About OS awareness

DS-5™ provides support for a number of operating systems that can run on the target. This is called OS awareness and it provides a representation of the operating system threads and other relevant data structures.

The OS awareness support in DS-5 Debugger depends on the OS version and the processor architecture on the target.

DS-5 Debugger provides OS awareness for:

  • ThreadX 5.6: ARMv5, ARMv5T, ARMv5TE, ARMv5TEJ, ARMv6M, ARMv7M, ARMv7R, ARMv7A

  • μC/OS-II 2.92: ARMv6M, ARMv7M, ARMv7R, ARMv7A

  • μC/OS-III 3.04: ARMv6M, ARMv7M, ARMv7R, ARMv7A

  • embOS 3.88: ARMv5, ARMv5T, ARMv5TE, ARMv5TEJ, ARMv6M, ARMv7M, ARMv7R, ARMv7A

  • Keil CMSIS-RTOS RTX 4.7: Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4, and Cortex-A9 processors

  • FreeRTOS 8.0: ARMv6M, ARMv7M, ARMv7R, ARMv7A

  • Freescale MQX 4.0: Freescale-based Cortex-M4 and Cortex-A5 processors

  • Quadros RTXC 1.0.2: ARMv5, ARMv5T, ARMv5TE, ARMv5TEJ, ARMv7R, ARMv7A.

Note

  • By default, OS awareness is not present for an architecture or processor that is not listed above.

  • OS awareness support for newer versions of the OS depends on the scope of changes to their internal data structures.

  • OS awareness in DS-5 Debugger does not support the original non-CMSIS Keil RTX.

The Linux kernels that DS-5 Debugger provides OS awareness for are:

  • Linux 2.6.28, ARMv7A

  • Linux 2.6.38: ARMv7A

  • Linux 3.0: ARMv7A

  • Linux 3.11.0-rc6: ARMv7A

  • Linux 3.13.0-rc3: ARMv7A

  • Linux 3.6.0-rc6: ARMv7A

  • Linux 3.7.0: ARMv7A

  • Linux 3.9.0-rc3: ARMv7A

  • Linux 3.11.0-rc6: ARMv8A.

Note

Later versions of Linux are expected to work on ARMv7A and ARMv8A architectures.
