Re: Counting data downloaded and uploaded on RPi4...

Thank you for your reply.

I don't think it is 32 bit limitation. I have a router based on OpenWRT. It has "MediaTek MT7621" CPU which is 32Bit. The same files there shows values even over 1TB transferred.

Sorry guys but i am little lost...

On

Code: Select all

https://www.raspberrypi.org/documentation/raspbian/applications/vcgencmd.md
we can read that:

Code: Select all

"Displays the build date and version of the firmware on the VideoCore"
In my understanding
