tools/test-avrdude -b generates an output for which benchmark tables can be filtered. For example,

tools/test-avrdude -b -d 0 \
 -p "-c urclock -P COM20 -p ATmega328P -b 2000000" \
 -p "-c urclock -P COM20 -p ATmega328P -b 1000000" \
 -p "-c urclock -P COM20 -p ATmega328P -b 500000" \
 -p "-c urclock -P COM20 -p ATmega328P -b 250000" \
 -p "-c urclock -P COM20 -p ATmega328P -b 115200" >/tmp/benchmarks

grep '^|' /tmp/benchmarks

to see just the table

Results

The benchmark shows the wall clock time of avrdude carrying out the following tasks

  • Fl-ewv: erase flash, then write a sketch with three sections separated by holes to flash and verify
  • Fl-r: read the full flash memory and write to file
  • EE-wv: write data with two data sections separated by a hole to EEPROM and verify
  • EE-r: read the full EEPROM memory and write to file

The sketch and data payload is roughly one sixth of the respective memory size
