"SoC bringup" generally refers to the process of porting an operating system to a new embedded system that incorporates an SoC chip. This includes tasks such as:

- Assisting with the hardware debug by writing low-level test code to exercise memory and peripheral interfaces.
- Making sure that the bootloader can communicate with the specific boot device, and verifying that the entire boot process works correctly.
- Verifying that OS-level device drivers exist for the specific peripherals being used. This could include writing custom drivers for application-specific hardware.
- Making sure that the debugging mechanisms for application-level code are in place and working properly.

Together, these things are sometimes called a "board support package", or BSP.
