ESP32-C3 and RISC V

June 16, 2022

Dig a bit into esp-idf

I type "esp_idf" then "which idf.py" and get:

/u1/Projects/RISCV/esp32c3/esp-idf/tools/idf.py

Note that typing "idf.py" gives a bunch of information.

At least this is python, which from among many options is among the better ones. Thanks be to God it isn't Tcl or Java. I've had enough wretched slow Java based tools (yes, Eclipse, I am looking at you!).

esptool

This is "~/.espressif/python_env/idf5.0_py3.10_env/bin/esptool.py" and you can run it!

You can also directly run "idf_monitor.py" which runs /u1/Projects/RISCV/esp32c3/esp-idf/tools/idf_monitor.py

So, things are split between stuff that you got via the initial clone (which is in /u1/Projects/RISCV/esp32c3/esp-idf/) and stuff the install script installed (which is in /home/tom/.espressif).

What does a project look like?

We are just doing a recon, not trying to dig out every detail. Let's look at the last example project I worked on:

cd /u1/Projects/RISCV/esp32c3/blink

In here we have "sdkconfig" which has a bunch of options. The action is in the "build" directory. To have any clue about what is going on here, a person will need to learn about "build ninja":

Just for the record, the "build.ninja" file for the simple blink demo is 14,411 lines !! And indeed the "build.ninja" file is the equivalent of the Makefile for build-ninja.

idf.py -v build

This gives a lot of details. Many of the command lines are extremely long. Here is my trimmed versions after doing a "touch" of the only source file in the blink project:

cd /u1/Projects/riscv/esp32c3/blink
touch main/*.c
idf.py -v build
