 Suppose we want to copy (burn) a file with 0x1a6c0 byes from RAM
address 0xA1080000 to flash address 0x0, i.e., the u-boot.bin.
 Step 1: erase the specified range (0x0 to 0x7FFFF).
 Flash should be erased before copying files.
 u-boot$ protect off 0 7ffff
 u-boot$ erase 0 7ffff
 Step 2: copy the file from RAM to flash.
 u-boot$ cp.b a1080000 0 1a6c0
 Step 3: now, you can reset PXA270 and check the message of U-Boot.
 Also, you can remove the JTAG from PXA270 because now you have a U-Boot
program on your PXA270 and there is no need to use Domingo.
 In case your U-Boot is broken, please use Domingo to copy a new one.

 Microtime provides a program “diag” that can help developers diagnose
peripheral devices on PXA270, e.g., SDRAM, flash, LED, CCD, LCD, etc.
You can diagnose the target board by yourself first if you think it is
broken.
 Step 1: download diag_ram.bin (diag_ram.bin).
 u-boot$ tftp a1080000 diag_ram.bin
 Step 2: copy diag_ram.bin to flash address 0x40000 on PXA270.
 u-boot$ cp.b a1080000 40000 <size>
 Step 3: reset PXA270 and then you will
see the menu of diag on the LCD.
