What is a .ITB file?
ITB is a U-Boot FIT image bundling a kernel, device tree and more for booting.
- Did you know
- A FIT image lets the U-Boot bootloader carry everything it needs in one file.
- FIT stands for “Flattened Image Tree”, and the file is built with U-Boot’s mkimage tool from a device-tree-style source.
- A single FIT image can bundle several kernel and device-tree pairs as named configurations, letting one image boot different hardware variants.
- What Analyser reads
- Identify and read more disk images, firmware and VM files: TRX router firmware, USB DFU images, UEFI/BIOS flash volumes (.fd/.rom), Linux UBI volumes, Android sparse images (.simg), U-Boot FIT (.itb), raw floppy images (.dsk/.ima/.vfd with FAT boot sector), VMware snapshot metadata and NVRAM, Parallels VMs and disks (.pvm/.hdd), OVF manifests (.mf) and Veeam backups (.vbk).
- Depth of analysis
- .ITB is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .ITB file
- Drag a .ITB file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
