In-System programming of Flash and CPLD
devices
Corelis ScanPlus tools allow users to program or reprogram Flash memory
devices or Complex Programmable Logic Devices (CPLDs) after the devices
have been soldered onto the printed circuit board.
As densities of CPLDs and flash memories increase and package sizes
decrease, it becomes difficult to program these devices with an off-line
CPLD or flash programmer. For designs that include a JTAG IEEE Std 1149.1
interface, it is possible to program these devices in-circuit, while soldered
in place.
Programming in-circuit is desirable in both development and production
environments. For development, engineers can reconfigure CPLDs, or change
code stored in flash memory devices during the development process. For
production, in-circuit programming allows devices to remain on the shelf
in an unprogrammed or blank state. These blank devices can then be installed
at assembly and programmed in-circuit, thus reducing programming and tracking
costs.
The in-circuit programming of CPLDs and flash devices is achieved in
different ways. For CPLDs, the device's own boundary-scan programming
capability is directly accessed by the ScanPlus programmer software. For
flash memories, which do not have their own boundary-scan capability,
the ScanPlus software uses the boundary-scan capability of the system
processor to take control of the address, data and control busses in order
to achieve programming.
