I. Introduction to the environment
Raspberry PI 4B: Runs on the default official 32-bit system.
Second, expand system capacity
When the raspberry PI system starts by default, the raspberry PI does not expand the entire storage space into the entire card by default. If the entire SD card needs to be used, the storage space can be manually expanded into the entire card.
(1) Open raspberry PI command line terminal and enter:
pi@raspberrypi:~ $ sudo raspi-config
Copy the code
(2) Select the seventh option, Advanced Options
(3) Select the first option
(4) Selection confirmation
(5) After confirming, close the interface and the system will automatically restart. After the restart, run the df command to check whether the extension is successful (I inserted a 64G SD card here).
