Thank you! Tests done up to now tell Adeos 2.6.35.9-1.16-01 fixes the issue. We applied it to kernel 2.6.35.13. Should we want to try upgrading to kernel 3.0 or later (like in official Blackfin distributions) in future, could you clarify how to patch with Adeos, since the latest official patch in Adeos website for Blackfin is 2.6.35.9-1.16-01? I tried checking your http://git.denx.de/?p=ipipe.git;a=summary but I do not understand if there are patches in there or kernel sources already patched. _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
