Sorry, I misread the ftp list, I was rather thinking about: http://download.gna.org/adeos/patches/v2.6/powerpc/older/adeos-ipipe-2.6.30.3-powerpc-DENX-2.7-06.patch It resulted on same problem > as reported with Linux 2.6.30.3 I-pipe 2.7-02. > > Was there any particular set of changes that you expected it could fix the > problem? Do you think more recent versions may work? If yes, which version > could be tried? Yes, there was a fix, specifially in the powerpc tree, with mappings issue. But I think it is older than 2.6.32. Now that I look at your message again, your problem seems more likely to be in your code. Specifically, you say: "bus address returned by pci_alloc_consistent()". I do not think pci_alloc_consistent return value is a bus address. The dma_handle returned by pointer probably is. But I am not sure you are supposed to know this. Please post your code (or a minimal, standalone version of it which demonstrates the problem). -- Gilles. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
