MSP430G2553: flash program using UART communication on MSP430G2553

mahdhu kommu1

Part Number: MSP430G2553

Hi All,

is it possible to flash program in to MSP430G2553 using UART communication? means don't want to use any JTAG(MSPFET), simple want to use USB to UART cable from PC, that UART pins connect to MSP430 and flash. my file size(.out file) is 356Kb. kindly help me.

Hi Madhu,

The MSP430G2553 has a UART BSL interface that can be used to program the part. However, it's more complex than simply connecting a USB to UART cable to the MSP430. You need to ensure the voltage level is correct for the MSP430 as the PC is most likley running at a higher voltage. I recommend reading through the MSP430™ Flash Device Bootloader (BSL) User's Guide and the following E2E posts that have tried something similar:

e2e.ti.com/.../301019
e2e.ti.com/.../1709194
e2e.ti.com/.../311015

I also suggest doing a quick google search on programming the G2553 using the BSL and you can find many more resources of others doing the same thing.

Best regards,
Caleb Overbay
