I’ve been using PlatformIO for some time and successfully used it to create projects based on ESP8266 and ESP32. Not long ago, I did some initial work on a project using LilyGo T-Display (not S3) and that works fine. More recently, however, I’ve obtained a T-Display S3 board and am having real trouble getting the code to upload - I’ve never managed to do this yet with PlatformIO. I’ve even completely removed and reinstalled VSC and PIO to make sure I’m running the latest and greatest. In desperation, I tried uploading a sketch using the Arduino IDE - this works perfectly (as long as I put the chip in Boot mode), so I know the hardware is working OK.
In PIO, I get the failure shown below with the chip in run mode. If I put it into Boot mode, the output stops after detecting COM6 - nothing else happens until I disconnect the ESP32 S3.
This is on a Win11 system with all updates. PIO is using esptool.py 4.4, Arduino IDE is using esptool.exe 4.2.1. I tried replacing esptool.py with v4.2.1 but PIO simply overwrote it with v4.4. I also tried putting ‘platform_packages = tool-esptoolpy@4.2.1’ in platformio.ini but it couldn’t find that version.
I’m stuck and hope someone can give me a pointer or two as to what to try next.
