I can't use SPI on F28M36 concerto C2000

Hello all,

I am in trouble with the SPI of F28M36 in Simulink. I have a simple "code" :

When I deploy to hardware, nothing happen on the GPIO16 (SIMO) or even on the SPICLK.. I have a LSPCLK = SYSCLKOUT/4

Here is my SPI config :

With that configuration I have nothing on my board. I don't know what I can change to solve the problem on Simulink, so I began to check the generated code on CCS7 and I realize that the code is not compilable beacause there are some missing library. I have that error :

          C:\MATLAB\spi_ert_rtw>cd . 

      C:\MATLAB\spi_ert_rtw>if "all" == "" ("C:\PROGRA~1\MATLAB\R2017b\bin\win64\gmake"  -B -f spi.mk all )  else ("C:\PROGRA~1\MATLAB\R2017b\bin\win64\gmake"  -B -f spi.mk all )

The MW_SPI.h is missing and I can't find it on my computer.. I have already uninstall/install ControlSuite,Matlab SupportPackage

Can someone please help me ?

Hi,

The SPI SIMO and CLK pins should have values at the pins even though you are not reading the SOMI data using SPI Receive. Please check on following things

1) Ensure a known program is running on ARM core. You can create a simple model for ARM core and download before downloading the SPI model to c28x core.

2) Ensure the download goes through properly without any warnings or errors.

3) Are you using the ControlCard? Ensure the pins numbers you are checking are proper and corresponds to the GPIO number by checking the pinmap. For example, pins on the Docking station 67, 69, 71, 73 corresponds to GPIO16, 17, 18, 19.

4) If you want to debug in CCS. Use the project created after code generation to launch the CCS project directly and build in CCS (attached the image for reference). It will take care of all the dependencies required for the build including the shipped files like MW_SPI.h.

Let us know if further help is needed.

Thanks,

Aditya

Hi Loïc,

We have found the problem from our side for SPI block which caused problems for F28M36x processors. We will publish a fix in the next support package update. We are tracking the issue internally.

I have a workaround in the meantime: You can update MW_c28xGPIO.c with the attached corrected version for R2017b. MW_c28xGPIO.c is located in: (TIC2000_ROOT_DIR)\src

To find TIC2000_ROOT_DIR, you can run the following command: codertarget.tic2000.setup.internal.getSpPkgRootDir On most machines, the full path should look like C:\ProgramData\MATLAB\SupportPackages\R2017b\toolbox\target\supportpackages\tic2000\ Make sure to create a backup of the original file before proceeding.

I apologize for the trouble, we'll do the necessary to fix the problem as fast as possible.

Thanks,

Aditya

Hi Aditya,

Thanks for your answer ! I can't test your file right now but I'll tell you if it works.

Have a nice day !

[Loïc MICHEL]

It works with the new file !

Thank you !

Hi,

Could you please try to run the 'targetupdater' once and run through the complete setup process by pointing to CCSV, controlSuite path as required in the setup process. Please let us know if this helps.

Hi, Thanks for your answer. I have already done that. I have done it again and nothing change.. That's weird, beacause I've already made a program with UART and other things and it goes well. The CCS version could be a problem ? MW_SPI.h should be in the SupportPackage library folder ?

Thank you for your help,
