TMS570LS0432: Master-Slave SPI communication

Hello,

I am Using two TMS570LS0432 boards for Master-Slave SPI communication.

I configured both the boards in Halcogen as instructed https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/731608?tisearch=e2e-sitesearch&keymatch=tms570%20spi

In Halcogen(Version: 40.06.00) new project window I have selected family: TMS57LS04x and Device: TMS57LS0432PZ

Master

• Driver Enable: Select SPI1 Driver only*

• SPI1 Global TAB: Enable RxINT

• SPI1 Port TAB:

• Uncheck SOMI Direction

• Select SPI1 ENA GIO

• Select SPI1 SCS[3] GIO

• Select SPI1 SCS[2] GIO

• Select SPI1 SCS[1] GIO

• VIM Channel 0-31 TAB: Enable MIBSPI Level 0 & Level 1 Interrupts

Slave

• Driver Enable: Select SPI2 Driver only*

• SPI1 Global TAB:

• Unchecked Master Mode and Internal Clock.

• Uncheck SPI2 SOMI Direction

• Uncheck SPI2 CLK Direction

• Uncheck SPI2 SCS[0] Direction

• Make SPI2 SCS[3] GIO

• Make SPI2 SCS[2] GIO

• Make SPI2 SCS[1] GIO

• VIM Channel 0-31 TAB: Enabled SPI2 Level 0 and Level 1.

Pin Connections

Mater(SPI1)                              Slave(SPI2)

J1.7 --> MIBSPI1CLK               J10.24 --> SPI2CLK
J10.16 --> MIBSPI1nCS[0]       J10.21 --> SPI2CS
J2.6 --> MIBSPI1SIMO             J10.23 --> SPI2SIMO
J2.7 --> MIBSPI1SOMI             J10.22 --> SPI2SOMI

J10.4 --> GND                          J10.4 --> GND

I'm ensuring slave is ready before master sends data.

I am attaching CCS Project with .dil and .hcg files
