Building ESP32 toolchain on ARM (Armbian Raspbian)
Credits to jrullan original from arduino-esp32 issue
Another tutorial to build the toolchain from Kolban’s book on ESP32
Another tutorial to build the toolchain from ESP32 forum
Download ready build toolchain from Neil Kolbans website: toolchain
Video tutorial to build the toolchain from ESP32 – Development environment on PI
Install Arduino IDE on Armbian script
To install ESP32 toolchain on Armbian:
1. Install Prerequisites:
|
1 |
sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial |
2. Install Dependencies:
|
1 |
sudo apt-get install gawk grep gettext python-dev automake texinfo help2man libtool libtool-bin |
3. Download crosstool-NG
|
1 2 3 4 |
cd ~/esp git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git cd crosstool-NG ./bootstrap && ./configure --enable-local && make install |
4. Build
|
1 2 3 |
./ct-ng xtensa-esp32-elf ./ct-ng build chmod -R u+w builds/xtensa-esp32-elf |
5. Toolchain will be built in ~/esp/crosstool-NG/builds/xtensa-esp32-elf.
Follow instructions for standard setup to add the toolchain to your PATH.
Installation output (So you know what to expect!)
