Jun 6, 2010

This release is a minor update that fixes bugs and addresses minor performance issues.

Code written for the 2.1.0 release should work unmodified. Bitfiles should be recompiled to ensure that they use the latest version of cpci_bus which fixes an issue where register writes may be missed when performing a series of back-to-back writes.

• Increase DMA performance (bigger buffers to prevent stalls)
• SCONE builds correctly on more systems (removed dependence on /usr/lib/libnet.a)
• Allow rkd to build under Ubuntu 10.04 (issue reported by gcarvajalb on the forums)

• Some register writes were missed when doing back-to-back writes (a buffer full signal was asserted too late)
