Boot/config.txt write access issue

[jorgevete]

Hi all how are you ?

Im trying to change a HDMI configuration on the file /boot/config.txt , but when I try to save it I get that the file is read only.

I have tried with sudo vi /boot/config.txt but same issue.

What Im missing ?

Thanks for your help !!
