    Hi,

    the COM PORT mode of BSL_Scripter is used for UART based BSL, while the USB mode is for USB based BSL (found per default in MSP430 devices which has USB peripheral such as MSP430F55xx, MSP430F66xx, etc.).

    More information detailed information about MSP430 BSL can be found here:

    Hello,

    Can I program the flash memory directly on msp430f5529 by using USB based BSL. That means I connect USB module of msp430f5529 to computer's USB port. and then using bslscripter.exe or MSP430 USB Developers Package to program the code into the flash memory of msp430f5529.

    Thanks

    Yes,

    exactly, you got it right. You can either use the BSL_Scripter or MSP430 USB Firmware Updater to flash the main memory of the MSP430F5529.

    However please notice that you need to invoke the BSL to do that. For USB BSL there are two conditions which can invoke BSL when the device is powered by VBUS:

    • The device is powered up by USB and the reset vector is blank.
    • The device powers up with the PUR pin tied to VUSB

    This can be done for example by pressing down the BSL invoke button S3 on MSP-TS430PZ80USB while powering up the device by connecting the USB cable.
