I’ve been trying different things and keep getting this error. Is it possible I have a bad board? I first tried it on RPi with two different cables and every possible upload speed. Then tried windows with three different cables and all different speeds. Here’s the full error msg. The sketch is the basic blink from the hookup guide. The board the ESP32 micromod is plugged into is the weather board. The error has been very consistent on both platforms and the hex code has not changed.
Arduino: 1.8.13 (Windows 10), Board: “SparkFun ESP32 MicroMod, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None”
