 # Debugging with QEMU
 
-> This page is work in progress
-
-This toolchain provides `qemu-system-tricore` and `tricore-elf-gdb` executable
-that can be used to run and debug your code in a simulated environment.
+This toolchain provides `qemu-system-tricore` and `tricore-elf-gdb` for running
+and debugging your code in a simulated environment.
 
 > QEMU support for Tricore architecture is incomplete. It provides only basic
 > CPU instruction decode (no interrupts or multi-core) and no peripheral is
 > available. Only core architecture from tc1.3 up to tc1.6.2 is supported

+The code below uses ELF executable built from
+[aurix-cmake-code-sample](https://github.com/NoMore201/aurix-cmake-code-sample)
+in debug mode (no optimizations and debug symbols enabled). It should work with
+any Tricore ELF file built with DWARF v3 debug symbols.
+
+First step is to run QEMU providing the ELF executable, enabling gdb stub for
+remote debugging and enable startup freeze option to be able to connect before
+running the emulation.
+
+```
+$ qemu-system-tricore -machine KIT_AURIX_TC277_TRB -kernel ./out/debug/src/aurix_sample_tc33x.elf -s -S
+```
+
+Next we run tricore-elf-gdb, set the architecture version to 1.6.2 and connect
+to QEMU gdb stub:
+
+```
+$ tricore-elf-gdb ./out/debug/src/aurix_sample_tc33x.elf
