ESP32-C3 platformio arduino framework run-time error with 2MB flash

I have an ESP32-C3 AI thinker module with 2MB flash. I have used this before with platformio and arduino framework (worked fine about a year ago). But now I get the following run time error complaining about the detected flash size 2MB being smaller than the binary image (4MB). ELF file SHA256: bfb3...

Re: Any issue with ESP-C3 BLE uart and Apple iOS devices ?

Never mind, increasing tx power to 0dB fixed the problem with the specific app (XCDisplay). Another app "Bluefruit LE connect" was able to connect even with the lower tx power.

Any issue with ESP-C3 BLE uart and Apple iOS devices ?

I've been using a third party app on my Samsung Android phone to connect to my ESP32-C3 via BLE uart interface, and have no problem receiving data packets sent at 100mS intervals. But a friend reports that he has not been able to connect with his iOS devices (phone, tablet). The BLE server is not vi...

Re: ESP32-C3 + LittleFs + USB serial/jtag issues

Accidentally found a platform and packages specification that works :-) Now LittleFS, Preferences and USB CDC on boot are working ... Keeping my fingers crossed.

Re: esp32-C3 usb serial/jtag for flashing AND serial console output

You don't need all the extra, just the define flags: CODE: SELECT ALL -DARDUINO_USB_MODE=1 -DARDUINO_USB_CDC_ON_BOOT=1 Thanks for the response guys, this was all that was needed for the C3. My test code : #include <Arduino.h> uint32_t chipId = 0; void setup() { Serial.begin(); } void loop() { for(i...

esp32-C3 usb serial/jtag for flashing AND serial console output

I'm using PlatformIO with Arduino framework in Visual Studio Code on Ubuntu 22.04. I'm able to flash my ESP32-C3 module using the built-in serial/jtag module (it shows up as /dev/ttyACMx) while monitoring serial debug prints on the uart0 pins (with usb-uart adapter, appears as /dev/ttyUSBx). However...

Re: ESP32-C3-DevKitM-1 SHA-256 comparison failed

I saw the same issue with an AI Thinker ESP32-C3M module with 4MB flash, when I hooked it up to test, the factory flash content booted fine, but when I flashed some test code, saw this message. The code worked fine as far as I could tell :-). This was a couple of months ago. I just checked another A...
