A debug probe () for controlling debugging of a target system () is described, the debug probe comprising an interface () comprising a plurality of pins (), debug control circuitry () to control debugging of the target system based on a digitally sampled level of at least one signal communicated through at least one of the plurality of pins, and measurement circuitry () to make a measurement of a property of the target system based on an analogue level of a signal received through said at least one of the plurality of pins.

Debug probe for measuring at least one property of a target system

A non-volatile mass storage device is provided comprising memory circuitry accessible to a host data processing device via a communication link. The non-volatile mass storage device comprises processing circuitry for locally accessing the memory circuitry of the file system and is capable of triggering generation of a file for storage on the memory circuitry by connection of the non-volatile mass storage device to the host data processing device. The generated file comprises information dependent upon a state of the non-volatile mass storage device. A corresponding method of operating a non-volatile mass storage device is provided and a computer program is provided for obtaining the information dependent upon the state of the non-volatile mass storage device, for locally accessing the memory circuitry and for generating the file for storage on the memory circuitry.

Data processing on a non-volatile mass storage device

A programmerfor a target deviceis provided with a mass storage interfacefor connecting to a hostso as to appear as a mass storage device to the host. A target programmeris responsive to an image transferred from the hostto the programmerto apply that image to the target device
