Hardware

After this interface enumerates, a host application is needed to interface with it and issue BSL commands

to access the MSP430's firmware. The MSP430 USB Developers Package includes a firmware updater

application that uses the USB BSL to download programs. For its input, it uses TI-TXT object-code files.

TI-TXT is a simple text-based object-code format that used with MSP430 MCUs to store and distribute

compiled code. These files can be generated by CCS or IAR. TI-TXT files for the software examples are

included in the zip file (\bin\simpleBackchannel.txt and \bin\emulStorageKeyboard.txt).

See the application report USB Field Firmware Updates on MSP430 MCUs (SLAA452) for information

about designing firmware update into your USB application. Additional information about the MSP430 BSL

can be found in the MSP430 Programming Via the Bootstrap Loader User's Guide (SLAU319).

2.7 BoosterPack Pinout

The F5529 LaunchPad adheres to the 40-pin LaunchPad pinout standard. A standard was created to aid

compatibility between LaunchPad and BoosterPack tools across the TI ecosystem.

The 40-pin standard is backward-compatible with the 20-pin one used by other LaunchPads like the MSP-

EXP430G2. This allows 20-pin BoosterPacks to be used with 40-pin LaunchPads.

This having been said, while most BoosterPacks are compliant with the standard, some are not. The

F5529 LaunchPad is compatible with all 20-pin (and 40-pin) BoosterPacks that are compliant with the

standard. If the reseller or owner of the BoosterPack does not explicitly indicate compatibility with the

F5529 LaunchPad, you might want to compare the schematic of the candidate BoosterPack with the

LaunchPad to ensure compatibility. Keep in mind that sometimes conflicts can be resolved by changing

the F5529 device pin function configuration in software. More information about compatibility might also be

found at http://www.ti.com/launchpad.

Figure 23 shows the 40-pin pinout of the F5529 LaunchPad.

Note that software's configuration of the pin functions plays a role in compatibility. The F5529 LaunchPad

side of the dashed line shows all of the functions for which the F5529 device's pins can be configured.

This can also be seen in the MSP430F5529 data sheet. The BoosterPack side of the dashed line shows

the standard. The F5529 function whose color matches the BoosterPack function shows the specific

software-configurable function by which the F5529 LaunchPad adheres to the standard.
