F28M36 SD Card Example

Other Parts Discussed in Thread: CONTROLSUITE

Trying to get the SD Card example working on the F28M36 (Control Suite) and I am unsuccessful.  I have used 2GB/4GB/8GB/16GB cards and get FR_NOT_READY results on each.  I am using the Control Card.  Things I have tried:

1) Changing CRC code in send_cmd function, IE n=0 to n=0xFF as suggested in the forum.

2) Changed the pin mapping in mmc-concerto.c via:

SDC_GPIO_PORT_BASE, From GPIO_PORTD_BASE to GPIO_PORTR_BASE

SDC_GPIO_SYSCTL_PERIPH From SYSCTL_PERIPH_GPIOD to SYSCTL_PERIPH_GPIOR

This results in an FaultISR

At wits end here.  Why doesn't this work out of the box?  And why is there no documentation in the TRM on PORTR?

    Mark,

    I'm looking in to your issue. Which version folder are you getting the example from in controlSuite? Is there a file called set_pinout_f28m36x.c linked to your project? If not, try using the example from v202 folder. You may have to update controlSuite if you do not have this folder.

    Regards,

    I am using the example that is provided using the "Resource Explorer" SD Card Read M3.  Which automatically pulls in the project sd_card_m3 <V110>.  Thinking this was a problem, I tried to import the project in V202 but received this error:

    See details below.
      Warning: Project 'driverlib', referenced from 'sd_card_m3', could not be found. Please import this project manually.

    Which I attempted compile but once I got the configuration correct to build, I get a error in the linking

    Does the project have uartstdio.c linked to it? That should have the definitions for UARTFlushTx() and UARTStdioIntHandler(). 

    You should be able to find it in device_support\f28m36x\v202\MWare\utils\uartstdio.c if it does not. 

    Also, when you add files to your project, its best if you link to the file rather than copy it directly into the project.

    Benjamin,

    I was able to successfully compile and read the SD Card.  The solution was to:

    Delete sd_card_m3 project

    Import Existing CCS Project, [C:\ti\controlSUITE\device_support\f28m36x\v202\MWare\driverlib] w/ Linking

    Import Existing CCS Project, [C:\ti\controlSUITE\device_support\f28m36x\v202\F28M36x_examples_Master\sd_card] w/ Linking

    Change to Correct Device in project configuration

    Compile

    Now I can read the SD Card.

    Also it appears that the RAM configuration was my original problem.  It will not load with the RAM cmd file.
