mruby-esp32-app-mirb に再挑戦する。

ssh git@github.com できないと後で git clone mruby-esp32-app-mirb が面倒。

$ ssh -v -T git@github.com

https://github.com/mruby-esp32/mruby-esp32-app-mirb

$ sudo apt-get install build-essentials
$ sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial
$ sudo apt-get install ruby
$ cd
$ mkdir esp32-setup
$ cd esp32-setup
$ wget --no-check-certificate https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-73-ge28a011-5.2.0.tar.gz
$ cd ..
$ mkdir esp
$ cd esp
$ tar -xzf ../esp32-setup/xtensa-esp32-elf-linux64-1.22.0-73-ge28a011-5.2.0.tar.gz 
$ export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH
$ git clone --recursive https://github.com/espressif/esp-idf.git
$ export IDF_PATH=$HOME/esp/esp-idf
$ git clone --recursive https://github.com/mruby-esp32/mruby-esp32-app-mirb.git
$ cd mruby-esp32-app-mirb

上述の "mirb_task", 8192 は 81920 に増やしておく。(必要)

$ tail main/main.c
  mirb_main(1, argv);

  esp_restart();
}

void
app_main()
{
  xTaskCreate(&mirb_task, "mirb_task", 81920, NULL, 5, NULL);
}
$ make menuconfig

# Serial flasher config > Default serial port => /dev/ttyS4 (COM4の場合)
# Component config ---> ESP32-specific
#  > Initialize Task Watchdog Timer on startup => unchecked (なんだか不安定だったので切った)
#  > Event loop task stack size => 40960 (後ろに0をつけて10倍にしたが、こっちは効果不明)
$ make

$ sudo chmod 777 /dev/ttyS4
$ make flash

$ picocom -b 115200 /dev/ttyS4
