Atmel AVR

Configuration:platform = atmelavr

Atmel AVR 8-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Optimized to speed time to market-and easily adapt to new ones-they are based on the industry’s most code-efficient architecture for C and assembly programming

Configuration

Upload using Programmer

In the case of external programmers, it’s easy to brick a board simply by specifying incorrect upload flags. It’s highly recommended to use the upload_command option that gives the full control over flags used for uploading.

Note

The list of supported programmers available in avrdude is accessible via the avrdude -c ? command

Upload EEPROM data

To upload EEPROM data (from EEMEM directive) you need to use uploadeep target instead upload for pio run --target command. For example, pio run -t uploadeep.

Fuses programming

PlatformIO has a built-in target called fuses for setting fuse bits. The default fuse bits are predefined in the board manifest file in the fuses section. For example, fuses section for Arduino Uno board. To set fuse bits you need to use target fuses with pio run --target command.

Custom fuses

Custom fuse values and upload flags (based on upload protocol) should be specified in “platformio.ini” (Project Configuration File). The lfuse and hfuse bits are mandatory, efuse is optional and not supported by all targets. An example of setting custom fuses for uno board:

[env:custom_fuses]
platform = atmelavr
framework = arduino
board = uno
upload_protocol = stk500v1
upload_speed = 19200
board_fuses.lfuse = 0xAA
board_fuses.hfuse = 0xBB
board_fuses.efuse = 0xCC
upload_flags =
    -PCOM15
    -b$UPLOAD_SPEED
    -e

MiniCore, MegaCore, MightyCore, MajorCore and MicroCore

MiniCore, MegaCore, MightyCore, MajorCore and MicroCore support dynamic fuses generation. Generated values are based on the following parameters:

Parameter Description Default value
board_build.f_cpu Specifies the clock frequencies in Hz. Used to determine what oscillator option to choose. A capital L has to be added to the end of the frequency number. 16000000L
board_hardware.oscillator Specifies which oscillator is used internal or external. Internal oscillator only works with f_cpu values 8000000L and 1000000L external
board_hardware.uart Specifies the hardware UART port used for serial upload. can be uart0, uart1, uart2 or uart3 depending on the target. Use no_bootloader if you’re not using a bootloader for serial upload. uart0
board_hardware.bod Specifies the hardware brown-out detection. Use disabled to disable brown-out detection. 2.7v
board_hardware.eesave Specifies if the EEPROM memory should be retained when uploading using a programmer. Use no to disable yes
board_hardware.ckout Enables system clock output on targets that have this feature. The system clock will be output on a dedicated output pin. See the target datasheet for more information. Use Yes to enable no
board_hardware.jtagen Enables the JTAG programming and debugging interface for targets that supports JTAG. Use Yes to enable no
board_hardware.cfd Enables clock failure detection. Note that this feature is only available on ATmega324PB and ATmega328PB. Use Yes to enable CFD no

Valid BOD values:

ATmega8, ATmega8515, ATmega8535/16/32, ATmega64/128 AT90CAN32/64/128 Other targets
4.0v 4.1v 4.3v
2.7v 4.0v 2.7v
disabled 3.9v 1.8v
  3.8v disabled
  2.7v  
  2.6v  
  2.5v  
  disabled  

Hardware configuration example:

[env:custom_fuses]
platform = atmelavr
framework = arduino
board = ATmega32

board_build.f_cpu = 1000000L
board_hardware.uart = uart0
board_hardware.oscillator = internal
board_hardware.bod = 2.7v
board_hardware.eesave = no

upload_protocol = usbasp
upload_flags =
  -Pusb

Overriding default fuses command

PlatformIO splits the command for programming fuses in the following overridable parts:

Variable Description Examples
FUSESUPLOADER The tool used for setting fuses By default avrdude is used
FUSESUPLOADERFLAGS General command-line options that control uploader’s behavior -D, -V, -P COM1, -C atmelice_isp, -b 115200
FUSESFLAGS A list of flags specific to fuses settings -Ulock:w:0x2F:m, -Uefuse:w:0xCB:m, -Ulfuse:w:0xFF:m
SETFUSESCMD Variable that holds the final command compiled from variables above $FUSESUPLOADER $FUSESUPLOADERFLAGS $UPLOAD_FLAGS $FUSESFLAGS

If for any reason default parameters are not suitable for your project, you can override the entire upload command or any particular part of that command using an extra script, for example, you can override only fuses values:

