When I fire up the board,the U-boot reports are as follows:
...
U-Boot 1.1.2 (May 10 2005 - 08:54:34)
CPU: MPC5200 v1.2 at 396 MHz Bus 132 MHz, IPB 66 MHz, PCI 33 MHz Board: Motorola MPC5200 (IceCube) I2C: 85 kHz, ready DRAM: 32 MB FLASH: 0 kB
^^^^^^^^^^^^^^ Problem here
Is it ok? What's the problem on "FLASH: 0 kB *** Warning - bad CRC, using default environment "? It can not find my flash on board?
Correct. Seems you don't have an IceCube (aka Lite5200) board. You will have to port U-Boot to your hartware.
