When writing drivers, it is generally necessary to add node information to the device tree, which provides a way to add device information directly to the drive.The drive template for I²c is as follows#include The SPI driver template is as follows#include The SPI and IIC drivers under Linux are not programmed to

, how to know the size of a bare deviceThe more stupid way is to find out that the bare device corresponds to the actual block device, and then use Fdisk-l/dev/[h,s]dxn look at the size of the piece of equipment is good.The simpler approach is to use the Blockdev command to calculate, such as:#blockdev--GETSIZE/DEV/RAW/RAW11171875011718750 indicates how many OS Bliock are there.Typically an OS block size is

The driver can be compiled in two ways. One is to statically compile the program into the kernel, and the other is to compile the program into a module for dynamic loading. Because uClinux does not support dynamic module loading, and embedded Linux cannot use insmod/rmmod as flexibly as Desktop Linux does, so here we will only introduce how to statically compile the device driver into the uClinux kernel.The following uses uClinux as an example to desc
