ubi_wl_init() is called by ubi_attach(). So, as soon your UBI image is attached the WL subsystem is fully initialized and ready to use. If you try to use it before you're in undefined state. u-boot must not run the erase_worker() before the attach phase is done. Do you have more details what exactly happened? This needs a deeper investigation. Thanks, //richard _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
