Set up The Toolchain
64-bit Linux：
https://dl.espressif.com/dl/toolchains/preview/xtensa-esp32s2-elf-gcc8_2_0-esp32s2-
dev-4-g3a626e-linux-amd64.tar.gz
32-bit Linux：

dev-4-g3a626e-linux-i686.tar.gz
1. Unzip the file to ~/esp directory:
64-bit Linux：
mkdir󰲧-p󰲧~/esp
cd󰲧~/esp
tar󰲧-xzf󰲧~/Downloads/xtensa-esp32s2-elf-gcc8_2_0-esp32s2-dev-4-g3a626e-linux-amd64.tar.gz
32-bit Linux：

2. The toolchain will be unzipped to ~/esp/xtensa-esp32s2-elf/ directory.
Add the following to ~/.profile:
export󰲧PATH="$HOME/esp/xtensa-esp32s2-elf/bin:$PATH"
Optionally, add the following to ~/.profile:
alias󰲧get_esp32s2='export󰲧PATH="$HOME/esp/xtensa-esp32s2-elf/bin:$PATH"'
3. Re-log in to validate .profile. Run the following to check PATH:
