How to retrieve data from an extracted Ubi image?
I dumped a NAND flash a while ago and analyzed the dump with binwalk . Binwalk could find a SQUASHFS filesystem but unfortunately it was not possible to retrieve the data because it is monted on top of UBI and neither unsquashfs utility nor sasquatch could do something.
How to use Red Hat Universal base images ( UBI )?
Using Red Hat Universal Base Images (UBI) offers a way to build your container images on a foundation of Red Hat Enterprise Linux software. See Using Red Hat Universal Base Images for details on using Red Hat UBI container images.
What’s the difference between Ubi file and UBIFS?
UBI file is an UBI Filesystem Image. UBI stands for “Unsorted Block Images”. UBIFS is a flash file system, which means it is designed to work with flash devices.
Is the UBI base image freely redistributable under the EULA?
The UBI base image is freely redistributable under the UBI EULA. Non-UBI refers to packages that are not governed with the UBI EULA. 7. What is the difference between the pre-UBI base images and UBI base images?
Which is file system works on top of UBI volumes?
UBIFS file system, which works on top of UBI volumes. Here is a list of some of UBIFS features:
What does UBIFS mean in terms of compression?
Compression. UBIFS supports on-the-fly compression, which means it compresses data before writing them to the flash media, and decompresses before reading them, and this is absolutely transparent to the users. UBIFS compresses only regular files data. Directories, device nodes and so on are not compressed.
How are Ubi and UBIFS tolerant to power failures?
Both UBI (see here) and UBIFS are tolerant to power-cuts, and they were designed with this property in mind. UBIFS has internal debugging infrastructure to emulate power failures and the authors used it for extensive testing. It was tested for long time with power-fail emulation.
