Jan, Stefan, I've tried indeed but with no luck: (qemu) info block ide0-hd0: type=hd removable=0 file=vimage.dat ro=0 drv=raw encrypted=0 mtd0: type=hd removable=0 file=firmware.bin ro=0 drv=raw encrypted=0 floppy0: type=floppy removable=1 locked=0 [not inserted] sd0: type=floppy removable=1 locked=0 [not inserted]
but same time: ~ # cat /dev/mtd0 cat: /dev/mtd0: No such device ~ # cat /dev/mtdblock0 cat: /dev/mtdblock0: No such device or address Guest /dev/mtd0 is character device but QEMU thinks mtd0 is block. My hardware is a network module (like NME-CUE, NME-APPRE, NME-WAE) for Cisco ISR routers: 1GHz Celeron CPU, CompactFlash disk, 1Gb DRAM, 1 FastEthernet, ... Flash memory chip is STM M50FW080 8Mbit NVRAM.

You also need to wire up that flash device on board init, i.e. add some pflash_*_register to pc_init1. Check some embedded board for the precise pattern. Jan
