Arduino IDE Sketch size too large
Closed this issue · 5 comments
Have tried several examples with the 2.8" TTGO T-RGB display using the settings recommended in the README. I always get a similar warning message to:
Sketch uses 511393 bytes (16%) of program storage space. Maximum is 3145728 bytes.
Global variables use 22340 bytes (6%) of dynamic memory, leaving 305340 bytes for local variables. Maximum is 327680 bytes.
Bytes for each example are different but all exceed 3145728.
Final output:

Correction, the file size is within limits. To address the No serial data received error:
- Unplug USB-C cable
- Press & hold boot button (labeled BOT)
- Reinsert USB-C cable
- Run upload from Arduino IDE
Output terminal now reports expected:

However, I still always get a blank screen, even after hitting the reset (labelled RST) button or powering off-on.
Write a firmware to test whether the hardware is intact

Thx @lewisxhe. Reseting the firmware didn't work for my 2.8" T-RGB Round device. The backlight comes on, but even the firmware update produces a black screen.
I confirmed the above esptool firmware update process works on a different device. So I suspect it's a hardware issue at this point.