Import("env")

env.Replace(
    FUSESFLAGS=[
        "-Uhfuse:w:0xAA:m",
        "-Uefuse:w:0xBB:m",
        "-Ulfuse:w:0xCC:m",
        "-Ulock:w:0xDD:m"
    ]
)

Or override a specific uploader flag:

Import("env")

env.Append(
    FUSESUPLOADERFLAGS=[
        "-V",
        "-D"
    ]
)

It’s also possible to completely override the entire upload command:

Import("env")

env.Replace(
    FUSESUPLOADERFLAGS=[
        # use "tool-avrdude-megaavr" for the atmelmegaavr platform
        "-C", "$PROJECT_PACKAGES_DIR/tool-avrdude/avrdude.conf",
        "-p", "$BOARD_MCU",
        "-c", "atmelice_isp",
        "-e", "-v"
    ],
    SETFUSESCMD="avrdude $FUSESUPLOADERFLAGS -Ulock:w:0x0F:m",
)

Bootloader programming

PlatformIO has a built-in target called bootloader for flashing bootloaders. The default bootloader image and corresponding fuse bits are predefined in the board manifest file in the bootloader section, for example, Arduino Uno. To upload a bootloader image you need to use target bootloader with pio run --target command.

Custom bootloader

Custom bootloader and accompanying fuses should be specified in “platformio.ini” (Project Configuration File). If lock_bits and unlock_bits are not set then the default values 0x0F and 0x3F are used accordingly. An example of setting custom bootloader for uno board:

[env:uno]
platform = atmelavr
framework = arduino
board = uno

board_bootloader.file = /path/to/custom/bootloader.hex
board_bootloader.lfuse = 0xFF
board_bootloader.hfuse = 0xDE
board_bootloader.efuse = 0xFD
board_bootloader.lock_bits = 0x0F
board_bootloader.unlock_bits = 0x3F

MiniCore, MegaCore, MightyCore and MajorCore have a wide variety of precompiled bootloaders. Bootloader binaries are dynamically selected according to the hardware parameters f_cpu, oscillator, uart and upload_speed. For a complete table with all available baud rates, see the Optiboot flash repo. Here is a table with recommended baud rates for different clock frequencies:

Frequency Oscillator type Recommended upload speed
20000000L external 115200
18432000L external 115200
16000000L external 115200
14745600L external 115200
12000000L external 57600
11059200L external 115200
8000000L external/internal 57600/38400
7372800L external 115200
4000000L external 9600
3686400L external 115200
2000000L external 9600
1843200L external 115200
1000000L external/internal 9600

Overriding default bootloader command

PlatformIO splits the command for programming bootloader in the following overridable parts:

Variable Description Examples
BOOTUPLOADER The tool used for programming bootloader image By default avrdude is used
BOOTUPLOADERFLAGS General command-line options that control uploader’s behavior -D, -V, -P COM1, -C atmelice_isp, -b 115200
BOOTFLAGS A list of flags specific to bootloader settings -Uflash:w:/path/to/bootlader_image:i, -Ulock:w:0x2F:m
UPLOADBOOTCMD Variable that holds the final command compiled from variables above $BOOTUPLOADER $BOOTUPLOADERFLAGS $UPLOAD_FLAGS $BOOTFLAGS

If for any reason default parameters are not suitable for your project, you can override the entire upload command or any particular part of that command using an extra script, for example, you can override only fuses values:

Import("env")

bootloader_path = "/path/to/custom/bootloader.hex"

env.Replace(
    BOOTFLAGS=[
        "-Uflash:w:%s:i" % bootloader_path,
        "-Ulock:w:0xFF:m"
    ]
)

Or override a specific uploader flag:

Import("env")

env.Append(
    BOOTUPLOADERFLAGS=[
        "-e", "-p", "/dev/cu.usbserial-1414302"
    ]
)

It’s also possible to completely override the entire upload command:

Import("env")

env.Replace(
    BOOTUPLOADERFLAGS=[
        # use "tool-avrdude-megaavr" for the atmelmegaavr platform
        "-C", "$PROJECT_PACKAGES_DIR/tool-avrdude/avrdude.conf",
        "-p", "$BOARD_MCU",
        "-c", "atmelice_isp"
    ],
    UPLOADBOOTCMD="avrdude $BOOTUPLOADERFLAGS -Ulock:w:0x0F:m",
)
