Hi We have a working system with xeno 2.6.4, Kernel 3.14.17 and a Kontron PC TT-Module.
It is a normal situation: a Pci card with an fpga spends memory and the kernel driver create the shared mem with rt_crate_heap. The userspace program get the memory with rt_bind_heap. This works fine. Now I change only the cpu from TT-Module to a Bytrail-Modul, and now I get the error that the named heap was not found? "rt_heap_bind(shmName=SLINK4) failed. Error=-11" The kernel says: []sd3:826 map pfn expected mapping type uncached-minus for [mem 0x00050000-0x0005afff], got write-back I found out, when I add "nopat" to the kernel cmd line, the rt_heap_bind function are lucky. But I think this is not the best solution, probably I allocate the memory with wrong flags? Any ideas what must I do? With best regards, Alexander Hänel-Baas _______________________________________________ Xenomai mailing list Xenomai@xenomai.org http://www.xenomai.org/mailman/listinfo/xenomai
