3.4.7 UART Interface
Four UART ports of the SoC are interfaced with FT4232H for UART-to-USB functionality and terminated on a
micro B connector (J26). When the AM64x EVM is connected to a Host using the provided USB cable, the
host can establish a Virtual Com Port which can be used with any terminal emulation application. The FT4232H
is bus powered. Virtual Com Port drivers for the FT4232H can be obtained from
The FT_Prog has three modes of operation: Idle Mode, Program Mode and Edit Mode. FT_Prog programming
parameters can be saved in files referred as EEPROM templates. Once defined, these EEPROM templates can
be loaded by FT_Prog and used to program EEPROMs.
• Idle Mode is the initial mode of operation when the program is launched.
• Edit Mode is used to edit the settings of an EEPROM template
• Program Mode is used to Program and Erase the device EEPROM(s).
