Hi, I noticed that the commit id c087e0804f0290e9886899e8a3cccb07c4ce088b flagged static UBI volumes as DEVFS_IS_CHARACTER_DEV. A consequence of this flag is that commands like: # cp /dev/nand0.ubi_volumes.ubi.my_static_vol file will not work because the cp command will see a src file (the static UBI volume) with a size of -1 (FILE_SIZE_STREAM) and keep on reading from the volume until a flood of "UBI assert failed in ubi_eba_read_leb at 359" asserts comes out of the console. I tried to comment out the flag assignment, just to see what happen: int ubi_volume_cdev_add(struct ubi_device *ubi, struct ubi_volume *vol) { ... cdev->size = vol->used_bytes; // if (vol->vol_type == UBI_STATIC_VOLUME) // cdev->flags = DEVFS_IS_CHARACTER_DEV; cdev->dev = &vol->dev; ... and then the cp command worked than as expected. Could someone shortly confirm that the DEVFS_IS_CHARACTER_DEV flag for static UBI volumes is really needed (to avoid some other problems that my superficial test does not triggers) ? giorgio Giorgio, iw3gtf@xxxxxxxx _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
