What is a .UIMAGE file?
A uImage is a kernel image wrapped for the U-Boot bootloader, common on embedded Linux.
- Did you know
- U-Boot is the bootloader behind most embedded Linux devices.
- A uImage is a kernel image with a 64-byte mkimage header added, recording target architecture, OS, compression method, entry point and checksums.
- U-Boot’s newer Flattened Image Tree format is gradually replacing the legacy uImage, bundling kernel, device tree and ramdisk with stronger integrity checks.
- What Analyser reads
- Inspect virtual-machine descriptors (VMware .vmx, VirtualBox .vbox, OVF/OVA), disc images (Nero .nrg, Alcohol .mds/.mdf, CloneCD), embedded firmware (Intel HEX, Motorola S-record, UF2, ELF/AXF, Device Tree Blobs, U-Boot uImage), partition tables (MBR/GPT with GUIDs), Linux filesystem superblocks (ext2/3/4, SquashFS, cramfs, romfs) and Windows imaging (WIM/ESD) - reading headers directly, no upload.
- Depth of analysis
- .UIMAGE 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 .UIMAGE file
- Drag a .UIMAGE 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.
