Hi All. I am trying to run xenomai on blackfin ADZS-BF537-EZLITE board, but I'm getting an error when trying to execute any test programs like arith, clocktest etc.
Software versions: linux-2.6.35.7 xenomai-2.5.5.2 example: # /usr/xenomai/bin/arith Xenomai: binding failed: Cannot allocate memory. # dmesg | tail -5 [ 7.288690] PHY: 0:01 - Link is Up - 100/Full [ 7.502574] Looking up port of RPC 100005/1 on 192.168.4.9 [ 7.593737] VFS: Mounted root (nfs filesystem) on device 0:11. [ 7.601396] Freeing unused kernel memory: 104k freed [ 300.787988] Xenomai: arith[330] cannot map MAYDAY page All happens in root console. I found that the error returns from the function validate_mmap_request when the flag BDI_CAP_MAP_DIRECT is checked in file->f_mapping->backing_dev_info->capabilities while mapping memory in map_mayday_page. Looks like this flag must be set for /dev/rtheap, but it's not. Is it bug on NOMMU system or maybe my fault? I've build kernel and system as explained in README.INSTALL.
