The symptom is error messages like -"cannot open /dev/ubi0_0". - -One possible solution of this problem is to pre-create UBI device and volume -nodes. there is even a script which may be used for this in ubi-utils/scripts/. -But this is not enough because udev will still remove and re-create the nodes -and tests will still fail. So you need to stop removing device nodes using -the following udev rule: - - KERNEL=="ubi*_*", ACTION=="remove", OPTIONS+="ignore_device" - -In our Ubuntu distribution we put that to new file: -/etc/udev/rules.d/50-local.rules - -Another possibility is to call udevsettle utility in libubi after the volume -has been created See src/libubi.c - the call is there but is commented out. -This is anyway an ugly hack, but works, although makes the tests slower. |
