Corelis adds SPI and I2C Programming

Boundary Scan System Adds EEPROM Support

Corelis has announced the addition of direct I2C and SPI-based device programming capabilities for the ScanExpress Boundary-Scan system . The SPI and I2C interfaces are independent of the JTAG test interface; this means that the user can use the same JTAG controller to test the board and perform direct programming of serial EEPROM and flash memories without removing the JTAG connector or switching to a dedicated SPI and I2C programmer.

To simplify the application of direct programming, the user needs only to enable the direct programming option on the Test Programming file Generator (ScanExpressTPG), to create the SPI and I2C programming files. The programmer automatically detects the file type and programs the device using either the SPI protocol or the I2C.

Using the new direct programming port, serial FLASH/EEPROM devices can be programmed at speeds up to the device theoretical programming time. This is significantly faster than programming the devices indirectly using JTAG, typically 10 times faster and often surpassing this, depending on target configuration. Programming capability offered by the new port also allows versatile I2C and SPI device access, a useful benefit when JTAG access is not provided.
