The recently-introduced S32Z and S32E extend NXP’s S32 Automotive Platform and target up-to-date consolidated domain and zonal vehicle architectures. Designed to provide the real-time behavior of microcontrollers, but with a combination of gigahertz speed, safe multi-app integration and memory expansion capabilities, the devices target propulsion domain control, electrification and safety applications.

With its UDE debugger platform, PLS gives developers access to the S32Z2 and S32E2 devices. The eight main Cortex-R52 processor cores, the Cortex-M33 system management and communication cores as well as the Generic Timer IP Module (GTM) are all visible and can be controlled within one common debugger instance. There is no need to open separate debugger instances for the different core architectures. The UDE allows debugging of C/C++as well as assembly code for the Cortex-based cores including the Arm and Thumb-2 instruction set. Debugging of the Multi-Channel Sequencer (MCS) of the GTM can be conducted on assembler as well as C code level. In which UDE supports GTM-C compilers from various compiler vendors.

The MemTool add-on, which is an integral component of UDE, provides functions that enable simple and secure programming of the integrated flash memory as well as the external QuadSPI NOR, eMMC and SDHC NAND memories and offers also support for OCOTP (On Chip One-Time Programming). 

By using the multicore run-control management, UDE allows developers to control the cores of the S32Z2 and S32E2 processors using traditional run-mode debugging, i.e. with breakpoints or single-stepping, either all together, in groups, or individually. All cores in such a run-control group can be started and stopped almost synchronously. This helps to keep a consistent state of the respective application during debugging. Multicore breakpoints also simplify the debugging of complex applications, especially in shared code. A multicore breakpoint is effective, no matter which core is currently executing the specific code.

With UDE 2022, the debugging capabilities for MCS channel code of the GTM have been extended to include breakpoints and single stepping. These features relay on new hardware debug functions that are available with the GTM v4.1, which is integrated in the NXP S32Z and S32E real-time processors.

For non-invasive debugging and runtime analyses of multicore applications, UDE provides extensive functions based on recorded trace information from the device’s Arm CoreSight trace system. This allows both the program flow and data transfers to be recorded. UDE provides comprehensive configuration options for the ETMv4 of the Cortex-R52 cores as well as the ETM-M33 of the Cortex-M33 cores in order to filter for example the trace data to be recorded. In addition to the core trace, the transactions via the NoC can also be observed by the trace system and investigated with UDE. For this, too, the UDE offers wide-ranging configuration options for filtering the data. The trace support for the GTM, including program trace for the MCS channel programs as well trace of GTM signals, is in preparation.

For recording the trace data, either the UAD2next or the UAD3+ from the PLS’ Universal Access Device family can be used. To store trace data, the UAD2next features 512 MB of trace memory and the UAD3+ up to 8 GB. The fast download of the trace data from the chip towards the UDE is done via the High SpeedSerial Trace Port (HSSTP) of the S32Z2 and S32E2 processors.

“Thanks to the long-standing cooperation with NXP and as NXP Gold Partner, PLS can offer a high-quality debugging, system analysis and test tool in time for the launch of the NXP S32Z and S32E real-time processors. Thus, PLS continues offering developers comprehensive and reliable support for their application development,” says Jens Braunes, Product Marketing Manager at PLS.

The solution is demonstrated at embedded world 2022 in Hall 4, Booth 4 310.
