CCS/MSP430FR2433: Please review my schematic for Custom board of msp430fr2433

user6202586

Part Number: MSP430FR2433

Tool/software: Code Composer Studio

Hello

I wrote firmware for a certain project of mine using the Launchpad of msp430fr2433. Now I want to design a custom board that just has the micro and can be programmed using the launchpad.

I designed the board and made manual connections with the required pins and connected them to the J101 on the launchpad. I connected SDWTCK, SBWTDIO, P1.4, P1.5, 5V, and Gnd. I also pulled SBWTDIO high with a 47K resistor.

Could you please review my schematic and let me know if it's good? I want to double-check before I order this board.

Hi,

I found you don't add Cap in RST pin, we recommand add this cap(1nF),

Other Sch, I do not found any problem.

Thanks

Best Regards

Will do.

Thank you

Hello

So I made the PCB board for the schematic and I tried it out for the first time today. I connect 3.3V, Gnd, SBWTDIO, and SBCLK pins directly to the microcontroller. It still didn't work.

I tried to put the firmware on the micro via CCS bt when I run it, It say's "MSP430: Error connecting to the target: Unknown device". I have attached a picture of the setup.

The micro is powered directly from the launch pad(3.3V). I measured it as well. What did I miss?

Hi,

You can check your soldering is well or not, and the capacitance on the RST pin is 1nf?

Thanks!

Hello

The capacitance on the Rst pin is 50nF. Would this be a problem?

I'm working on the solder.

Hi Varun,

You need to change this cap to 1nf, this value of cap have to less than 2.7nf if you use SBW.

Because the RST pin will use to transmit data in SBW connect.

Thanks!

Johnson
