  经过几天的连续奋战,uclinux for bf561内核基本上启动完成,终于可以休息一下了!看看:

  Linux version (wmz@gtw.com) (vdsp 4.5) #2 Tue Sep 25 11:24:43 CST 2007

  Blackfin support (C) 2004-2007 Analog Devices, Inc.

  Compiled for ADSP-BF561 Rev 0.3

  Blackfin Linux support by linux.org/">http://blackfin.uclinux.org/

  Processor Speed: 600 MHz core clock and 100 Mhz System Clock

  Board Memory: 4MB

  Kernel Managed Memory: 4MB

  Memory map:

  text = 0x00010000-0x000639f0

  init = 0x000639f0-0x000a2130

  data = 0x000a6b84-0x000aacbc

  stack = 0x000a8000-0x000aa000

  bss = 0x000aacbc-0x000aacbc

  available = 0x000aacbc-0x003ff000

  Data Cache Enabled

  Hardware Trace Enabled

  Built 1 zonelists. Total pages: 1016

  Kernel command line:

  Configuring Blackfin Priority Driven Interrupts

  PID hash table entries: 16 (order: 4, 64 bytes)

  Dentry cache hash table entries: 512 (order: -1, 2048 bytes)

  Inode-cache hash table entries: 256 (order: -2, 1024 bytes)

  Physical pages: 3ff

  Memory available: 3392k/3429k RAM, (249k init code, 334k kernel code, 0k data, 0k dma)

  Blackfin Scratchpad data SRAM: 4 KB

  Blackfin DATA_A SRAM: 16 KB

  Blackfin DATA_B SRAM: 16 KB

  Blackfin Instruction SRAM: 16 KB

  Mount-cache hash table entries: 512

  Serial: Blackfin serial driver

  No filesystem could mount root, tried:

  Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

  虽然最终panic,但是估计只要在内核的末尾写入一个文件系统做为根系统就可以了(根据setup_arch中的相关提示),或者加载NorFlash / NandFlash的驱动并在上面建立相应的文件系统应该也是可以的。
