VxWorks MB Support Package for PCI Device Management and Debugging

The STT MB Support Package for VxWorks offers comprehensive tools for detecting and initializing Universe II chips and managing PCI devices. It configures PCI-to-PCI bridges, allocates memory, and provides both single and burst transfer access methods. An EPICS-based server enables remote debugging access to PCI devices, while device-specific methods facilitate control of Local Control FPGA and LRB/LTB. The Python client offers interactive access to detected PCI devices for basic hardware debugging without software development, albeit with slower performance. Documentation is forthcoming.

Presentation Transcript

  1. STT MB Support Package • VxWorks part (C++): • Detects MBs and initializes UniverseII chips • Configures PCI-to-PCI bridges, detects PCI devices and allocates memory for them • Provides PCI single and burst transfer access methods • Provides EPICS-based “server” method which allows slow remote access to the PCI devices (for debugging) • Provides some device-specific methods for the Local Control FPGA and LRB/LTB (as a part of user-implemented “drivers”) • Provides “parser” method as a tool for a language-independent PCI device initialization (under development)

  2. STT MB Support Package • Client part (Python): • Provides an interactive access to all detected PCI devices (single transfers only) • Allows to do basic PCI hardware debugging without any software development • Is very slow (0.2 sec per single read/write command) • Documentation will be available soon.
