ESP32-C6 Feather crashes and goes into safe mode when connecting to USB web workflow #9599
Description
CircuitPython version
Adafruit CircuitPython 9.1.3 on 2024-08-29; Adafruit Feather ESP32-C6 4MB Flash No PSRAM with ESP32C6Code/REPL
import time
import board
import digitalio
led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT
while True:
led.value = True
time.sleep(0.5)
led.value = False
time.sleep(0.5)Behavior
When running the blink code above, I try to initiate a connection with https://code-beta.circuitpython.org/ over USB. Once the board connects, the onboard LED stops blinking and I get this message in the serial console:
connected
soft reboot
Auto-reload is off.
Running in safe mode! Not running saved code.
You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Unable to allocate to the heap.
Please file an issue with your program at github.com/adafruit/circuitpython/issues.
Press reset to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
Description
I came across this while testing fixes related to this issue. Mainly that when the board is running code that has a blocking time.sleep delay in the loop it seems to also block connecting to the web editor.
When I connected to the code editor after freshly installing CircuitPython, I was able to connect right away (running the default print("hello world"). After saving the blink code and then trying to reconnect to the editor, I hit the safe mode error. I've been able to repeat the safe mode error consistently.
