# avrdude - how to only write to device?

I've been using the avrdude for quite some time to burn my atmega mcu's. The read / write operations are fast if the code is small in size but it gets a lot slower as the code base grows.

I've noticed that avrdude not only writes from the mcu but also reads the on-chip data. I wasn't able to find anything regarding the issue in man avrdude.

Is it even possible to only write using avrdude?

• Option -V (capital V, not lowercase v) disables verify. (default is to verify after write.) – MarkU Jun 5 '17 at 9:54

According to AVRDUDE documentation, 2.1 Option Descriptions, the command-line option "-V" disables automatic verify check when uploading data.
