BOOSTXL-ADS7142-Q1 BoosterPack™ Plug-In Module

3.2

UNIFLASH Programmer for MSP-EXP432E401Y Software Programming

The MSP432E401Y LaunchPad™ ships with a default firmware program flashed on its memory. When a
LaunchPad™ is connected to the PC for the first time, its firmware needs to be updated for
communications with the BOOSTXL-ADS7142-Q1. The following steps describe the programming of this
firmware on the flash memory:

1. On MSP432E401Y LaunchPad™, remove the jumper JP6 from its default position and place it on the

JP1 jumper - 5V-OTG location as shown in

Figure 4

.

2. Connect the MSP432E401Y LaunchPad™ debug connector to an available USB port on the PC.

3. After the BOOSTXL-ADS7142-Q1 GUI is set up, select

Program Device

, as shown in

Figure 5

, from

the

File

menu option. This selection automatically recognizes the MSP432E401Y LaunchPad™ and

the FLASH program to communicate with the EVM.
