Failing to Upload

[bpbarwick]

I am attempting to upload to a TinyS3 using an esp32 Dev Kit and esp version 1.0.6 as stated in this other issue. Arduino IDE is able to compile, but fails to upload with the following error message. This may very well be something I am doing wrong, but I have followed the Material Foundry instructions step by step on two different computers now with the same results.

Arduino: 1.8.19 (Windows 10), Board: "ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None"

Sketch uses 1060246 bytes (80%) of program storage space. Maximum is 1310720 bytes.

Global variables use 51568 bytes (15%) of dynamic memory, leaving 276112 bytes for local variables. Maximum is 327680 bytes.

Hey, as I mentioned in the other issue, the current DIY firmware does not work on an esp32-s3 (which the TinyS3 is). Simply setting the board to an esp32 devkit won't work, because you don't have an esp32 devkit connected and during the firmware upload the software notices this. What the other person did was buy an esp32 devkit. You could do the same, or wait until I have made the latest firmware version (currently only for the production sensor) available for the DIY sensor. If you decide to buy another board, please double check that it is actually an esp32 board, and not some variant (such as the esp32-s2, esp32-s3, esp32-c2, etc). You might have to look at the product details, not just the product name. For example, the Arduino Nano Esp32 is actually an esp32-s3.

Thanks for the explanation and sorry for my stupidity! I guess I had just scanned over that other issue and missed that key point. I appreciate your timely response.
