Description

Wrong FQBN in compiler output

Compiling a sketch in Arduino IDE v2.3.2 for target "M5Core2" prints the FQBN as esp32:esp32:m5stack_core2 in the log output.

The correct FQBN (as reported by arduino-cli v0.35.3 and proved to be valid in GitHub CI action) is esp32:esp32:m5stack-core2

(Dash instead of underscore.)

Espressif ESP32 package v2.0.14 was used in both cases!

Inconsistent define ARDUINO_M5STACK_CORE2 vs. ARDUINO_M5STACK_Core2

Observed when compiling a sketch in Arduino IDE v2.3.2 or with arduino-cli v0.35.3, respectively, for target "M5Core2" (both using Espressif ESP32 package v2.0.14): In one environment, the compiler flag was set as -DARDUINO_M5STACK_CORE2, in the other one as ARDUINO_M5STACK_Core2. Since preprocessor directives like #if defined(ARDUINO_M5STACK_CORE2) are case sensitive, both variants had to be considered in the source code.

Sketch

#if defined(ARDUINO_M5STACK_CORE2) || defined(ARDUINO_M5STACK_Core2)
    // Note: Depending on the environment, either variant is used!
    #pragma message("ARDUINO_M5STACK_CORE2 defined; assuming M5Stack Module LoRa868 will be used")
    #define USE_SX1276
#endif

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

• I confirm I have checked existing issues, online documentation and Troubleshooting guide.

The variant is never called out with a dash, and variant names should always get upcased. If arduino-cli is changing that, then that is something on the arduino side.

[me-no-dev]

if you get different results with the same code here, but different apps, then issue must be in the apps. Really surprising to see such change though.

Your FQBNs start with esp32 which means that you are installing from Git. Are you sure you are on the correct version?

[matthias-bs]

Yes, I double-checked the version.

The variant is never called out with a dash, and variant names should always get upcased. If arduino-cli is changing that, then that is something on the arduino side.

How about the FQBNs esp32:esp32:ttgo-lora32:Revision=TTGO_LoRa32_V1, esp32:esp32:ttgo-lora32:Revision=TTGO_LoRa32_V2, esp32:esp32:ttgo-lora32:Revision=TTGO_LoRa32_v21new? The variants have dashes.

The defines are ARDUINO_TTGO_LoRa32_V1, ARDUINO_TTGO_LoRa32_V2 and ARDUINO_TTGO_LoRa32_v21new, respectively.

I didn't encounter any problems with those in the same setups.

Please explain in better detail what the difference is between the build environments. The relevant information comes from the boards.txt files, which look like the following in current master. Please check the files on your build machines.

ttgo-lora32.menu.Revision.TTGO_LoRa32_V2.build.board=TTGO_LoRa32_V2

Okay, the boards.txt files have the same version, but are different...

Local installation (Arduino IDE):

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

Github:

echo "index-url=--additional-urls https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json" >> $GITHUB_OUTPUT

I can't see any difference in there... Weird!

For better maintenance, M5 group has changed the files on you :)
#9086
The file tagged in 2.0.14 shows build.board=M5STACK_Core2. Current master is M5STACK_CORE2. You decide which you think is right...

Okay - the definitions in the board.txt file have been changed while the board package version still remains the same (v2.0.14).
I didn't expect that!
