2. Introduction
This document is to introduce ROM-7421 evaluation boards and let the end users start module
evaluation easily and smoothly. It includes 2 parts of concepts: Start-up process and the detail
input/output connector and pin header specifications.
ROM-7421 evaluation boards are ROM-7421 RISC Qseven 2.0 module based on NXP i.MX6
Dual/Quad Plus 1GHz SoC and its corresponding carrier board ROM-DB7501 Advantech RISC
Qseven 2.0 Evaluation Carrier Board. It is highly recommended to completely read this document
before starting ROM-7421 board evaluation since it includes critical information as pin define,
handling process and connector information. In the meanwhile, you should also comply with all
warming notices and regulations you read in this document, it can prevent damaging ROM-7421
evaluation boards and spoiling those devices being connected.
Inappropriate installation may cause physical damage to ROM-7421 and its carrier board
ROM-DB7501, result in function loss or abnormal behaviors as kernel panic or unstable electric
currents in the evaluation kit. In this case, we would identify this inappropriate use of evaluation
kit as human negligence and it is excluded from our quality assurance policy.
