Introduce

use arduino by esp32 Developing programs is very convenient , But sometimes you need to test the program ,arduino Usually the compilation speed is very slow , As short as tens of seconds , As long as two or three minutes , It's a long time to wait .

therefore , Usually after a program stabilizes , We will compile the program into firmware , Convenient for later burning .

The firmware has been compiled into binary executable files from the source code , So upload the same program to esp32 when , There is no need to compile , You can directly burn binary executable programs to esp32 The development board can .

  open

  Select model

  Come in like this , That means we have no problem with the burning tool .

arduino Compile the program and generate bin The firmware  

（1） stay arduino Middle click item , Export compiled binaries

（2） Under the project folder, the generated bin file

(3) To arduino The cache of the software compiler can see the complete bin The firmware , Including partition firmware and firmware compiled from our application .

 （4） Choose these two firmware , Then fill in the appropriate burning address ( According to these two bin Adjust the size of the file , For example, my first bin File is 3k, So the second one bin File my burning address is 0x04000, That is to say 4k As the starting space for burning ）

  Results after the program burning is completed , Open the serial port to view the program execution information , It can be found that there are exceptions .

 （5） It turns out that here should burn several bin Of documents , Not just one , Like Android , Yes bootloader What? .

The first two documents should be burned

The latter two documents should be burned

  Burn address see here

  Okay , now .

（6） Now we choose to burn the file again , Try

  Then open the serial port and have a look , Here's the picture , It's all right

(7) Of course , We can put these four bin The file is combined into a bin file

Just click on combinebin that will do

  After synthesis , He will pop up a folder , After synthesis bin The document is called target.bin Put it under this folder

  If we want to burn this synthesized bin file , It needs to be done , Just select this target.bin file , And fill in the burning address , Click on start that will do  

alike , We can check whether the program is running normally through the serial port （ The following figure shows that the program is running normally ）.
