ScanExpress JET – Freescale i.MX6 CPU Support

Freescale i.MX6 CPU Support

CPU Support Library for ScanExpress JET

The powerful and versatile NXP i.MX6 family of applications pro cessors are the central core of a broad range of embedded systems; a core that can be leveraged to test embedded system functionality across the product life-cycle.

ScanExpress JET™ takes control of the ARM® Cortex®-A9-based i.MX6 series of processors to functionally test, verify, and program SDRAM, NOR Flash, and additional peripherals to ensure interface integrity and peripheral functionality. JET technology provides convenient system hardware verification throughout the entire product life-cycle, even before boot and application code are available.

Standard and Custom Tests

ScanExpress JET can be used to generate a standard set of tests or to create custom test scripts for peripherals connected to the microprocessor.

  • CPU Initialization -Test basic communication and functions of the CPU.
  • SDRAM Test – Execute a complete suite of SDRAM tests to identify functional faults at full CPU speed.
  • NOR Flash – Test, program, and verify NOR Flash at high speeds using a simple JTAG interface.
  • Custom Tests – The ScanExpress JET development system incudes a powerful scripting language and integrated script debugger; write your own test scripts or load compiled code right from the JET integrated development environment.

Supported Processors

Supported NXP i.MX6 parts include all solo, dual, and quad-core CPUs with Cortex-A9 cores.

Applications

Test Engineers

JET is able to increase board test coverage by quickly combining boundary-scan testing with at-speed functional testing.

Design Engineers

JET assists in prototype debug before test firmware or test fixtures are available

Firmware/Software Engineers

JET is able to save coding time through automatic test and diagnostic generation.

Field Application Engineers

JET can be used to field validate a customer board or upgrade firmware on-site.

Repair Engineers

JET can identify board failures quickly reducing the repair cost per unit.

ScanExpress JET 13 Point Benefit

The JTAG Embedded Test (JET) method extends coverage beyond popular boundary-scan techniques to virtually every signal of the UUT that is accessible by on-board CPU(s). This includes most of the remaining non-scannable, analog and I/O port resources.
