Fmtsysrom -

If you wanted to create a unified fmtsysrom script for Linux-based embedded systems, here is a basic skeleton.

Since fmtsysrom does not exist natively, here are real commands that perform analogous tasks on different platforms. fmtsysrom

fmtsysrom -v /dev/sysrom prom_image.bin

Compares current PROM content with a binary image. If you wanted to create a unified fmtsysrom

If you were to design fmtsysrom, it would logically handle: Compares current PROM content with a binary image

| Operation | Description | |-----------|-------------| | Probe ROM device | Detect /dev/mtd0, /dev/rom0, or physical EPROM programmer. | | Erase ROM blocks | Send erase commands to NOR/NAND flash (e.g., flash_erase). | | Create filesystem | Write a ROM-friendly FS (SquashFS, CramFS, FFS, or raw binary). | | Install system image | Copy kernel + initrd + rootfs into the ROM region. | | Set boot flags | Mark partition as bootable in bootloader config (U-Boot, GRUB). |
