LPMx.5 Debug Support Limitations

Description

The JTAG connection to the device might fail at device-dependent low or high supply voltage levels if the LPMx.5 debug support feature is enabled. To avoid a potentially unreliable debug session or general issues with JTAG device connectivity and the resulting bad customer experience Texas Instruments has chosen to remove the LPMx.5 debug support feature from common MSP430 IDEs including TIs Code Composer Studio 6.1.0 with msp430.emu updated to version 6.1.0.7 and IARs Embedded Workbench 6.30.2,  which are based on the MSP430 debug stack MSP430.DLL 3.5.0.1  http://www.ti.com/tool/MSPDS

TI plans to re-introduce this feature in limited capacity in a future release of the debug stack by providing an IDE override option for customers to selectively re-activate LPMx.5 debug support if needed. Note that the limitations and supply voltage dependencies outlined in this erratum will continue to apply.

For additional information on how the LPMx.5 debug support is handled within the MSP430 IDEs including possible workarounds on how to debug applications using LPMx.5 without toolchain support refer to Code Composer Studio User's Guide for MSP430 chapter F.4 and IAR Embedded Workbench User's Guide for MSP430 chapter 2.2.5.

Workaround

1.        If LPMx.5 debug support is deemed functional and required in a given scenario:

a)      Do not update the IDE to continue using a previous version of the debug stack such as MSP430.DLL v3.4.3.4.

OR

b)      Roll back the debug stack by either performing a clean re-installation of a previous version of the IDE or by manually replacing the debug stack with a prior version such as MSP430.DLL v3.4.3.4 that can be obtained from http://www.ti.com/tool/MSPDS.  

2.       In case JTAG connectivity fails during the LPMx.5 debug mode, the device supply voltage level needs to be raised or lowered until the connection is working.

Do not enable the LPMx.5 debug support feature during production programming.
