Why is ubi layout volume not found in Linux stack?
They ask me to put the DTB, the kernel, the root filesystem and a data filesystem in a UBI image to be written to the flash but I cannot access the UBI partitions once I flashed it (the access fails with error code 22, or -22 in an embedded Linux environment).
Why does Ubi fail to mount on Witherspoon?
When attempting to boot a witherspoon system with dev-5.8, the UBI filesystem fails to mount. [ 3.404365] ubi0: scanning is finished [ 3.408365] ubi0 error: ubi_read_volume_table: the layout volume was not found However, on a Witherspoon that was running op940.00-16 (Linux 5.3.1-7e560ad) I saw the following:
Why is ubi partition not found in U-Boot?
They ask me to put the DTB, the kernel, the root filesystem and a data filesystem in a UBI image to be written to the flash but I cannot access the UBI partitions once I flashed it (the access fails with error code 22, or -22 in an embedded Linux environment). In U-Boot, the partitions are defined by mtdparts:
What to do when flashing an ubi image?
When erasing and flashing the UBI images, you should use partition names instead of offsets. This will clarify things and reduce the risks of errors. You should group the dtb, kernel, rootfs and datafs partitions into a single MTD partition called “ubi”, which you will use to flash the UBI image and then to attach UBI.
How can I change a single file from an ubi image?
Mount it with mount 8.) Make the changes. 9.) Create UBIFS with mkfs.ubifs 10.) Create UBI image with ubinize XXXX = Parameter that is specific to the NAND flash chip used. Thanks for contributing an answer to Unix & Linux Stack Exchange!
How big is the PEB of the UBI image?
The UBI image was created with ubinize and the following configuration: and this command (the sama5-ubinize.cfg is the above configuration) The PEB is indeed 128KB ( 0x2000) and the page size is 2048B ( 0x800 ).
