  58. 

  59. 	export CROSS_COMPILE=your-cross-compile-prefix
    60. 

  60. 	cd u-boot
    61. 

  61. 	make distclean
    62. 

  62. 	make MPC8349ADS_config
    63. 

  63. 	make
    64.

  65. 5. Downloading and Flashing Images
    66.

  69. 	loadb
    70. 

  70. 	[Drop to kermit:
    71.

  79.         tftp 10000 u-boot.bin
    80.

  81. 5.1 Reflash U-boot Image using U-boot
    82. 

  82. 

  83.     tftp 10000 u-boot.bin
    84. 

  84.     protect off fe000000 fe09ffff
    85. 

  85.     erase fe000000 fe09ffff
    86. 

  86. 

  87.     cp.b 10000 fe000000 xxxx
    88. 

  88. or
    89. 

  89.     cp.b 10000 fe000000 a0000
    90.

  91. You might have to supply the correct byte count for 'xxxx' from
    92. 

  92. the TFTP.  Maybe a0000 will work too, that corresponds to the
    93. 

  93. erased sectors.
