TI AM18x CPU Support

CPU Support Library for ScanExpress JET

Sitara™ ARM9™ AM18x microprocessors from Texas Instruments offer interfaces to a host of peripherals – peripherals that may be inaccessible to external probes, but are still at risk of faults and require thorough, at-speed testing. Corelis’ JTAG Embedded Test technology leverages the same microprocessor used to run the system to functionally test, verify, and program these peripherals – non-intrusively and at system speed.

Corelis ScanExpress JET™ makes full use of the ARM9™ core; by taking control of the system JTAG port, ScanExpress JET provides convenient development and execution of the complete Corelis functional test suite for supported system peripherals – right out of the box.

Standard and Custom Tests

TI AM18x CPU Support for ScanExpress JET includes automatic test generation for commonly used peripherals.

CPU Initialization – Test basic communication and functions of the CPU.
SDRAM – Execute a full suite of at-speed SDRAM tests to catch hard-to-find faults.
NAND, NOR, & SPI NOR Flash – Test and program Flash using maximum CPU clock speed.
I2C Discovery – Scan the I2C bus to identify and communicate with connected devices.
UART Loopback – Verify UART communication via a simple loopback cable.
Ethernet Loopback – Test Ethernet functions using a simple loopback cable.
Power Management IC (TPS65070) – Ensure that the power management system is fully functional.

Custom Tests

The ScanExpress JET development system includes a powerful scripting language and integrated script debugger; write your own tests or load compiled code right from the JET integrated development environment.
