4.1.1 Connect Latte to Board

This step establishes a connection between the PC running Latte and the AFE79xxEVM.

  1. In the scripts window, select the AFE79xx drop-down, then the bringup drop-down. Select setup.py. On line 13, verify that the chip version is 0x13. Press F5 to run the program.
  2. Check the Log window to verify that there are no errors. Check that the following line is displayed twice: Kintex RegProgrammer - USB Instrument created.
  3. Missing or obsolete drivers for the FT4232H chip in the AFE79xxEVM is a common error source. In Latte, use the View tab then USB Handles to check USB handle connections to Latte. There are four connections for the TSW14J58 and four connections to the EVM. Alternatively, use the device manager to verify a connection between the PC and the EVM by checking the USB instantiations.
  4. Update your PC with the appropriate driver, if necessary.
