ESP32-C3 bootloop

See original GitHub issue

I’ve an ESP32-C3 (2MB) but I’m unable to flash this through platformIO. It keeps resetting in a bootloop:

ESP-ROM:esp32c3-api1-20210207
Build:Feb  7 2021

I’ve tried setting platform = https://github.com/Jason2866/platform-espressif32/releases/download/v2.0.3-rc1/platform-espressif32-2.0.3-rc1.zip

But this does not work.

My full config:

platform = https://github.com/Jason2866/platform-espressif32/releases/download/v2.0.3-rc1/platform-espressif32-2.0.3-rc1.zip
board = esp32-c3-devkitm-1
board_build.filesystem = littlefs
framework = arduino
monitor_speed = 115200
upload_port = /dev/ttyUSB0
monitor_port = /dev/ttyUSB0
board_upload.flash_size = "2MB"
board_upload.maximum_size = 2097152
board_build.flash_mode = dio
board_build.f_flash = 40000000L

I’ve verified it is working with arduino IDE.

So verified, you have a board rev which is not supported from Arduino.

Ouuch, the advanced example uses a not possible GPIO in line23 int LED_PIN = 13; when mode qio is used. GPIO 12 and GPIO13 (page 12. in datasheet) are needed for QIO with SPI. It is always a bad idea to define a Led to fixed GPIO @hpsaturn
