UBI tests reside in the mtd-utils repository. http://git.infradead.org/?p=mtd-utils.git;a=tree;f=tests/ubi-tests;h=20fd6a043eeb96a81736dd07885f74e4e0bb0cc0;hb=HEAD Maybe you can provide a small shell script which configures qemu? It doesn't have to be fancy, just something David or I can use as staring point. Thanks, //richard
