Test and debug tools for Freescale’s latest Qorivva automotive SoCs

September 03, 2014 // By Graham Prophet
Offering third-party support to Freescale’s introduction of its latest Qorivva derivates, PLS Programmierbare Logik & Systeme has its Universal Debug Engine (UDE) for the MPC5746M, MPC5777M, MPC5748G, MPC5746C, MPC77xK and MPC574xP multicore Systems-on-Chip (SoCs).

Pre-configured setups of the UDE ensure an uncomplicated first connection as well as fast and reliable programming of the flash memory integrated in various sizes on the Qorivva devices. With help of the UDE's multicore/multiprogram loader, the relevant program codes and the corresponding debug information can be flexibly assigned to individual cores.

The heterogeneous structure of the SoCs is fully supported; besides the main cores, depending on the type, the devices can contain further programmable units such as a Generic Timer Module (GTM) or a Hardware Security Module (HSM). By core-specific grouping of debugger windows (optionally with automatic fade in and fade out depending on the active core, as well as different colouring) UDE-users are provided with an optimal overview of their complete multicore system in one single consistent user interface.

Control of the diverse cores by the debugger is carried out via the so-called multi-run control function, which enables an almost synchronous start and stop of the various cores by making use of debug logic integrated on the respective chip. In addition, debugging is simplified by the multicore breakpoints newly implemented in the UDE. Using that feature a simultaneously-acting breakpoint for all cores can be set in shared code. Data breakpoints allow the recognition of read and/or write accesses to a variable. A certain expected value can even be optionally taken into account.

In optimisation of the UDE, particular attention was also given to efficient support of all possible trace variants. While data transfer takes place via a conventional parallel port with the types MPC5746C, MPC5748G and MPC574xP, a serial high-speed interface that is based on the Aurora protocol is available for the MPC5746M, MPC577xK, MPC5777M and MPC574xP devices. This offers type-dependent four or two lanes each with 1.25 Gbps data transfer rate, which are processed without limitations by the Aurora trace pod of the Universal Access Device (UAD) 3+. For parallel trace, users can make use of a
