TM4C1231E6PZ: Missing arguments --board or --device error for newly created .syscfg file

Hi,

  You need to use Method 2 as Method 1 is missing configuration statements like GPIOPinConfigure(GPIO_PA2_SSI0CLK) which is used to configure GPIO PA2 as a SSI0CLK signal. 

manoj kumar said:

for method1 no .syscfg is required the GPIO PIn map can be done through the driverlib. in Method-2 .syscfg is required.

What do you mean that method 2 requires .syscfg? 

Can you just build the project with the below code? I don't have any problem building the project. What type of errors do you have if you don't have .syscfg. I mentioned several times to use an existing example as an existing example will have all the CCS project settings. For example, you can start off with a blinky project or a hello or project0 project. Try to build these simple examples. Later you can just replace the blinky.c with the below code for SSI. The TivaWare examples do not use .syscfg. This below example is from C:\ti\TivaWare_C_Series-2.2.0.295\examples\peripherals\ssi. This example configures the SSI as a master. Your above code seems to configure SSI as a slave module. But in either case, you need the GPIOPinConfigure() for proper operations so the SSI interface signals will come out on the PA5, PA4, PA3 and PA2.

//!
//! This example shows how to configure the SSI0 as SPI Master.  The code will
//! send three characters on the master Tx then polls the receive FIFO until
//! 3 characters are received on the master Rx.
//!
//! This example uses the following peripherals and I/O signals.  You must
//! review these and change as needed for your own board:
//! - SSI0 peripheral
//! - GPIO Port A peripheral (for SSI0 pins)
//! - SSI0Clk - PA2
//! - SSI0Fss - PA3
//! - SSI0Rx (TM4C123x) / SSI0XDAT0 (TM4C129x) - PA4
//! - SSI0Tx (TM4C123x) / SSI0XDAT1 (TM4C129x) - PA5
//!
//! The following UART signals are configured only for displaying console
//! messages for this example.  These are not required for operation of SSI0.
//! - UART0 peripheral
//! - GPIO Port A peripheral (for UART0 pins)
//! - UART0RX - PA0
//! - UART0TX - PA1
//!
//! This example uses the following interrupt handlers.  To use this example
//! in your own application you must add these interrupt handlers to your
//! vector table.
//! - None.
