6.30 JTAG27

JTAG Module

Category

Debug

Function

Unintentional code execution after programming via JTAG/SBW

Description

The device can unintentionally start executing code from uninitialized RAM addresses 0x0006 or 0x0008 after being programming via the JTAG or SBW interface. This can result in unpredictable behavior depending on the contents of the address location.

Workaround

1. If using programming tools purchased from TI (MSP-FET, LaunchPad), update to CCS version 6.1.3 later or IAR version 6.30 or later to resolve the issue.

2. If using the MSP-GANG Production Programmer, use v1.2.3.0 or later.

3. For custom programming solutions refer to the specification on MSP430 Programming Via the JTAG Interface User's Guide (SLAU320) revision V or newer and use MSPDebugStack v3.7.0.12 or later.

For MSPDebugStack (MSP430.DLL) in CCS or IAR, download the latest version of the development environment or the latest version of the MSPDebugStack

NOTE: This only affects debug mode.'
