I'm sure there is something I'm not doing properly. I have an ESP32-S3 DevkitC1 (real expressif, not a knockoff) and loaded an existing project I have been using on a gen1 ESP32 via USB. I had to use the enable/boot buttons to get the first project to load, I can install new projects via RTS pin reset now, that part works great.
The issue is I wasn't greeted by the expected serial debugging information from my project.
I know my project sketch works because it's working and I can connect to it over the network and the hardware attached to the ESP is working properly.
I checked baud rate and ports etc. To eliminate all variables as there are some libraries in my project sketch, I made a very simple serial printing sketch, uploaded that and am seeing nothing on serial monitor on the USB port. This is the test sketch that fails:
void setup() {
// put your setup code here, to run once:
delay(500);
Serial.begin(115200);
}
void loop() {
// put your main code here, to run repeatedly:
delay(500);
Serial.println("foop");
delay(500);
Serial.println("woop");
}
Yes, serial monitor is set for 115200, I am using the "USB" port on the dev board. I tried the JTAG port, no luck. I even hooked up a FDDI type adapter to the RX/TX pins to see if the serial messages were being sent over that, no luck there.
I am able to upload via USB and I get the following line on boot via USB so I believe my hardware and USB setup is good:
ESP-ROM:esp32s3-20210327
I feel like I am doing something incredibly dumb or there is something I fundamentally don't understand about the newer boards.
Arduino IDE is version 1.8.19 and ESP32 board package 2.0.4, on mac OS Monterey.
Thanks in advance for any assistance.
