Then it hangs forever.

Likely this is becuase

1. The wrong dfu-util version is used, it really really needs that one referenced in https://downloads.arduino.cc/packages/package_index.json ("version": "0.11.0-arduino5", "name": "dfu-util"). PlatformIO built in one has problems on some systems (maxgerhardt/platform-renesas-old-dontuse#2)
2. The -s 0x4000:leave syntax does not work (with the one from the Arduino IDE)
3. -Q flag is not given for final reset (like Arduino IDE does)

Intellisense issue on some systems

Per maxgerhardt/platform-renesas-old-dontuse#1 (comment).

Magically on this user's system, the c_cpp_properties.json gets wrongly generated with missing path seperator character:
On my old platform:

On this current-version version platform:

 "compilerArgs": [ "-mcpu=cortex-m4", "-mfloat-abi=hard", "-mfpu=fpv4-sp-d16", "-mthumb", "-iprefixC:Users94837.platformiopackagesframework-arduinorenesas-uno", "@C:Users94837.platformiopackagesframework-arduinorenesas-unovariantsUNOWIFIR4includes.txt", "" ]

I have no idea how that's possible since it does work on my Windows 10, x64, system:

            "compilerPath": "C:/Users/Max/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-gcc.exe",
            "compilerArgs": [
                "-mcpu=cortex-m4",
                "-mfloat-abi=hard",
                "-mfpu=fpv4-sp-d16",
                "-mthumb",
                "-iprefixC:/Users/Max/.platformio/packages/framework-arduinorenesas-uno",
                "@C:/Users/Max/.platformio/packages/framework-arduinorenesas-uno/variants/UNOWIFIR4/includes.txt",
                ""
            ]

I pushed a countermeasure for this, that is, in the __idedata phase, don't return -iprefix <prefx> @<file>, but actually expand out all include paths: https://github.com/maxgerhardt/platform-renesas/blob/bc8d2f1ae4d0a8507dbee06861a884293c0d83a2/builder/frameworks/arduino/mbed-core/arduino-core-mbed.py#L157-L179

According to the user, the problem remained present even after reinstalling everything and trying it on a different computer. Might be issues with specific character encoding sets, e.g. Chinese? I have no idea real idea though. They had the exact same VSCode version, C/C++ extension version, PlatformIO core and PlatformIO extension version as me.

`ARDUINO_ARCH_RENESAS_UNO` is not defined

The original Arduino core defines ARDUINO_ARCH_{build.arch}, which leads to ARDUINO_ARCH_RENESAS_UNO being defined:

-DARDUINO=10607 -DARDUINO_UNOWIFIR4 -DARDUINO_ARCH_RENESAS_UNO -DARDUINO_ARCH_RENESAS -DARDUINO_FSP -D_XOPEN_SOURCE

In PlatformIO, this definition is missing:

-DPLATFORMIO=60110 -DARDUINO_UNOWIFIR4 -DARDUINO_UNOR4_WIFI -DNO_USB -DBACKTRACE_SUPPORT -DLWIP_DNS=1 -DCFG_TUSB_MCU=OPT_MCU_RAXXX -DNO_OTA_NETWORK -D_RA_CORE=CM4 -D_RENESAS_RA_ -DARDUINO=10810 -DARDUINO_ARCH_RENESAS -DARDUINO_FSP -D_XOPEN_SOURCE

This is already in use by some libraries and code examples: https://github.com/search?q=ARDUINO_ARCH_RENESAS_UNO&type=code

Missing identifier board macro for Uno R4 Minima

When board = uno_r4_minima is selected.

Related to #3, the board identifying macros are missing, which for the Arduino R4 Minima is ARDUINO_MINIMA.

Simple sketch using LED matrix doesn't work. void loop() is never called

Hello,

I tried to write some code on Arduino UNO R4 WiFi and it desn't work. I was debugging code and it seems that after enabling timer irq it is invoked all the time so program cannot go to loop function. But I'm not sure that is the case here.

code:

#include <Arduino.h>
#include <Arduino_LED_Matrix.h>

ArduinoLEDMatrix matrix;

uint32_t frame1 [3] =
{
  0,
  0,
  0
};

uint32_t frame2[3] =
{
  UINT32_MAX,
  UINT32_MAX,
  UINT32_MAX
};


void setup() {
  Serial.begin(115200);
  matrix.begin();
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  matrix.loadFrame(frame2);
  digitalWrite(LED_BUILTIN, HIGH);
  delay(1000);
  matrix.loadFrame(frame1);
  digitalWrite(LED_BUILTIN, LOW);
  delay(1000);
}

the same code works fine in newest Arduino IDE 2.2.1

Linking errors with Arduino IoT Cloud

Consider the platformio.ini

platform = renesas-ra
board = portenta_c33

with src/* files from https://github.com/arduino-libraries/ArduinoIoTCloud/tree/1.13.0/examples/ArduinoIoTCloud-Basic.

Compilation will go through, but linking will fail, complaining about double-defined symbols with libnosys.a and the "Storage" library, which also wants to implement _write, _read, et cetera.

