CCS/TIDA-050011: TIDA-050011 Reference Design / TIDA050011FW problems

Tool/software: Code Composer Studio

Hi!

I'm trying to run the sample code (TIDA050011FW) for the "Various LED Ring Lighting Patterns Reference Design" but unfotunately no LEDs are blinking after flashing the FW.

First thing I tried was to measure the I2C clock on the launch pad because in  my opinion there should always a commuication with the LP5024 to see..... but I clouldn't measure any thing at the provided SCL Pin (P6_5).

What I'm using:

- MSP432P401R Launch Pad

- CCS

I'm able to build the Software with no errors....I have only two warnings which are below but I thing these warnings are not critical. 

1) Description Resource Path Location Type Product SimpleLink MSP432P4 SDK v1.60.0.12 is not currently installed. A compatible version 3.40.1.02 will be used. TIDA050011FW TIDA050011FW Problem

2) Description Resource Path Location Type This project was created using a version of compiler that is not currently installed - 16.9.4.LTS [MSP432]. Another version of the compiler will be used during build - 20.2.0.LTS. See 'Help > Install New Software' and select 'Code Generation Tools Updates' to check if this compiler is available through a CCS update. Visit <a href="liveaction:OpenAppCenter">CCS App Center</a> to get the latest compiler support. Or <a href="software-dl.ti.com/.../a> and install the compiler, then register it with CCS through 'Preferences > CCS > Build > Compilers'. TIDA050011FW properties Problem

To check if my system is generally working I flashed the "gpio_toggle_output_MSP_EXP432P401R_nortos_gcc" DriverLib example from the TI Resource Explorer. Flashing went well....LED on P1.0 was blinking and I could also adjust the frequency of the led.....so system is generally ok for me.

My question now to you:

Could you please check the software and let me know if everything is ok with it?

I will start to today to check if the mapping of the pin and other basic things are ok but it will take some time becaue it's the first time for me to work with TI's launch pad and its sw structure.

Thank's for your help in advance!

    Hey Thomas,

    Do you have pull-ups on the I2C line?  Were they just constantly high?   Did you run the code with the debugger to see if it's hanging anywhere?   

    I think your errors are probably okay but it's possible something with the I2C driver has changed since v1.6 of the MSP430P4 SDK.  Can you try one of the I2C master examples from TI Resource explorer just to see something working on your I2C lines?

    I have an MSP432P401R launchpad but I don't have access to an I2C board right not to really test with.  Maybe later today or tomorrow I can at least try building the code in my environment and flashing to the board.  

    Thanks,
