JTAG Module
Category
Software in ROM
Function
BSL does not exit to application code
Description
The methods used to exit the BSL per MSP430 Programming Via the Bootstrap Loader (SLAU319) are invalid.
Workaround
To exit the BSL one of the following methods must be used.
- A Power cycle
or
- Toggle the TEST pin twice when nRST is high and after 50us pull nRST low.
Note: This toggling of TEST pins is not subject to timing constraints. The appropriate level transitions on TEST pin, followed by a RST pulse after 50us, are sufficient to trigger an exit from BSL mode.
