Run + Stop Mode Debugging for Linux
Today two different types of debuggers are used to develop Embedded Linux applications. To implement the destination hardware, a JTAG debugger is first used.
As soon as the main features of the Embedded Linux application are running on the destination hardware, GDB is often used in the first step of the debugging process. In Stop Mode Debugging using a JTAG debugger, both the processor and the entire system
stop at a breakpoint. Information about the processor and the destination hardware can then be displayed over the JTAG interface. Run Mode debugging using GDB, on the other hand, only halts the selected process while the main system continues running.
Both systems have their strengths and weaknesses. At Embedded World 2007, Lauterbach will present an integrated Linux debugger that combines both debugging concepts. In this way, programmers can use the strengths of the two approaches on a common user
interface, which will considerably shorten the development cycle of Embedded Linux applications.
This option is now available in the latest software release for all TRACE32 users with a debugging license for ARM. A version for PowerPC will be available shortly.
