VTOS Scan™ Plus for SD/MMC and Ethernet PHY Testing
Fast Circuit Board Test
VTOS Scan is an embedded software tool provided by Kozio for testing various hardware bus interfaces and devices. VTOS San provides a fast and effective way to test your embedded device hardware before the boot loader and operating are loaded and running. VTOS Scan validates bare boards in seconds and provides excellent details for troubleshooting failing boards.
Early this year Kozio introduced VTOS Scan Base. This tool is focused on testing GPIO, I2C, SPI, and UART interfaces and devices. The tool provides both tests and low-level commands for hardware validation and troubleshooting. VTOS Scan Plus provides all the features of the Base product and adds in testing and low-level commands for SD, MMC, and Ethernet PHYs. VTOS Scan Plus takes hardware test coverage one step further by validating many common boot devices such as eMMC devices, and validating other communication channels such as wireless and Ethernet.
VTOS Scan Plus provides the following additional test coverage:
- SD Card: Perform a Device Exists test; perform a Verify test to verify the device’s manufacturer id, OEM id, and capacity; or perform an MD5 checksum on the data to verify the programming step.
- MMC: Perform a Device Exists test; perform a Verify test to verify the device’s manufacturer id, OEM id, and capacity; or perform an MD5 checksum on the data to verify the programming step.
- Ethernet PHY: Perform a Device Exists test; and perform a Verify test to verify device information.
With VTOS Scan Plus it is easy to set up a test configuration that quickly validates your hardware and then export the test script to be used with your test executive. Kozio provides vAccessTest which is a simple test executive and provides source code for understanding how to make vAccess calls for test automation.
