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!
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;
void setup() {
Serial.begin(115200);
matrix.begin();
}
const uint32_t happy[] = {

};
const uint32_t heart[] = {

0x44042081,
0x100a0040
};
void loop(){
matrix.loadFrame(happy);

While it does compile just fine in the Arduino IDE.
I've recorded the Arduino IDE linker commands here. Noticable differences:
--specs=nano.specs
in Arduino IDE`, but PIO has it-nostdlib
in PIO during C/C++ files compilation but present during linking-Wl,--whole-archive -Wl,--start-group [..] -Wl,--no-whole-archive -Wl,--end-group
missing in PIOTrying 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.

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

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.
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:

Thank you
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.
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

============================================================
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.

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.

Everything is the same as the arduino-uno-r4-led-animation
example.
Upon running the usual: pio run && pio run --target upload
, it looks like everything uploaded successfully. but it just flashes (removes all the current code running (sorry if I'm not using the right terminology, I'm a computer science major and I'm trying to learn electrical engineering just for fun, as a hobby)). And I'm running what I think is right, and this is the output:

0 lights come on, nothing happens, even if I do a Serial.println("test");

or setup()
, it doesn't do anything after checking serial monitor?
For literally output or any changes other then flashing? I'm confused?
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
#include <string.h>
is in place.
Works after declaring:
size_t strnlen(const char* s, size_t maxlen);
Please would you consider adding support for the new WeAct Studio RA4M1 board:
