TI Jacinto 7 Edge AI EVM setup

The EVM setup

This EVM page it's meant to show the user the Jacinto 7 EVM peripherals connections and boot modes necessary for the Edge AI, Linux, and RTOS SDKs.

For more details visit https://www.ti.com/tool/J721EXCPXEVM.

Requirements:

• TDA4VM/J7ES EVM
• 12 V power supply
• Ethernet cable
• UART cable
• Minimum 16GB high-performance SD card
• USB camera
• Full HD eDP display

The EVM connections

Boot mode switches

In order to allow the EVM to boot, please follow this switches configuration:

Configuration

The switches SW1, SW2 and SW3 are called configuration switches. Depending on how this switches are set, the system on module can fulfill different functions, check the next table:

Switch Name	Default Condition	Signal	Operation
SW1.1	ON	LPDDR4_IO_SEL	Selects the I/O voltage level for LPDDR4: ‘0’ (OFF) = Selects 0.6 V I/O for LPDDR4X,‘1’ (ON) = Selects 1.1 V I/O for LPDDR4
SW1.2	OFF	SEL_SOC_I2Cn	MUX to select I2C Interface for PMICs: ‘0’ (OFF) = PMIC I2C to SoC WKUP interface, ‘1’ (ON) = PMIC I2C to External Header (test mode only)
SW2.1	OFF	SEL_GPIO8_ALT	Selection for PMIC Watchdog Timer/GPIO8: ‘0’ (OFF) = PMIC watchdog timer control is set with SW2.2, ‘1’ (ON) = PMIC I/O used for GPIO8 (test point)
SW2.2	ON	LEOA_WDOG_DIS	Enable/Disable selection for PMIC Watchdog Timer: ‘0’ (OFF) = PMIC watchdog timer is enabled, ‘1’ (ON) = PMIC watchdog timer is disabled (requires SW2.1 to be set to OFF)
SW3.1	ON	SOC_SAFETY_ERRz	Option to combine SOC_SAFETY_ERRz with MCU_SAFETY_ERR and PMIC: ‘0’ (OFF) = SOC_SAFETY_ERRz (Main) is isolated from PMIC, ‘1’ (ON) = SOC_SAFETY_ERRz (Main) is connected to PMIC
SW3.2	OFF	SOC_PWR_EN	Manual method of enabling PMIC: ‘0’ (OFF) = PMIC enabled by EVM system, ‘1’ (ON) = PMIC enabled manually (test mode only)
