Phytec i.MX7 PEB-D-RPI Manual

i.MX7: Evaluating the PEB-D-RPI Expansion Board
The phyBOARD-Zeta kit includes an expansion board (PEB-D-RPI) designed to facilitate the easy evaluation of certain interfaces available on PHYTEC i.
MX7 platforms. The following sections will detail how to use these features in the environments in which they are supported. These instructions assume
that you have properly connected the expansion board to the carrier board and have booted into a supported environment (U-Boot and/or Linux) using
BSP version PD18.2.0 or newer. If you are looking for information regarding Raspberry Pi HAT support, please see
PEB-D-RPI Expansion Board. The expansion board has the following features:

Use the following as a reference for the connector interfaces on the PEB-D-RPI expansion board that will be used in this document.
USB to Serial UART Interface
The i.MX7 is configured by default to use UART5 for console input and output over the carrier board X2 connector shown in the
section of the i.MX7 Quickstart . The USB to Serial UART interface on the PEB-D-RPI expansion board allows the use of UART1 and UART2 for serial data
over connector X6 shown in the above
UART2 is used by the M4 core in PHYTEC's FreeRTOS software.
