6.4 BSL7

BSL Module

Category

Software in ROM

Function

BSL does not start after waking up from LPMx.5

Description

When waking up from LPMx.5 mode, the BSL does not start as it does not clear the Lock I/O bit (LOCKLPM5 bit in PM5CTL0 register) on start-up.

Workaround

1. Upgrade the device BSL to the latest version (see Creating a Custom Flash-Based Bootstrap Loader (BSL) Application Note - SLAA450 for more details)
OR
2. Do not use LOCKLPM5 bit (LPMx.5) if the BSL is used but cannot be upgraded.
