4.5 MSI Example

This test setup is intended for testing the PCIe MSI RC project pcie_msi_irq_rc_am243x-evm_r5fss0-0_nortos_ti-arm-clang in combination with the PCIe EP example project pcie_msi_irq_ep_am243x-evm_r5fss0-0_nortos_ti-arm-clang.

  1. Connect two TMDS243EVM or two TMDS64EVM through unmodified cable PCIE_FLEX_NOCLK.

  2. For first TMDS243EVM open CCS, import and build pcie_msi_irq_rc_am243x-evm_r5fss0-0_nortos_ti-arm-clang. Open designed for target configuration and connect with target. Perform system reset and load the example application.
  3. Connect to first TMDS243EVM through FTDI USB for UART port using serial terminal emulator program SER_TER.
  4. For second TMDS243EVM open second CCS application (this can require an additional workspace), import and build pcie_msi_irq_ep_am243x-evm_r5fss0-0_nortos_ti-arm-clang. Open designed for target configuration and connect with target. Perform system reset and load the example application.
  5. Connect to second TMDS243EVM through FTDI USB for UART port using serial terminal emulator program SER_TER.
