This seems to clear up a similar/identical problem we had on our hardware, but haven't had time to investigate. Good work, thanks! I'm attaching a patch against CVS (last synced on the 10:th of December, since the sourceforge server seems to be down as usual - but I don't think that file has been modified) for others testing on other boards/chips, since I only have 1550 hardware here. / Leif -------------- next part -------------- A non-text attachment was scrubbed...
