Krzysztof, After working through some Microblaze configuration issues, I am now at a very similar point with mounting ann RFS from a very small uClinux running on a Spartan3 S400 device: Linux version 2.4.27-uc1 (ssanders@debian-rbr) (gcc version 2.95.3-4 Xilinx4 On node 0 totalpages: 256 zone(0): 256 pages. zone(1): 0 pages. zone(2): 0 pages. CPU: MICROBLAZE Console: xmbserial on UARTLite Kernel command line: Calibrating delay loop... 2.45 BogoMIPS Memory: 1MB = 1MB total Memory: 264KB available (536K code, 201K data, 36K init) Dentry cache hash table entries: 512 (order: 0, 4096 bytes) Inode cache hash table entries: 512 (order: 0, 4096 bytes) Mount cache hash table entries: 512 (order: 0, 4096 bytes) Buffer cache hash table entries: 1024 (order: 0, 4096 bytes) Page-cache hash table entries: 1024 (order: 0, 4096 bytes) POSIX conformance testing by UNIFIX Linux NET4.0 for Linux 2.4 Based upon Swansea University Computer Society NET3.039 Initializing RT netlink socket Microblaze UARTlite serial driver version 1.00 ttyS0 at 0xffff2000 (irq = 1) is a Microblaze UARTlite ttyS1 at 0xffff4000 (irq = 2) is a Microblaze UARTlite Starting kswapd xgpio #0 at 0xFFFF5000 mapped to 0xFFFF5000 Xilinx GPIO registered RAMDISK driver initialized: 16 RAM disks of 128K size 1024 blocksize eth0: Xilinx EMAC #0 at 0xC0000000 mapped to 0xC0000000, irq=3 uclinux[mtd]: RAM probe address=0x800b88a8 size=0x597b1000 uclinux[mtd]: root filesystem index=0 Kernel panic: VFS: Unable to mount root fs on 1f:00 . It's what I expect, though, since I only downloaded the text, init, and data sections and the romfs section was MUCH too large for the limited amount of RAM that I have (1MB). I haven't paid any attention yet to the rootfs and what it'll need and how I might minimize its size. Has anybody had any luck with getting a small RFS created as the rootfs section and mounting it? I'll be focusing on this soon.... I'm attaching my .config file for reference. Hopefully it comes through w/the mail list. Steve
