USB Display firmware + U-disk parser
This page parses combined .bin images used in MacroSilicon USB display demos and production flows (for example MS9133_DEMO_V1.1.4_*_add_udisk_*.bin):
- Leading section: chip firmware, downloadable as
fw.bin - Trailing section: FAT filesystem starting at the MS-DOS boot sector—list each file, download individually, or fetch a
.zipof all files

Scope & disclaimer
Scope: MacroSilicon USB display / casting firmware images that bundle firmware with a U-disk FAT partition.
Unofficial: Provided by the UltraSemi project site—not a MacroSilicon OEM tool; no vendor endorsement.
No warranty: No guarantee of offset detection, FAT parsing, or exported file correctness.
Your risk: You accept responsibility for burn failures, corrupted assets, or wrong design decisions; validate on target hardware before production.
Local only: All processing runs in the browser; files are not uploaded.
| Capability | Description |
|---|---|
| Firmware split | Locates the FAT boot sector and exports preceding bytes as fw.bin |
| FAT parse | Common FAT16 / FAT32 layouts with subdirectory recursion |
| Per-file download | Download any file from the table |
| Zip bundle | {original-name}_udisk_files.zip containing all U-disk files (store, no compression) |
| MD5 | Full image, firmware segment, and per-file MD5 for verification and archiving |
Steps
- Drop or select a combined
.bin(e.g.MS9133_DEMO_V1.1.4_20260331_add_udisk_20260331.bin). - Review firmware size, FAT offset, image/firmware MD5, and the file list.
- Click Download fw.bin for the firmware-only image.
- Download files individually or use Download all files (.zip).
Limits
- Detection: Scans 512-byte aligned offsets for a valid FAT boot sector (
0x55 0xAA); prefers candidates whose directory can be walked. - Not supported: MBR multi-partition layouts, exFAT, encrypted or custom non-FAT payloads may fail.
- Long names: FAT LFN entries are supported; verify unusual 8.3 names with a hex editor if needed.