While it does compile just fine in the Arduino IDE.

I've recorded the Arduino IDE linker commands here. Noticable differences:

• no --specs=nano.specs in Arduino IDE`, but PIO has it
• missing -nostdlib in PIO during C/C++ files compilation but present during linking
• missing -Wl,--whole-archive -Wl,--start-group [..] -Wl,--no-whole-archive -Wl,--end-group missing in PIO

Trying to patch that in, especially with

env.Prepend(_LIBFLAGS="-Wl,--whole-archive  -Wl,--start-group ")
env.Append(_LIBFLAGS=" -Wl,--no-whole-archive -lfsp -lstdc++ -lsupc++ -lm -lc -lgcc -lnosys -Wl,--end-group ")

in the arduino.py scirpt results.. in diferent kind of linking errors, in lwip.

whatever the case may be, something is causing this to not build correctly in PIO while it does work in the Arduino IDE.

`strnlen` was not declared in this scope

#include <string.h> is in place.

Works after declaring:

size_t strnlen(const char* s, size_t maxlen);

cannot compile with -flto flag

I get build errors as soon as I add -flto to the build flags.

I was also able to reproduce the issue on the arduino-blink example

Just adding

build_flags = -flto

makes the build fail with:

RTC.begin() deadlocks processor

See arduino/ArduinoCore-renesas#88.

The Arduino framework code has a bug / undefined behavior in which the RTClass::begin() function, when compiled by the here used ARM GCC 10.3.1. produces wrong assembly in such a way that it causes an infinite loop at the is_initialized = false statement. Calling RTC.begin(); is a game-over.

Broke a user trying to use an Arduino IoT sketch with the Uno R4 WiFi at https://community.platformio.org/t/cant-connect-to-arduino-iot-cloud-with-platformio/35087.

This either needs a minimal package update with just the patch or (sadly) a downgrade of the compiler version to exactly match the Arduino IDE's behavior (7.0.1). In the last case I cannot however guarantee whether a certain set of compiler / optimization switches also ends up producing the wrong assembly code in 7.0.1.

Upgrade framework-arduinorenesas-uno

https://github.com/arduino/ArduinoCore-renesas/tree/1.0.4 has been recently released, but platform-renesas-ra 1.1.0 is using framework-arduinorenesas-uno in the 1.0.2 version.

Is there a way to override this from the platformio.ini?

Is this even the correct project to report this bug? Where I can I find the definition of framework-arduinorenesas-uno?

Thank you!

Please upgrade framework-arduinorenesas-uno

Arduino has recently released 1.1.0, but the PlatformIO registry still has 1.0.5

https://github.com/arduino/ArduinoCore-renesas/releases/tag/1.1.0

Usage fault when executing code complied with GCC 10 but not with GCC 7

The following example causes a usage fault when built with GCC 10, but reverting back to GCC 7 fixes the problem. The fault occurs when executing the 2nd delay in loop(), or directly thereafter.

#include  < Arduino.h >
#include "Arduino_LED_Matrix.h"

ArduinoLEDMatrix matrix;

This is because the JSON board definition for the Uno R4 WiFi is missing an identifying macro, Obvious give-away:

So -DARDUINO_UNOWIFIR4 is missing in the Uno R4 WiFi's extra_flags.

Build flags missing /wrong from Arduino

What PlatformIO misses:
1: -Os (makes firmware *really big!)
2. -g3
3. -fno-use-cxa-atexit
4. -fno-rtti
5. -fno-exception
6. -nostdlib

What's wrong:

1. -DLWIP_DNS=1 given for Minima. Only used with Uno R4 WiFi
2. Different warning flags?

In the Linking phase, PlatformIO:

arm-none-eabi-g++ -o .pio\build\uno_r4_minima\firmware.elf -T C:\Users\Max.platformio\packages\framework-arduinorenesas-uno\variants\MINIMA\fsp.ld -mcpu=cortex-m4 -mthumb -Wl,--gc-sections --specs=nosys.specs -mfloat-abi=hard -mfpu=fpv4-sp-d16 .pio\build\uno_r4_minima\src\main.cpp.o -L.pio\build\uno_r4_minima -LC:\Users\Max.platformio\packages\framework-arduinorenesas-uno\variants\MINIMA -LC:\Users\Max.platformio\packages\framework-arduinorenesas-uno\variants\MINIMA\libs -Wl,--start-group .pio\build\uno_r4_minima\libFrameworkArduinoVariant.a .pio\build\uno_r4_minima\libFrameworkArduino.a -lfsp -lstdc++ -lsupc++ -lm -lc -lgcc -lnosys -Wl,--end-group

What's missing:

• no .map file generation

In general:

• Arduino IDE uses GCC 7.0.1, PlatformIO uses 10.3.1. May have subtle differences.

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `python -m pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq/index.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

And that's after a clean reinstall of [email protected]. The platform.py logic might no be able to handle the case with the Arduino Uno R4 WiFi which needs tool-bossac to preload but at the same time tool-openocd to open the debug session.
