What Is My Camera’s Firmware

To find the firmware version, put the SD card in a computer somewhere and do this:

$ touch /mnt/cameraSD/ver.req

Basically you need an empty file called ver.req in the top level of the SD card. Put the camera back in and turn on in playback. Hold SET and DISP (in that order). My camera says the following.

Canon PowerShot A590 IS
P-ID:3176 NT D
Firmware Ver GM1.01B
No Error
