1 year ago - You should look at the compile output logs from Arduino and from platform.io - make sure that build_flags includes all the things that get used as build flags by the arduino IDE. I do not think all the build flags that should be there are (this is what I hate about platform IO, as a core developer - I would have to duplicate a whole bunch of logic to blow up every compile attempt that missed any #defines that were required.
and -DIS_AVR128DA28 shouldn't be there - there's already a builtin compiler supplied macro (__AVR_AVR128DB28__ I think), plus I supply a shitload of macros, see Ref_Defines.md. which can be used to identify parts.
- The configuration of PF6 however is completely outside of the realm of what any code running on the AVR can do, the code uploaded has no bearing on it. The function of the reset pin is configured by the fuses, so you need to set it, it's in one of the sysconfig fuses (I forget which of the two or which bits it is) to the correct value) when writing the fuses.

I am trying to get my AVR128DB28 MCU to reset using .. well, the RESET pin (PF6). I'm using the reset circuit https://github.com/SpenceKonde/DxCore/blob/master/megaavr/extras/Ref_Reset.md as conform Spence's advice.
Using the Arduino IDE and the option [Reset pin function: "Hardware Reset (recommended)"] it works like a charm (thanks Spence).
But I'm shifting towards Visual Code and Platformio and I can not get the same code/hardware to reset if the [reset] button is pressed..
This is my platform.ini file:
[platformio] workspace_dir = .pio.nosync default_envs = AVRxDB28 name = testReset description = test Reset circuit
[env] framework = arduino build_unflags =
[env:AVRxDB28] platform = atmelmegaavr board = AVR128DB28 build_flags = -DIS_AVR128DB28 upload_protocol = jtag2updi upload_flags = board_hardware.bod = 2.7v board_hardware.eesave = yes board_hardware.uart = no_bootloader board_hardware.rstpin = reset
This is the (test) code I'm using:
/*------------------------------------------------------
- Chip: "AVR128DB28"
- Clock Speed: "24 MHz internal"
- millis()/micros() timer: |TCB2 (recommended)"
- Reset pin function: "Hardware Reset (recommended)"
- Startup Time: "8ms"
- MultiVoltage I/O (MVIO): "Disabled"
- --
- Programmer: "jtag2updi" -----------------------------------------------------/
//============================================================== void setup() { pinMode(PIN_PA7, OUTPUT); pinMode(PIN_PF6, INPUT_PULLUP);
Serial.begin(115200); Serial.println("\n\n\nAnd than it begins ....");
for (int i=0; i<10; i++) { digitalWrite(PIN_PA7, CHANGE); delay(500); } Serial.println();
} // setup()
//============================================================== void loop() { digitalWrite(PIN_PA7, CHANGE); delay(100); if (!digitalRead(PIN_PF6)) Serial.println("RESET is LOW"); } // loop()
I'm so close but still so far away.
I hope someone can and will help me!
