ESP32C3 + ST7789 incompatible with ESP Arduino board package > 2.0.4

[moeburn]

1. When compiling ESP32C3 + ST7789, it compiles successfully, but I get "Guru Meditation Error: Core 0 panic'ed (Store access fault). Exception was unhandled." and a bootloop.
2. Arduino IDE
3. Tried the latest TFT_eSPI library version 2.5.43, as well as 2.5.34 and 2.5.0
4. Tried board packages 3.1.1, 3.0.4, 2.0.17, and 2.0.4 (since it was mentioned on this library's readme). Only 2.0.4 worked.
5. ESP32C3
6. ST7789
7. SPI

Plus further information as appropriate to the problem:

1. TFT to processor connections used - #define TFT_MOSI 6 //SDA
   #define TFT_SCLK 4
   #define TFT_DC 1

#define TFT_RST 0
2. A zip file containing your setup file User_Setup.zip

3. A zip file containing a simple and complete example sketch that demonstrates the problem but needs no special hardware sensors or libraries. chrisvoc.zip
4. "Guru Meditation Error: Core 0 panic'ed (Store access fault). Exception was unhandled."

I can second that. Just spent an hour trying to get a working esp8266 project running on my Waveshare ESP32 C3. The exception loop starts with the tft.init() call and results in the same Guru Meditation Error as described.

Try with these. Extract and copy the files to "..\Arduino\libraries\TFT_eSPI\Processors" . Recompile and upload. (make sure to save a copy of your original files first, just in case)
