Tool/software: Code Composer Studio

Hi,

i am trying to configure the spi1 as master and the spi2 as slave as per the given examples provided by halcogen for the other controllers.

But for TMS570LC4357, i am unable to receive the data for the slave.

I have also tried with the spi1-spi3 communication as provided here:

    Hello,

    If you are trying the code from the link above, please check your wiring. The code from link above is working at my place.

    Are you using LaunchPad or HDK?

    At LaunchPad connections have to be:
    MIBSPI1CLK @ J5.7       --->  MIBSPI3CLK @ J1.7
    MIBSPI1SIMO[0] @ J6.6 ---> MIBSPI3SIMO @ J2.6
    MIBSPI1SOMI[0] @ J6.7 <--- MIBSPI3SOMI @ J2.7
    MIBSPI1CS[0] @ J6.3    ---> MIBSPI3CS[0] @ J5.5

    HI,

    I still cannot able to provide the communication between either spi1-spi2 communication or spi1-sp3. can you please provide the settings for the halcogen that we need to incorporate to exist the communication between it.

    i followed the following steps for the halcogen.

    1) Driver TAB
     - Select SPI2
     - Select SPI1
     2) VIm Channel 0-31
     - Enable SPI2 Level 0 and Level 1 channels.
     3) SPI2 TAB
     - SPI2 Global SubTAB
     - Uncheck Master Mode
     - Uncheck Internal Clock
     - SPI2 Port SubTAB
     - Uncheck DIR for CS 0
     3) SPI1 TAB
     - Have it default
     4) Generate Code.

    Hello,

    Did you succeed with SPI1-SPI3 communication using the attached project from the link above? If this project is not working for you may be you have connection problem. Did you observe whether data is transmitted from SPI1 (using oscilloscope, for example )?

    Best regards,
