Go to the first, previous, next, last section, table of contents.
The following commands are implemented:
dump memtype addr nbytes
-
Read nbytes from the specified memory area, and display them in
the usual hexadecimal and ASCII form.
dump
-
Continue dumping the memory contents for another nbytes where the
previous dump command left off.
write memtype addr byte1 ... byteN
-
Manually program the respective memory cells, starting at address addr,
using the values byte1 through byteN. This feature is not
implemented for bank-addressed memories such as the flash memory of
ATMega devices.
erase
-
Perform a chip erase.
send b1 b2 b3 b4
-
Send raw instruction codes to the AVR device. If you need access to a
feature of an AVR part that is not directly supported by AVRDUDE, this
command allows you to use it, even though AVRDUDE does not implement the
command.
sig
-
Display the device signature bytes.
part
-
Display the current part settings.
?
-
help
-
Give a short on-line summary of the available commands.
quit
-
Leave terminal mode and thus AVRDUDE.
In addition, the following commands are supported on the STK500
programmer:
vtarg voltage
-
Set the target's supply voltage to voltage Volts.
varef voltage
-
Set the adjustable voltage source to voltage Volts.
This voltage is normally used to drive the target's
Aref input on the STK500.
fosc freq[M|k]
-
Set the master oscillator to freq Hz.
An optional trailing letter M
multiplies by 1E6, a trailing letter k by 1E3.
fosc off
-
Turn the master oscillator off.
sck period
-
Set the SCK clock period to period microseconds.
parms
-
Display the current voltage and master oscillator parameters.
