You can use the generic serial interfaces DCI-GSI1 and DCI-GSI2 for function bypassing, measurement, ECU calibration and flash programming. The broad range of available connector adapters lets you adapt the DCI-GSIs to individual electronic control units.
The current trend for modern automotive microcontrollers is towards higher levels of system integration, faster clock rates, increased on-chip RAM and flash memory, and more comprehensive I/O functionality. In this context, on-chip debug interfaces are becoming much more important for ECU software development.
Although both the DCI-GSI1 and the DCI-GSI2 are basically tailored for similar use cases, they differ in several details: For example, the DCI-GSI2 provides an open and standardized XCP on Ethernet interface for third-party tools to connect to. In addition, the DCI-GSI2 features bypassing without requiring any ECU source or HEX code changes, and enables very high measurement data throughputs and extremely fast measurement rasters via GBit Ethernet.

1) The DCI-GSI1 uses chip-internal overlay units of the MPC56x. There is an error in some versions of MPC56x chips with regard to using these overlay units; Freescale has confirmed this (published as CDR_AR_1073). Ensure that your application or chip version is not affected by this error. You can also contact dSPACE to exclude problems in connection with this error.
