************************************************
|
|
MSYS2 environment is now ready to use ESP-IDF.
|
|
|
|
1) Run 'source /etc/profile' to add the toolchain to
|
|
your path in this terminal. This command produces no output.
|
|
You only need to do this once, future terminals do this
|
|
automatically when opened.
|
|
|
|
2) After ESP-IDF is set up (see setup guide), edit the file
|
|
`cygpath -w /etc/profile`
|
|
and add a line to set the variable IDF_PATH so it points to the
|
|
IDF directory, ie:
|
|
|
|
export IDF_PATH=/c/path/to/esp-idf/directory
|
|
|
|
