LAUNCHXL-F28379D: Boot mode configuration for SPI

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: C2000WARE

Hello,

I was trying to run the SPI codes given in C2000ware. I all the codes the below lines are mentioned :

"Other then boot mode pin configuration, no other hardware configuration is required "

so I wanted to ask that what is the boot mode pin configuration settings for SPI module on hardware.

There are 3 boot mode switches on the launchpad, how to set them for external mode instead of loopback.

    Hi Nisha,

    I'm not exactly sure what that note means, but I will follow up. Just to be clear, you want to take a SPI example from C2000ware and configure it to use external loopback rather internal loopback, correct? For that there is already an example using driverlib. Please see the example <spi_ex3_external_loopback_fifo_interrupts> in the path below.

    C:\ti\c2000\C2000Ware_3_03_00_00\driverlib\f2837xd\examples\cpu1\spi

    Note the external connections required by the code to run successfully. These are given in the source file.

    //! \b External \b Connections \n
//!  -GPIO25 and GPIO17 - SPISOMI
//!  -GPIO24 and GPIO16 - SPISIMO
//!  -GPIO27 and GPIO19 - SPISTE
//!  -GPIO26 and GPIO18 - SPICLK

    hello Gus,

    do we need to change the configuration of three boot mode switches present on the launchpad (which are set high high high by default.)

    Nisha,

    For debugging code with CCS, you can set the boot pins to the "wait boot mode" (refer to the F2837xD datasheet). This will have the CPU in a wait mode until CCS connects to the device.
