Overview This application note describes how to load VTOS firmware images for the T2xxx processor family into DDR using U-Boot. Loading the firmware image over a serial connection Connect a serial cable between the UART1 interface of the T2xxx processor on your board and your host PC. Open a terminal emulator, such as TeraTerm, setting […]

1.0 License Server Overview All Kozio products require a license for full operation. These instructions cover the steps needed to work with floating licenses. A floating license is a license that can be used by any computer with network access to a license server. A floating license is tied to a single server, but can […]

Overview VTOS Developer includes a new feature to patch firmware files. The patching process enables a user to modify board specific data that is used by VTOS firmware. The user can modify items such as which UART to use for PC to Target communications and update Pin Mux Settings. The new feature was released in […]

Overview VTOS Tools includes the ability to bridge a USB device connection to an embedded UART on your board design.  This feature is part of the VTOS Scan USB Device task. Use the USB to UART bridging to verify communication to any embedded device that uses a serial/RS232 interface for communication.  Devices that provide a […]

DDR Initialization File Introduction This tutorial walks you through the process of creating a DDR Initialization file. There are a small number of Kozio Verification and Test OS (VTOS) firmware products that require DDR memory for execution. Using DDR memory is a requirement when there is not enough on-chip memory available for VTOS firmware. For […]

VTOS Firmware Images Overview VTOS Tools includes firmware images that run directly on the processor of your board design.  VTOS Tools provides separate firmware images for each product type (e.g. VTOS DDR, VTOS ScanCore, VTOS ScanEthernet, VTOS ProgramNOR).  This organization provides the best optimization of features and performance for each of the products in the […]

Overview The easiest deployment and use of VTOS DDR on the QorIQ P1xxx processor family utilizes a CodeWarrior TAP from NXP.   When using a CodeWarrior TAP, VTOS Developer automatically configures the P1xxx L2 cache memory, loads the correct firmware image, and performs all communication over the JTAG/COP connection to your board. VTOS DDR on the […]

USB Virtual COM Port Overview As a way of improving file transfer speeds from a Windows PC to a target processor running VTOS, Kozio provides a USB Virtual COM Port. This COM port is used by the VTOS Program NOR USB product to improve file transfer rates when programming a NOR flash device resident on […]

Overview This supplement describes Kozio’s Verification and Test OS (VTOS) features specific to the PowerQUICC II Pro MPC83xx processor family, manufactured by NXP. The MPC83xx series is based on the 32-bit Power Architecture® e300c1, e300c2, e300c3, and e300c4 (MPC603e) processor cores. Kozio provides a VTOS solution designed to run on most MPC83xx processors without porting or modification. Board […]
