MSP430FR6047: MSP430FR6047

Hello Janet,

Is this a new board? If so, when you power it on, do you see anything on the LCD? I have seen a recent issue where some boards are being shipped with the wrong firmware. If that is the case, you will need to load the board with the latest firmware. It can be found below in the "water demo application" below. You can also find the latest GUI in the "USSSWLib" download.

Hi Eddie,

the board ever worked, but recently the signal cannot be probed though all the lamps are on.

how could we debug whether this is hardware or firmware issue?

regards,

Janet

Janet,

What firmware version are you using?  Also, can you check the revision of the MSP430FR6047 IC?  This is marked on the topside of the IC.  Rev. A is not supported in the latest firmware(2.20.00.04).  If you have a rev. A device, I recommend upgrading the IC to the rev. B device, which can be sampled from the TI e-store. 

You can also find some good troubleshooting information in the FAQ below.  #4 and #6 could help with your setup.

Hi Eddie, yes. i have downloaded the updated version SW to my PC. is it true that the version of firmware is updated automatically while connected to the board? I have checked the version of MCU of our board is rev. B. We indeed refer to the FAQ.pdf for troubleshooting. To decouple the transducer issue, the probes of oscilloscope was directly contact the point of board and connect with USB /PC with updated USS. But the configurations parameter such as excitation frequency /pulse number cannot either be probed in the oscilloscope after tuning the setting of oscilloscope. we doubt our issue is hardware issue. Shipping back this board and exchange a new board before warranty (Mar. 14th) maybe an alternative for us to continue out project. seeking for your advice. Thank you.
