I think I downloaded to a wrong address, then cause the whole module dead, ESP-12 module always ON red and blue leds. So I need to erase all to do re-flash.

what is the alternative in case we do not have a windows os?

I tried to use the provided python tool but it requires py-exec that is only provided for windows :(

I think "+" means version 1.2 or higher. As example boot version 1.4+ means (also) boot_v1.4(b1).bin.

You can use boot_v1.2.bin but according the fact that newer version (1.2+) is supported, you should rather use the latest boot version which is boot_v1.4(b1).bin at the moment.

my ESP is ESPWROOM02.
I got Chip sync error message in cmd-like window, and fail message with red color in the box.
I have configured all the hardware correctly, and my esp sent proper message in normal mode with tx rx, so I think it's not the hardware problem.
Can someone help me, what should I do?

In fact a software toolkit supporting One-Press-Programming is already available for months under windows operating systems, which issues RTS signal to control the power/chip_en/nReset for a hardware reboot, and issue DTR signal to toggle the GPIO0 for flash burning timing automatically. Meanwhile, the software toolkit is not just a download toolkit, but one in combination of debug and dowanload capabilities with many interesting features more than listed below.

You could get the software toolkit downloaded from outside China: https://github.com/Anylinkin/ESP8266/tr ... /S8266WIFI from inside China: http://pan.baidu.com/s/1pJy3bUN : open the folder and download freely the compressed file ESP8266EX_Debug_and_Download_Toolkit_Vx.x.x.tar only if you are familiar with English. And there is an English user's manual document in the downloaded package. The toolkit support language switch between Chinese and English as well.

Features for your information

1. Auto-Search the COM port number and baud rate an ESP8266EX module attached, without any troubles due to forget or not know the baud rate of an attached Espressif module.

2. Adaptive Baud Rate matching with 74880bps supported, to avoid unread codes during bootstrap which is helpful for cause-locating and trouble-shooting.

3. Supporting COM port number above 10 without any necessity to adjust the COM number from the computer side.

4. Capable of communicating both in Hexadecimal and normal ASCII mode.

5. Available with a quick launch to some frequently used AT commands.

6. Available with a capability to boot the ESP8266EX module from serial port.

7. Available with a flexible flash downloading interface
- With On-Press-Program® (OPP®) capabilities
- Supporting various types of Flash Map and SPI configuration
- With more debug information output for debugging,
- Supporting GPIO selection for LED indicator, and
- Supporting downloading speed selection during flash programming for different performance of hardware

8. Supporting various types of modules based on ESP8266EX SOC

9. Supporting various Windows Operation Systems.

10. More to be found out.

The last but not the least, I also strongly suggest to use the download tool by Espressif if possible. Meanwhile, if you expect to get some more features, you may have a try with the software toolkit, as many developpers said it brings about convenience.

Hope it will be helpful.

I second that, using DTR/RTS to drive GPIO0 and Reset is a brilliantly simple idea and makes life much easier.

Can you please add the same functionality as in esptool - controlling DTR and RST lines for automatic reset -> switch to UART boot mode when pressing START and reset -> switch to SPI boot mode afterwards (when pressing STOP)?

esptool uses the RTS and DTR modem status lines to automatically enter the bootloader.
Connect RTS to CH_PD (which is used as active-low reset) and DTR to GPIO0.

Thank you for sharing and updating!

I will come to look at this issue and look forward to!

The secret modification overrides the option chosen when compiling. I think this should be avoided or at least documented.

乐鑫官网上应该由独立的连接发布各种SDK、工具、代码、文档等等资料，这样才能提高开发环境的易用性、统一性，让用户集中精力做开发工作，而不是在论坛里翻资料，还为各种版本的资料头疼。让工程师感觉是在和diy的FANS一起在搞尝试，而忽略了他们是在做产品开发！
芯片做的好是一方面，开发环境是吸引工程应用的另一方面，请参考TI、ST等公司的文档、工具链、技术支持的运行模式。
希望乐鑫越做越好！

esp_iot_sdk can work in different flash sizes and flash maps, more details are in documentation 2A-ESP8266-SDK__Getting_Started_Guide.

Please use Espressif Flash Download Tool to download bin files into flash, and choose the corresponding flash map to your compilation.
Otherwise you may have many SPI flash related problems, because of the mismatch of flash map compiling and flash map downloading.
