ESP32 Forum

Greeting!

I have just succeeded in flashing esp-wrover-kit development board under esp-idf. Now trying do the same thing under Arduino. I would ask for your help to fix the issue. May I report my procedure 1 stpe by 1 as below?

1, Following the guide on "Installation instructions for Debian / Ubuntu OS" (https://github.com/espressif/arduino-es ... _ubuntu.md), I went through the following steps.
1.1, "Install latest Arduino IDE from arduino.cc". The root directory that Arduino IDE is installed is ~/arduino-1.8.5.
1.2, "git clone arduino-esp32.git". The directory ~/Arduino is created at this step. And the git repository is cloned into ~/Arduino/hardware/espressif/esp32.
1.3, "Restart Arduino IDE". I think that we need to import "esp-wrover-kit" board by selecting "Tools -> Board ...", right? But I couldn't find the board type over there. Where can I find a guidance to add the board into Arduino IDE?

2, As introduced at https://github.com/espressif/arduino-es ... cs/make.md, using makeEspArduino "instead of the Arduino IDE makes it easier to do automated and production builds."
I prefer to use makeEspArduino, as well. So, tried steps as below.
2.1, git clone https://github.com/plerup/makeEspArduino.git. Then directory "makeEspArduino" is created.
2.2, I didn't install arduino-esp32 again since I had installed it at step 1.2.
2.3, changed DEFAULT_PORT to /dev/ttyUSB1 in makeEspArduino/tools/esptool.py
2.4, connected esp-wrover-kit dev board to my laptop via USB cable. I had succeeded in flashing the borad by typing the following command under ~/esp/esp-idf/examples/get-started/blink
make flash
That is, the physical connection works under esp-idf environment.
2.4,
cd makeEspArduino
make -f makeEspArduino.mk ESP_ROOT=~/Arduino/hardware/espressif/esp32 CHIP=esp32 DEMO=1 flash
2.5, I got log:

That proves that the same physical connection can make “flash” successful under esp-idf but get failure with arduino-esp32.
Could you check the log then let me know how to flash the board successfully under arduino-esp32 environment? And where is the app that “DEMO=1” points to?

Thanks!

Hi huaxiaozhong1,

Have you verified that you are using the same serial port number as you did when loading from esp-idf?

The only difference in loading procedure I see is that arduino-esp32 is currently using esptool.py v2.1 while esp-idf esptool.py v2.2.1.

Thanks for your rapid feedback. To keep the serial port as same, I changed the DEFAULT_PORT of USB port name from /dev/ttyUSB0 to /dev/ttyUSB1 in esptool.py. Let me try esptool.py v2.2.1 to arduino-esp32, to see what will happen

Hi krzychb,

I have just taken the following actions.

1, copied esptool.py from esp/esp-idf/components/esptool_py/esptool to ~/Arduino/hardware/espressif/esp32/tools, and changed DEFAULT_PORT to /dev/ttyUSB1.

2, cd makeEspArduino

3, make -f makeEspArduino.mk ESP_ROOT=~/Arduino/hardware/espressif/esp32 CHIP=esp32 DEMO=1 flash

4, The log that I got is below.

It is really like what I got under esp-idf environment when USB device name was set as /dev/ttyUSB0.

What next step would you suggest us to go?

Thanks,

Hi huaxiaozhong1 again

Reading https://github.com/plerup/makeEspArduin ... e-makefile it looks to me that you need to set UPLOAD_PORT in your makefile, not DEFAULT_PORT.

Hi krzychb,

Your guidance is really helpful!

The esp-wrover-kit dev board has been proved to work under EspArduino environment. My first evidence was got through the following steps.

1, The new actions should be taken based at all procedures ahead that I listed yesterday. Those include cloning arduino-esp32.git into directory ~/Arduino, installing arduino into ~/arduino-1.8.5, installing esp into ~/esp, cloning makeEspArduino.git into …/makeEspArduino and running some esp32 examples. E.g., “blink” can be built and flash under …/examples/blink.

2, alias espmake32="make -f ~/makeEspArduino/makeEspArduino.mk CHIP=esp32 ESP_ROOT=~/Arduino/hardware/espressif/esp32"

3,
cd ~/arduino-1.8.5/examples/01.Basics/Blink

4, Replace all “LED_BUILTIN”s with “2” in Blink.ino
Note: the test wants to blink green LED on the board. By analyzing ~/esp/esp-idf/examples/get-started/blink, the value should be set as “2”.

espmake32 flash

The green LED on the board started to blink

It is saying that the board could work with EspArduino.

Thank!

Now the case can be closed.
