UC-7110 Software Architecture

The pre-installed µClinux Operating System used by UC-7110 follows the standard µClinux architecture, making programs that follow the POSIX standard easily ported to UC-7110 by using the GNU Tool Chain provided by www.uClinux.org. In addition to the Standard POSIX API, device drivers for the buzzer, and UART for the serial ports are also included.

UC-7110’s Flash ROM has more than one smaller partition, which contain the Boot Loader, Linux Kernel & Root (/) File System Image, and User Directory partitions.

For most applications, users often spend a lot

 

 

time maintaining the operating system and

modifying the system configuration. In order to

partition a “User Directory” for storing the user’s

 

 

system configuration parameters.

 

 

UC-7110 has a built-in mechanism that prevents

system crashes, helping preserve system

reliability. The procedure is described below.

Boot Loader

When the Linux kernel boots up, the kernel

mounts the root file system and then enables

 

 

services and daemons. The kernel also looks for

 

 

the system configuration parameters via rc or inittab.

 

 

Normally, the kernel uses the User Directory to boot up the system. The kernel will only use the default configuration _etc & _home when the User Directory crashes.

UC-7110 uses ROMFS for the Linux kernel image, Root File System, and Protected configuration,
