FLASH_DOWNLOAD_TOOLS_v2.4_150924

1.fix the bug that tool does not show the MAC correctly for 48bit version of EFUSE.
2.update MAC reading functions

Note: 
Default MAC addresses our latest chips begins with "5CCF7F",
Please do not hard-code it with "18FE34" in your code.
AP : 5E-CF-7F-xx-xx-xx
STA: 5C-CF-7F-xx-xx-xx


FLASH_DOWNLOAD_TOOLS_v2.3_150916

add efuse check function.
add an option that tool just download the original binaries without changing anything.
add RFInit mode option:(byte[114] of init_data.bin)
0: RF init no RF CAL, using all RF CAL data in flash, it takes about 2ms for RF init 
1: RF init only do TX power control CAL, others using RF CAL data in flash , it takes about 20ms for RF init 
3: RF init do all RF CAL, it takes about 200ms for RF init """) 

#==============================================================
UPDATE: SOURCE CODE of flash_download_tool 
Functionally same as FLASH_DOWNLOAD_TOOLS_v1.2_150512.

To make it runnable, you need these python modules:
1. python2.6 /python 2.7
2. wxpython3.0 or above
3. pyserial
4. xlrd

For linux, you need to replace "COM1" with "/dev/ttyS0".


FLASH_DOWNLOAD_TOOLS_v1.2_150512

Fix some hints&tips


FLASH_DOWNLOAD_TOOLS_v1.1_150511

Support new flash size.
DO NOT SUPPORT : 7:4MB-C2(2048KB+2048KB)


FLASH_DOWNLOAD_TOOLS_v1.0_150508

Pay attention to the tips and hints in this tool.

NOTE:(IMPORTANT!)
The spi settings in the flash download tool will overwrite the setting during the compile procedure(at first serveral bytes from 0x0).
Make sure the settings are accord with the compile procedure.
The original binary will not be changed.
You can find the configured binaries in FLASH_DOWNLOAD_TOOLS/bin_tmp after the download is finished.
Especially for bootvxx.bin, it will not change and keep default settings for spi mode.
Also , you can press "CombineBin" button to get a combined binary which is already set to the mode you choose.

The flash mode are defined in the 2nd and 3rd( count from 0) byte at flash address 0x0.
Bootloader will read this bytes out and changed spi mode and size mode immediately. So this is very important for your production.

3)DIO,for flash that support dual r/w operation(e.g. W25Q &W25X)
4)DOUT, for flash that support dual read operation(e.g. W25Q &W25X)
4.Flash size: effect the flash operation APIs and bootloader address.
5.combine bine button: generate the bin file of the whole size.
6.ID BIND:just provide a way that write chip id in the flash addr.Need at least 2 sector(2*4096Bytes)
