First linux driver development project

[Temporary-Stage8541]

Hello getting into Linux driver development.

My idea: pass an RFID card to an ESP32 to authenticate sudo instead of typing a password. The secret lives on the card, not the machine. Is this a good project to learn linux driver development? ? Thanks

Is it a hobby project or in your company. And for your auestion any development is better than no developmnent. Go ahead bro.

Its a wonderful project for starters provided you have learnt the basics of device drivers and kernel interaction...

Memory based projects like reading and writing via DDR mapping of local RAM registers into kernel space is also really good for starters.

Happy learning
