Not able to enter bootloader mode on ESP32C3

Hi, i’m having trouble entering bootloader mode with this board. I’ve tried holding down the boot button and connecting to the PC. I’ve also tried holding down the boot button and hitting the reset button simultaneously. I’ve tried on 2 different boards. Neither of these approaches are working. What am I doing wrong?

What is the result when calling ftom the command line: chip_id

Do the messages start with: v4.4
Found 1 serial ports
Serial port /dev/ttyACM0
Detecting chip type... ESP32-C3
Chip is ESP32-C3 (revision v0.3)
Features: WiFi, BLE
Crystal is 40MHz
MAC: 10:91:a8:01:ea:f0
Uploading stub...

Stub running...

After that, aborts here as well, but at least the last lines show, that the bootloader was started.

Hello Jon,

Were you able to enter bootloader mode? I’m struggling with the same problem.

How about adding a pull-up resistor to D8?
