Advise on setup

lgLindstrom · November 19, 2018, 1:31pm

I recently purchased a ESP32-DevKitC-S1 from Espressif. It contains ESP32-SOLO-1 which is a stripped down ESP32 module.

It seems that I cant get it to work (i.e upload and start program ).

This is my configuration:
[global]
lib_deps =
GitHub - WebThingsIO/webthing-arduino: Simple server for ESP8266, ESP32, Ethernet, or WiFi101-compatible boards compliant with Mozilla's proposed WoT API
ArduinoJson

  [env:esp-dev]
  platform = espressif32
  board = esp32dev
  framework = arduino
  lib_deps =
      ${global.lib_deps}
      ESP Async WebServer
  lib_ignore =
        ArduinoMDNS
        WiFi101
  lib_ldf_mode = deep+

  monitor_speed = 115200
  monitor_port = com4

Have I missed some step here ?

Your platformio.ini setup should look like this:

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 115200

Simple and functional.
If you need to include any library, just install them from library manager and include the relevant header into your project.

lgLindstrom · November 20, 2018, 2:05pm

Not working any better …

This is my code:
void setup(void){
Serial.begin(115200);
Serial.println("");
Serial.print(“Setup ready”);
}

  void loop(void){
      delay(500);
      Serial.print(".");
   }

This is the output from serial monitor:

Here is a simple project that work’s just fine:

lgLindstrom · November 21, 2018, 6:42pm

Stil not work for me… although I’ve copied your setup.

From the monitor window, the only difference I can see is

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

Your window says boot:0x1e

I don’t have a clue about what that means.

Is there some driver to load for the serial port or some firmware to flash to the card ?

botofancalin · November 23, 2018, 6:37pm

No. No firmware or driver needed.
Windows will install the drivers automatically once you connect the board to PC USB.
The program compiled from the code is the actual firmware.

The only difference is that i used a DOIT ESP32 Devkit with ESP32-wroom module on it.
This one use a standard (dual core) esp32 on it.
I think your module use some single core ESP32 variant.

lgLindstrom · November 24, 2018, 12:15pm

Yes, you are correct. My module is ESP32-SOLO-1

I am kind of lost here, kindly suggest next step for me to take, to get going with this development board…

maxgerhardt · November 24, 2018, 2:53pm

Can you get the board working the ESP-IDF? What settings do you have to change in ESP-IDF to make the board work?

lgLindstrom · November 25, 2018, 4:42pm

Never worked with ESP-IDF, can you give me a pointer ?

maxgerhardt · November 25, 2018, 5:32pm

Well ESP-IDF is also integrated in PIO, so you should try to configure and upload this example first: platform-espressif32/examples/espidf-blink at master · platformio/platform-espressif32 · GitHub

For the native ESP-IDF start at GitHub - espressif/esp-idf: Espressif IoT Development Framework. Official development framework for Espressif SoCs. and remember to follow ESP32-SOLO-1 on DevKitC_V4 not working - ESP32 Forum (FreeRTOS on first core only in sdkconfig.h).

lgLindstrom · November 25, 2018, 7:27pm

Tanks,

When reading, I came across this

When using ESP32-DevKitC board with ESP32-SOLO-1 module, enable single core mode 
([CONFIG_FREERTOS_UNICORE](https://docs.espressif.com/projects/esp-idf/en/latest/api- 
reference/kconfig.html#config-freertos-unicore)) in menuconfig before flashing example applications.

Is it part of platformio,? how do I set it ?

maxgerhardt · November 25, 2018, 7:30pm

As https://dl.espressif.com/doc/esp-idf/latest/api-reference/kconfig.html says the resulting configuration from the kconfig program will be stored in the sdkconfig.h. When you create a PIO project with IDF as the framework you also get a default sdkconfig.h. In there search for FREERTOS_UNICORE and #define it to 1, or add it if it is not there.

lgLindstrom · December 16, 2018, 1:57pm

Is there a way to set this variable in Arduino framework??

botofancalin · December 19, 2018, 6:10am

Yes.

You can do this in 2 ways:

this should enable unicore for all builds:
Go to C:\Users[your user].platformio\packages\framework-arduinoespressif32\tools\sdk\sdkconfig
At line 472 you have “CONFIG_FREERTOS_UNICORE=”
Set “CONFIG_FREERTOS_UNICORE=y”
Save the sdkconfig file then build your project.
this should configure unicore for current project:
in platformio.ini env settings, add:
“build_flags = -DCONFIG_FREERTOS_UNICORE=1”

lgLindstrom · February 4, 2019, 2:01pm

Old thread, but still not solved ( I’ve done other things for a while ).
REFRESH,
I have a ESP32-DevKitC-S1 board from Espressif. It contains ESP32-SOLO-1 which is a stripped down ESP32 module (Just one core )
I cant get it to work.

My configuration.

[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino
build_flags = -DCONFIG_FREERTOS_UNICORE=1
monitor_speed = 115200

My code:

#include <Arduino.h>
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}
void loop() {
      delay(500);
      Serial.print(".");
}

The terminals shows following during upload process:

So, anyone who can help ??

maxgerhardt · February 4, 2019, 5:58pm

Could you get it to work within the Arduino IDE? With which settings?

lgLindstrom · February 5, 2019, 9:04am

I have not tested, but this must be wrong…

but I cant find any support for

lgLindstrom · February 6, 2019, 7:29pm

Hi

I changed board type, to esp32doit-devkit-v1 and now I have the following error.
What is menuconfig ?

maxgerhardt · February 6, 2019, 7:34pm

menuconfig (or rather make menuconfig) is the command you type in a ESP-IDF project will give you a terminal-UI to select ESP-IDF compilation options. This will ultimately create the sdkconfig file which has all the chosen macro values inside. See Project Configuration - ESP32 - — ESP-IDF Programming Guide latest documentation

From the output it seems like CONFIG_FREERTOS_UNICORE wasn ot set? build_flags = -DCONFIG_FREERTOS_UNICORE is still in your platformio.ini?

lgLindstrom · February 7, 2019, 11:32am

Yes it is,
Current config.

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 115200
build_flags = -DCONFIG_FREERTOS_UNICORE=YES

Do I need to install the ESP-IDF although I am only using Arduino framework ??
