1.fix error when downloading a binary that is not aligned.
2.fix error when loading default settings


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.

release note:
1.fix the flash erase bug
2.fix the exception for w25x series flash,when using boot loader.
3.change the the download order, from low addr offset to high.

settings :
1.crystal: support 3 freq. 26m 40m 24m,choose the one you use.
2.spi speed:
spi flash read/write clk frequency.
3.spi mode :
1)QIO ,for flash that support quad r/w operation(e.g. W25Q)
2)QOUT,for flash that support quad read operation(e.g. W25Q)
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)

Thanks to Fredrik Ahlberg's outstanding work of esptool.py

esp_init_data_default.bin-->0x7c000
blank.bin ==> 0x7e000
devkey --> 0x3e000
eagle.app.v6.irom0text.bin-->0x40000
eagle.app.v6.flash.bin --> 0x0

CONFIG ITEMS: FRYSTAL FREQUENCY , SPI SPEED ,R/W MODE,SIZE
IF ENABLE ID BIND IS ENABLED , THE MAC ADDR WILL BE WITEN IN TO THE GIVEN ADDR.

WIRTEN IN PYTHON2.6 AND WXPYTHON2.8
THE MAIN LOOP IS IN frame_test.py.

BUG OR ADVICE CAN BE POST HERE.

costaud, thanks for the post.

Thanks!

it is possible to add functionality to control RTS/DTR uart pins,
which in next step controls ESP RESET/GPIO0 pins for automatically enter upload process?
RST LOW->DTR LOW->RST UP->DTR UP

and of course one more hard reset RST LOW->RST UP after programming process for bootup with new firmware

this is mod version of esptool.py

no, it is not possible to do it properly for each every available SoC mode and it's electrical specs without external drivers (e.g. two BSS138 + pullups/down per pin).
And any external driver breaks the "universality" in universal flash download tool, if you wish pin toggle feature for your circuit just add few lines of code and recompile the tool.

Thank you so much for fixing this.

hi

>> 6.ID BIND:just provide a way that write chip id in the flash addr.Need at least 2 sector(2*4096Bytes)

what is that mean:
flash download tool write the chip id to flash adress example 0x14000 with a auto routine and the fw is protected by self without any written code by user?
example: guy dump copy to other modul
boot code compare chip id with flash adress 0x14000
if not same boot is broken

do you can give a construction, please?

or mean this:
chip id is written to the flash addr that user given in bind;
user must controll in fw code byself -

Hi, how can I get source code of FLASH_DOWNLOAD_TOOLS_v0.9.6_150419.rar? Thanks in advance.
