This document discusses how to use CodeWarrior for PA to debug Linux Kernel on QorIQ PowerPC platforms. It describes how to configure and build Linux Kernel to support CodeWarrior debugging, how to configure CodeWarrior IDE settings to prepare for Linux Kernel debugging, how to debug Linux Kernel in different booting up stages starting from attaching to the running u-boot.   1. Build Linux Kernel for Debugging   2. Create CodeWarrior Project and Set Attach Launch Configuration for debugging 2.1 Import Vmlinux to Create a CodeWarrior project 2.2 Configure the Attach Launch Configuration   3. Debugging Linux Kernel by Attaching to a Running U-Boot 3.1 Debugging Linux Kernel at the entry point 3.2 Debugging the Kernel before the MMU is Enabled 3.3 Debugging the Kernel after the MMU is Enabled

This document uses LS1043ARDB as an example to introduce how to use CodeWarrior for ARMv8 to connect to the bare board to do flash programming, how to use attaching method to debug u-boot and Linux Kernel on QorIQ LS ARM 64 bit target boards. In the document some new features of CodeWarrior for ARMv8 are used, so it is needed to download the latest CodeWarrior Networked Application Suite v2016.01 and install CodeWarrior for ARMv8.   1. CodeWarrior Connects to the Bare Board to do Flash Programing   2. Debug u-boot with CodeWarrior for ARMv8   3. Debug Linux Kernel by Attaching Running U-boot

Recently I have a chance to debug U-Boot on a LS1021ATWR board. Here is recording what I did, and also some notes and hints for other beginners.

1. You should have CodeWarrior TAP(CWH-CTP-BASE-HE)and Probe Tips for LS1024A(CWH-CTP-VSPA-YE)   2. Install CodeWarrior for QorIQ LS Series ARMv7 ISA Windows v10.0.4   3. Install CodeWarrior patch (LS1024A-2MA_Windows_SP.zip)forLS1024/MA 4. Connect this tool to LS1024A RDB board and run CodeWarrior environment.   5.Start the bootloader and stop it at Barebox command line   6. In CodeWarrior environment File->New->Codewarrior Bareboard project wizard to add a LS1024A project.     Run->Debug configuration->Debug   7. Window->Show View->Registers. Only ARM architecture registers you read here.   8. If you want to read peripheral device controller register, please use shell mode    Window->Show->Debugger Shell   CodeWarrior Debugger Shell v1.0 %> cmdwin::mem <device based address>+offset -s (use command “help cmdwin::mem” to get the detail )
