The Kozio CCS Tool is a command line utility used to optimize VTOS Tool connection settings when using a CodeWarrior TAP as a JTAG connection to the circuit board. This utility will attempt to discover an optimal JTAG TCK setting by cycling through multiple JTAG clock values and running a series of tests at each clock setting.
Kozio provides a line of tools under the label of VTOS Tools™.
VTOS DDR™ is used to calibrate and validate DDR memory settings on a custom circuit board design. This tool automates the process of finding optimal DDR configuration values along with running a comprehensive suite of memory tests. This tool is also used in manufacturing to quickly validate DDR memory on newly assembled circuit boards.
VTOS Program™ is used to transfer files and program Flash memory. This tool makes it possible to use a fast connection, such as Ethernet or USB, to transfer files to the target circuit board. The programming step takes advantage of the fastest processor speed and buffering in order to program the NOR, NAND, or MMC device as quickly as possible. This tool is used in manufacturing to automate and speed up the programming process.
VTOS Scan™ is used to test hardware busses and devices before the boot loader or operating system run. This fast pre-boot step is valuable in manufacturing to quickly validate the hardware before final assembly and running the final application. There are several VTOS Scan products for testing various hardware components. For example, VTOS Scan Plus™ validates GPIO, I2C, SPI, UART, Ethernet PHY, SD/MMC, and SDIO devices. VTOS Scan Ethernet™ provides internal, PHY, and external packet testing at selectable interface speeds. VTOS Scan PCI™ provides PCI Express discovery, memory mapping, and discovered part verification. VTOS Scan USB™ provides USB enumeration and part validation, at the fastest interface speeds. Additional VTOS Scan products are being released per customer demand.
Each VTOS Tool provides firmware that runs on the target circuit board without porting or configuration. When using a CodeWarrior TAP as your JTAG connection to your circuit board, each VTOS Tool will automatically load firmware and use the JTAG connection for communications - for running programming and test commands.
