Cannot download codes to CubeCell Dev-6502 Lora32

#1

Hi, anyone can help resolve the download codes problem? I had followed an instruction to hold on “USER” button when doing downloading codes to the CubeCell Dev-6502 Lora32 and then press “RST” button once. The setting of board in the tool is Heltec WiFi LoRa 32 V3. However, I did not succeed every time and showed error message: Global variables use 21944 bytes (7%) of dynamic memory, leaving 272968 bytes for local variables. Maximum is 294912 bytes.
esptool.py v4.5.1
Serial port COM10
Connecting…

A fatal error occurred: Failed to connect to ESP32: No serial data received.

You need to set the correct board definition… If it’s a CubeCell V2 (implied by the 6502 processor), you need to select that board, not the WiFi LoRa 32 V3, which is based on a completely different ESP32-S3 processor…
