I want to load the arduino uno Rev3 boot loader to my 328P chip. I am using USB ASP and Extreme Burner.
I looked at arduino installation folder and there are several Hex files available under "C:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders\atmega". I guess I need to make use of ATmegaBOOT_168_atmega328.hex file as the name suggests. Also I understand that the fuse bit I need to select is efuse-0x05 hfuse-0xD6 and lfuse - 0xFF
Can anyone confirm this? Are there any other latest Hex files available?
You want the file: optiboot_atmega328.hex
It is in the optiboot folder under bootloaders.
The normal fuses are:
low: FF
high: DE
extended: 05
Optiboot is the 512 byte bootloader, normally installed on the Uno chips.
As you can see from the datasheet, a high fuse of DE gives a bootloader size of 256 words (that is, 512 bytes).
And the relevant entry in the boards.txt file for the Uno (the standard fuses when you burn the bootloader):
uno.name=Arduino Uno
uno.upload.protocol=arduino
uno.upload.maximum_size=32256
uno.upload.speed=115200
uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
uno.bootloader.path=optiboot
uno.bootloader.file=optiboot_atmega328.hex
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.build.mcu=atmega328p
uno.build.f_cpu=16000000L
uno.build.core=arduino
uno.build.variant=standard
This confirms my suggested fuse settings.

After I used VSCode (current version 1.61.0) and the Arduino IDE (1.8.13 / 1.8.16 - WIndows installer version) for about a year on two Windows 10 devices both devices stopped showing available Arduino / ESP8266 board types yesterday.
The Arduino board configuration only shows one item "Selected Board:" with an empty drop down.
The Arduino IDE on both devices still works (Tools - Boards show the familiar collection of boards)
My settings (searched for Arduino) are
{
"arduino.path": "C:\\Program Files (x86)\\Arduino"
}
on both devices - I have not changed this since the setup about a year ago and the Arduino IDE is still there und my c-drive.
What else can I check or what settings might lead to an empty board selector?
Its a bug in v0.4.6 of vscode arduino extention. Roll back to v0.4.5 and before, Works fine.
Same problem here. I think its a bug in the vscode extension. My workaround is to manually set the Bord type in the .vscode/arduino.json file. Simply add the
"board": "arduino:avr:uno", line to your json and it will work.
{
"port": "COM5",
"board": "arduino:avr:uno",
"sketch": "example.ino"
}
First you need to install the board you need from:
View / Command Palette / Arduino: Board Manager
Then you can select your board from:
View / Command Palette / Arduino: Board Configuration
I am having some issues with the Send Data with Sound Project on Arduino. I have my Arduino nano BLE sense, ChirpSDK by Asio Ltd Version 3.4.0 installed, I put in the CHIRP_APP_KEY, CHIRP_APP_SECRET, CHIRP_APP_CONFIG from the chirp website, and I also have the Arduino nano BLE board selected when uploading the code. But for some reason I keep getting this error below:
ChirpColor:22:10: error: chirp_connect.h: No such file or directory
#include "chirp_connect.h"
^~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1
chirp_connect.h: No such file or directory
Any help would be very much appreciated, thanks.
The SDK functions have been renamed in the latest release. So connect is replaced with sdk.
With the latest version, you need to
#include "chirp_sdk.h"
See the latest header file for the function declarations - https://github.com/chirp/chirp-arduino/blob/develop/src/chirp_sdk.h
I wanted to upload Arduino sketches to my RaspberryPi 3+ b so I downloaded the RasPiArduino folder from me-no-dev and so on but at the end it gave me this error: Error compiling for board RaspberryPi B+/2
How can I make my Pi 3 usable for Arduino?
I am using the excellent http://platformio.org/ together with Visual Studio Code to develop for Teensy 3.6 (an Arduino compatible board).
This works great. But I wanted to do better debugging via SWD (serial wire debug).
So I disconnected the Arduino-compatible USB-chip and connected via SWD and JLINK instead. Similar to this: https://mcuoneclipse.com/2017/04/29/modifying-the-teensy-3-5-and-3-6-for-arm-swd-debugging/
I can flash firmware that I built via platformio using the "J-Link Lite" software just fine. Also I can run the J-Link GDB Server without a problem.
But I can't get the IDE integration to work.
My platformio.ini looks like this:
[env:teensy36]
platform = teensy
board = teensy36
framework = arduino
upload_protocol = jlink
debug_tool = jlink
Still the upload_protocol is ignored and when I invoke upload (platformio.exe run --target upload) via the IDE all I get is
Linking .pioenvs\teensy36\firmware.elf
Checking program size
text data bss dec hex filename
17348 172 2696 20216 4ef8 .pioenvs\teensy36\firmware.elf
Building .pioenvs\teensy36\firmware.hex
Uploading .pioenvs\teensy36\firmware.hex
Teensy Loader, Command Line, Version 2.1
Read ".pioenvs\teensy36\firmware.hex": 17520 bytes, 1.7% usage
Soft reboot is not implemented for Win32
Waiting for Teensy device...
(hint: press the reset button)
So it's still trying to upload via Arduino compatible USB connection instead of via SWD connection. How can I get platformio to change the upload method or upload_protocol?
From Project Configuration File platformio.ini, it provides an example of how to configure Jlink GDB server:
[env:bluepill_f103c8]
...
; Debug options
debug_tool = custom
debug_server =
JLinkGDBServer
-singlerun
-if
SWD
-select
USB
-port
2331
-device
STM32F103C8
If JLinkGDBServer.exe is not included in PATH, then you need to specify the full file name of JLinkGDBServer.exe.
I have tried this, it works.
There is another example of using JlinkGDBServerCL.exe - J-Link and ST Nucleo.
I am new in arduino and I am trying to update the firmware in my Arduino WiFi shield but I am facing some problems. I did exactly what the instructions said about the update(MacPorts, dfu-programmer, jumper) but when I am trying to run the installation there were some problems that I cannot find out. I haven't change anything in the script, and I really don't know what is going on.
Any help it will be great!!! That's exactly what I get. The problem is in lines 55, 56, 57.
Arduino WiFi Shield upgrade
Disclaimer: to access to the USB devices correctly, the dfu-programmer needs to be used as root. Run this script as root.
ArduinoWifiShield_upgrade_mac.sh: line 55: cd: /Applications/Arduino.app/Contents/Java/hardware/arduino/avr/firmwares/wifishield/scripts/hardware/tools/avr/bin: No such file or directory

Error opening the file.
Something went wrong with creating the memory image.
Done. Remove the J3 jumper and press the RESET button on the shield.
Thank you!
Thank you very much in advance.
