Guide to Set Up Debugging Environment for Total Compute Software Stack

Arm Total Compute Solutions (TCS) is the platform for mobile computing, with double double-digit gains in CPU performance and efficiency to power the next generation of AI and immersive mobile gaming experiences.

Total Compute (TC) software stack is a reference software stack for the Arm Total Compute Fixed Virtual Platform (FVP). The TC software consists of firmware, kernel and file system components that can run on the associated FVP.

Some of its main components are as follows:

RSS firmware, which provides Hardware Root of Trust
SCP firmware, which is responsible for system initialization, clock and power control;
AP firmware, which is Trusted Firmware-A (TF-A)
Secure Partition Manager - Hafnium
Secure Partitions:
- OP-TEE Trusted OS in Buildroot
- Trusted Services in Buildroot
- Trusty Trusted OS in Android
U-Boot, which loads and verifies kernel and rootfs
Linux Kernel

This blog shows you how to set up the debugging environment step by step, including how to configure the debug environments for RSS, SCP, and AP.
