2.15 TIVA and Test Automation Header

The board supports two test automation features:

  • A USB-based virtual COM port, using the TIVA Test Automation Header.
    • The header allows an external controller to manipulate basic operations such as power down, PORz, warm reset, and boot mode control.
    • The AM263Px SOC I2C instance is connected to the TIVA Test Automation Header - FH12A-402-0.55H.
  • A 40 pin test automation header that allows an external controller to manipulate basic operations such as power down, PORz, warm reset, and boot mode control.

    • The Test Automation Circuit is powered by a dedicated 3.3V power supply (VSYS_TA_3V3) which is generated by a 5V to 3.3V buck regulator (TPS62177DQCR).

    • The AM263Px SoC I2C3 instance is connected to both the Test Automation Header and the boot mode IO expander (TCA6408ARGTR).

The following table details the Test Automation mapping.

Table 2-18 Test Automation GPIO and I2C Mapping
Signal NameDescriptionDirection
TA_POWERDOWNZWhen logic low, disables the 3.3V buck regulator that is used in the first stage of DC/DC conversionOutput
TA_PORZWhen logic low, connects the PORz signal to ground due to PMOS VGS being less than zero creating a power on reset to the MAIN domainOutput
TA_RESETZWhen logic low, connects the WARM RESETn signal to ground due to PMOS VGS being less than zero creating a warm reset to the MAIN domainOutput
TA_GPIO1When logic low, connects the INTn signal to ground due to PMOS VGS being less than zero creating an interrupt to SoCOutput
TA_GPIO3When logic low, disables the boot mode buffer output enableOutput
TA_GPIO4Reset signal for boot mode IO ExpanderOutput
TA_I2C_SCLI2C Clock signal used to communicate with bootmode IO expander to change the boot modes. Output
TA_I2C_SDA I2C Data signal used to communicate with bootmode IO expander to change the boot modes. Output
