<p><b>Neue Seite</b></p><div>The Lauterbach In-Circuit-Debugger supports Bluetechnix i.MX53 modules and boards.<br />
<br />
Web site: https://www.lauterbach.com<br />
<br />
== Demonstration files ==<br />
<br />
can be downloaded from our FTP server: [https://support.becom-group.com/releases/imx/mx53/config/lauterbach-cmimx53-demofiles.zip Link]<br />
<br />
<br />
This contains several Trace32 batch files (*.cmm):<br />
* ''demo.cmm:'' Based on Freescale Quick Start Board example<br />
* ''ddrstresstest.cmm:'' DDR Stress test, including DDR2 configuration sequence<br />
* ''u-boot.cmm:'' Load/attach to U-Boot and debug it<br />
* ''linux.cmm:'' Load U-Boot, Linux kernel, with Lauterbach Linux Awareness<br />
* ''linux-app-debug.cmm:'' Load U-Boot, Linux kernel, debug an application<br />
<br />
== Impressions ==<br />
<br />
The Lauterbach ICD and the TRACE32 software supports Linux kernel awareness, and hence lets you debug<br />
*Linux kernel<br />
*Linux kernel modules<br />
*Linux user space applications<br />
<br />
<br />
Here are some debugging impressions with Lauterbach JTAG Debugger and CM-i.MX53, debugging Linux:<br />
<br />
=== Linux kernel debugging ===<br />
<br />
[[Image:1-kernel started and halted.png|left|500px|Kernel started and halted]]<br />
<br />
Using linux.cmm batch file<br />
<br />
<br />
The Linux kernel boots to the login prompt, then the debugger halts it.<br />
<br />
<br />
B::Data.List is the code window, showing mixed C and assembly code from Linux's process.c file.<br />
<br />
B::TASK.DTask shows a list of all Linux tasks.<br />
<br />
B::var.frame shows stack frames.<br />
<br />
B::TASK.Process shows Linux userspace processes.<br />
<br />
<br style="clear: both" /><br />
=== Linux kernel module debugging ===<br />
[[Image:2-module loaded.png|500px|left|Kernel module loaded]]<br />
<br />
A kernel module (ism_mt9m025_camera) was loaded with the Linux Shell.<br />
<br />
<br />
B::TASK.MODule shows a list of loaded kernel modules.<br />
<br />
B::List shows the code of the module as it is loaded into RAM.<br />
<br style="clear: both" /><br />
[[Image:3-breakpoint-in-module.png|500px|left|Breakpoint in kernel module]]<br />
<br />
A breakpoint in the kernel module is set and hit.<br />
<br />
<br />
B::sYmbol.Browse is the symbol browser and lets you find the function mt9m024_init_mode().<br />
<br />
B::Break.List shows the breakpoints list.<br />
<br />
B::Var.REF shows current variables in this function after hitting the breakpoint.<br />
<br />
<br style="clear: both" /><br />
=== Linux application debugging ===<br />
[[Image:4-linuxapp-debugging.png|500px|left|Linux application debugging]]<br />
<br />
<br />
Using linux-app-debug.cmm batch file (and app_debug.cmm script)<br />
<br />
<br />
Debugger is prepared for process start; process is started in terminal. Debugger detects process start and automatically halts in main().<br />
<br />
<br />
B::Data.List shows application's code.<br />
<br />
B::TASK.Process shows processes - ''hello'' is current.<br />
<br />
