Hi Wolfgang, > > Nobody ? > > Well,you're supposed to do some basic code reading yourself.
Of course. It's always the idea to post a question after reading for some time. It either means I don't understand the code, the code really doesn't work or I did miss the most important part in the documents. I guess the answer will follow once the issue is solved. To be specific, I work with the u-boot-usb at91-cdc branch code. I'm not sure if that is all working code at this moment but sounded like the best starting point for my USB code. > > req->buf = (u8 *) NetRxPackets[0]; > > > > This is returning an non existing buffer for some reason and I know not > > much about the ethernet layer to fix this. > > But you know how to use the search function in your favorite editor, > and tools like for example ctags or grep? > > Hint: have a look at "net/net.c". I found that, but it doesn't make sense to me. I'll read it again and hopefully it makes sense to me than. Anyway, my knowledge of the ethernet part in u-boot is limited and I do not focus on ethernet. I will not use ether.c in the end anyway and I was just hoping it would work as a basis to test my new controller code. > And note: as NetRxPackets[] is a static array I can't see how > NetRxPackets[0] should be a "non existing buffer". Well, I guess the point where that's done doesn't show up nicely with grep. I probably missed it and will start to read the ethernet code. I know little of the ethernet code so I feel that as of tomorrow I will skip ether.c and move on to implementing another driver for testing my controller code. My feeling is that I miss something very simple, but I can be looking for it for days. Perhaps I missed some define or whatever, but I'm almost certain that I missed something extremely simple that causes NetRxPackets to be empty somehow. regards, Marcel _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
