www.ruby-forum.com/topic/143084 So I guess the former. If there are any hints you can give on what's wrong, we can take a look. Maybe our guys can get it working. -Jeff > Thank you for your email. > >> The mac is all contained in simple_gemac, and above that in >> simple_gemac_wrapper: >> http://code.ettus.com/redmine/ettus/projects/fpga/repository/revisions/master/show/usrp2/simple_gemac >> simple_gemac_wrapper in the fifo_2clock_cascade files. >> which is instantiated in u2_core.
