Hello, I'm trying to boot my system with a cramfs filesystem in NOR flash. The kernel shows the following output when booting: physmap flash device: 2000000 at 8000000 RedBoot partition parsing not available davinciflash.0: Found 1 x16 devices at 0x0 in 16-bit bank Amd/Fujitsu Extended Query Table at 0x0041 davinciflash.0: CFI does not contain boot bank location. Assuming top. number of CFI chips: 1 cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness. Creating 5 MTD partitions on "davinciflash.0": 0x00000000-0x00020000 : "bootloader" 0x00020000-0x00040000 : "params" 0x00040000-0x00060000 : "sw_params" 0x00060000-0x005ec000 : "kernel" mtd: partition "kernel" doesn't end on an erase block -- force read-only 0x005ec000-0x02000000 : "filesystem" RAMDISK: cramfs filesystem found at block 0 RAMDISK: Loading 1304KiB [1 disk] into ram disk... done. VFS: Mounted root (cramfs filesystem) readonly. VFS: Cannot open root device "ram0" or unknown-block(0,0) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) I've verified that the cramfs image contains /dev/ram0. My uboot commands are: bootargs=mem=30M console=ttyS0,115200n8 root=/dev/ram0 ro init=/startup ip=off lpj=741376 bootcmd=cp.b 0x021a0000 0x80900000 0x146040; bootm 0x02060000 0x80900000 Any idea what I'm doing wrong? Thanks for any help. -Steve |
