I have some questions about using FLASH_DOWNLOAD_TOOL in production.
バイナリファイル.binをwindows上の書き込みソフトウェアesp flash download toolを使って書き込みます。 esp flash download toolのダウンロード; pcとesp-wroom-02はuartで接続します(usbシリアル変換が必要、ロジック電圧は3.3vです。一般的なusb-rs232c変換ケーブルは使えません)。. 690 Bibo Road Block 2 Suite 204, Zhangjiang Shanghai, China.

Start conditions:
1. We have a pre-signed and pre-encrypted binary for the bootloader, partition table, and factory app.
2. We are using 192-bit keys for flash encryption and secure boot.
Esp Flash Download Tool Mac Free3. We need to burn to eFuse some additional parameters, that are not listed at security.conf file and this part of manualEsp Flash Download Tool
- burn_efuse FLASH_CRYPT_CONFIG 0xF
- burn_efuse CODING_SCHEME 1
- burn_efuse FLASH_CRYPT_CNT
- write_protect_efuse FLASH_CRYPT_CNT
- burn_efuse CONSOLE_DEBUG_DISABLE
- burn_efuse ABS_DONE_0
4. Also, we need to log all console out from espefuse.py and esptool.py to separate files for every controller (_MAC_ADDRESS_-flash.log and _MAC_ADDRESS_-efuse.log for example).
Now we are using this bash script to flash FW end burn eFuse. There is no handling for esptool and espefuse exit codes yet, and its work fine, but only for single programmer setup.
According to this workflow scheme
it looks like FLASH_DOWNLOAD_TOOL requires not-signed and not-encrypted bin images will re-sign and re-encrypt them every time. And it is not clear, does it can burn additional efuses and work with 192-bit keys.
So, the questions are:
1. Can FLASH_DOWNLOAD_TOOL be configured for our conditions?
2. If not - can you provide the source code of FLASH_DOWNLOAD_TOOL for customization.
3. Additional question - we are using the ESP-prog programmer, from Linux PC we can flash at 2M baud, but from WIN10 PC only 1.152.000 baud can be chosen. Is it possible to set up higher baud rate on WIN10 PC?
Working with ESP8266 and NodeMCU can be very easy, or very challenging! I’ve been fortunate to have good luck but I’ve fielded may questions from people that have been having trouble.
If you are on a Mac (or Linux), unfortunately there are not as many GUI options as there are on Windows. There is however one solid option that has been my go to method.
Setting up the software environment
First things first, think about the hardware, it is important to know what UART interface that you plan to program with. I’m a FTDI guy, I’ve always had good luck with the parts, they might no be the cheapest but I’ve found that they keep there drivers up to date, and overall have great quality. (no comments on FTDI Gate) Download Esp Online
ALWAYS be sure to update your drivers. Especially on Yosemite because Apple’s default is to use their own version of libftdi instead of the official FTDI VCP drivers. This for certain does not work with the FT232X series parts.
You may download the FTDI VCP drivers here and install them:
Other drivers that might be useful if you are not using FTDI are:
SiLabs
Prolific
Be advised that some low cost boards (including the official NodeMCU dev board) use a very cheap USB to UART chip, the driver can be found here:
Once you know that your UART is working, now it is time to install esptool.py
You may download esptool here:
Once downloaded, create a folder and place esptool.py inside
open the terminal application and navigate to this folder using cd
You will also need to download the latest NodeMCU firmware binary from here:
There are two options for NodeMCU builds, one which includes floating point and one that does not. I highly recommend the binary without floating point because it does not leave much memory space for running code.
After download, place this bin file in the same folder.
esptool is written in python, as such it requires a working python environment. Luckily, OS X comes with Python pre-installed. pySerial is one dependency is not included but can be easily added using PIP. Esp Free Download
You may install pySerial with the following command
Preparing the ESP8266
ESP8266 has a built in UART boot loader that is used to program new binaries. The boot loader is entered if GPIO0 is tied to GND when ESP8266 comes out of reset or is powered on. Most modules either have a push button or a pad where a wire my be soldered to. Use this pin/pad or button to tie GPIO0 to ground and power on the module.
CH_PD must be tied to VCC to be functional, this is equivalent to ’Chip Power Down”.
Some ESP8266 modules including ESP-03 also require GPIO15 to be tied to ground at all times for proper function.
FlashingEsp Easy Flash Tool
With the software environment setup and the ESP8266 in bootloader mode, its time to finish the flashing process.
You will need to find the path to the UART. In OS X these are typically in the /dev/ path and typically begin with “tty.”. List these paths with:
ls /dev/tty.*
For FTDI based chips it is typically “tty.usbserial-xxxxxxxx”, find the correct path for your UART and copy it to the clip board.
The final step is to program the chip. To do this, use the following command to flash. Be sure to replace “/dev/tty.usbserial-FTSMF90L” with the path to your UART and “nodemcu_integer_0.9.6-dev_20150406.bin” with the name of the firmware file that you wish to download.
