Hi @SeanTheITGuy

I tried to flash my Spotpear ESP32C3 LCD 1.4 device with the version 9.2.3 of CircuitPython from that link:
https://circuitpython.org/board/spotpear_esp32c3_lcd_1_44. After a small fix on the CircuitPython site, I was able to flash it. However, it seems that the firmware makes the board rebooting over and over, with the following errors:

ESP-ROM:esp32c3-api1-20210207
Build:Feb  7 2021
rst:0xc (RTC_SW_CPU_RST),boot:0x8 (SPI_FAST_FLASH_BOOT)
Saved PC:0x40383246

I asked the following question on the CircuitPython forum https://forums.adafruit.com/viewtopic.php?t=216227.

Do you have an idea what could be making the board rebooting?
Are you experiencing the same with yours?

Thank you very much! Have a great day!

@gabriel-gagnon Can confirm this is not your problem. 9.2.3 does NOT work on this board. It results in, exactly as you say, a boot loop.
I went through the older versions, and it worked up to 9.2.1, but something was introduced in 9.2.2 that causes this issue.

If you can grab 9.2.1 from there and flash, you'll most likely find it works perfectly. I'm not sure what issue might have been introduced, but I will take a cursory glance when time allows, or hopefully someone with more knowledge than I will. I will file an issue tomorrow.

Thanks @SeanTheITGuy for your extremely fast feedback!
I'll have a try tomorrow or on Sunday.
Thank you very much!
