Hello - I’m learning to build executable code for my XIAO-ESP32C6 processor using PlatformIO and following the guidance offered here: XIAO ESP32C6 with PlatformIO | Seeed Studio Wiki
I’d appreciate any hints for solving my build problem.
Thanks,
Jim
Source code:
#include <Arduino.h>
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Hi there,
Season’s Greetings. 
SO , can you show you PlatformIO.ini file contents ?
Also have you done a clean build first?
How did you setup your build environment?

Hi PJ - Below please find my PlatformIO.ini file. - Cheers - Jim

Also, I followed the instructions given here: XIAO ESP32C6 with PlatformIO | Seeed Studio Wiki
As to doing a clean build first, I don’t know what you are referring to. - Jim
Thank you, grobasoz. I ran the pip command and as best I can tell rich_click is installed. For example, I see the following in the Terminal output: “Successfully installed rich_click-1.9.4”. However, I’m still getting the same build error within PlatformIO as shown in the following:

In case helpful, here’s some data regarding my installation of rich_click:
framewk 125= pip install 'rich_click'
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: rich_click in ./.local/lib/python3.13/site-packages (1.9.4)
Requirement already satisfied: click>=8 in /usr/lib/python3.13/site-packages (from rich_click) (8.1.7)
Requirement already satisfied: rich>=12 in ./.local/lib/python3.13/site-packages (from rich_click) (14.2.0)
Requirement already satisfied: markdown-it-py>=2.2.0 in ./.local/lib/python3.13/site-packages (from rich>=12->rich_click) (4.0.0)
Requirement already satisfied: pygments<3.0.0,>=2.13.0 in /usr/lib/python3.13/site-packages (from rich>=12->rich_click) (2.18.0)
Requirement already satisfied: mdurl~=0.1 in ./.local/lib/python3.13/site-packages (from markdown-it-py>=2.2.0->rich>=12->rich_click) (0.1.2)
In that case I’m not sure what the issue could be. It may be a red herring error, where the underlying problem is caused by conflicting esptool versions?
You could try a …
pio pkg update -g -t tool-esptoolpy

I generally only use espressif32 when supplying the platform in the platformio ini file.
I’m now able to build and burn a blink app to my XIAO-ESP32C6. The key was to install the extension “pioarduino IDE” in VSCode. Thanks for everyone for helping me!

Thanks for the update.
The pioarduino extension is a great alternative to PlatformIO (which should have worked as well).
For those wanting to stick with PlatformIO, the solution I found to work was to install rich-click and intelhex to the PlatformIO environment… eg (for Windows)
C:\Users<user>.platformio\penv\Scripts\python.exe -m pip install rich-click
C:\Users<user>.platformio\penv\Scripts\python.exe -m pip install intelhex
I also had to “update” esp32-hal-i2c-slave.c with suggested build warnings…
warning: implicit declaration of function 'i2c_ll_slave_set_fifo_mode'; did you mean 'i2c_ll_enable_fifo_mode'? [-Wimplicit-function-declaration]
378 | i2c_ll_slave_set_fifo_mode(i2c->dev, true);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
| i2c_ll_enable_fifo_mode
NB: I haven’t tested these I2C changes.
