Programming Methods:¶

-dprog=<method>

Target Device Selection:¶

-dpart=part

Set target abbreviated name or number. For some programmers, if -dpart is not given programmer's supported devices are listed. Set -dpart=auto for auto-select. Auto-select does not work with all programmers, so it is recommended to always specify a target device explicitly.

Parallel Device Settings:¶

-dlpt=address|device name

specify device name (Linux ppdev, FreeBSD ppi, serial) or direct I/O parallel port address (0x378, 0x278, 0x3BC)

-dno-poll

Program without data polling (a little slower)

-dno-retry

Disable retries of program enable command

-dvoltage=value

Set timing specs according to the power supply voltage in [V] (default 3.0)

-dt_sck=time

Set minimum SCK high/low time in micro-seconds (default 5)

-dt_wd_flash=time

Set FLASH maximum write delay time in micro-seconds

-dt_wd_eeprom=time

Set EEPROM maximum write delay time in micro-seconds

-dt_reset=time

Set reset inactive (high) time in micro-seconds

-dinvert=[sck[,mosi[,miso[,reset]]]]]

Invert specified lines Use -v=3 option to see current settings.

-d89

Allow parallel programming of AT89S51 and AT89S52 devices.

Atmel Low Cost Programmer Serial Device Settings:¶

-dserial=device name

Set serial interface as /dev/ttyS* (default /dev/avr)

-dspeed=1200|2400|4800|9600|19200|38400|57600|115200

Set speed of the serial interface (default 19200)

Stk500 specific options:¶

-dhiv

Use Hi-V programming instead of SPI (default is SPI).

--rd_aref

Read the ARef Voltage. Note that due to a bug in the stk500 firmware, the read value is sometimes off by 0.1 from the actual value measured with a volt meter.

--wr_aref=value

Set the ARef Voltage. Valid values are 0.0 to 6.0 volts in 0.1 volt increments. Value can not be larger than the VTarget value.

--rd_vtg

Read the Vtarget Voltage. Note that due to a bug in the stk500 firmware, the read value is sometimes off by 0.1 from the actual value measured with a volt meter.

--wr_vtg=value

Set the VTarget Voltage. Valid values are 0.0 to 6.0 volts in 0.1 volt increments. Value can not be smaller than the ARef value.

--rd_osc

Read the oscillator frequency in Hertz.

--wr_osc=value

Set the oscillator frequency in Hertz, from 14.06 to 3686400.

Functions:¶

--upload

Upload "input_file" to the AVR memory.

--verify

Verify "input_file" (processed after the --upload opt.)

--download

Download AVR memory to "output_file" or stdout.

--erase

Erase device.

--segment=flash|eeprom|fuse

Set active segment (auto-select for AVA Motorola output)

Fuse/Lock Bit Operations:¶

--rd_fuses

Read all fuses and print values to stdout

--wr_fuse_l=byte

Write fuse low byte

--wr_fuse_h=byte

Write fuse high byte

--wr_fuse_e=byte

Write fuse extended byte

--wr_lock=byte

Write lock bits. Argument is a byte where each bit is:
Bit5 -> blb12
Bit4 -> blb11
Bit3 -> blb02
Bit2 -> blb01
Bit1 -> lb2
Bit0 -> lb1

--lock

Write lock bits [old method; deprecated].

Files:¶

if=filename

Input file for the --upload and --verify functions in Motorola S-records (S1 or S2) or 16 bit Intel format

of=filename

Output file for the --download function in Motorola S-records format, default is standard output

Other Options:¶

-v=level

Set verbose level (-v equals -v=2, min/max: 0/4, default 1)

--hash=perbytes

Print hash (default is 32 bytes)

--help -h

Help

--version

Print version information

--terminal

Invoke shell-like terminal
