Crown Beach Board

2.5.15In-Target Probe (ITP) and Debug Support

Crown Beach provides on-board ITP support with an XDP connector. Users can debug from the reset vector without EFI or OS dependency (up to OS functionality). Ports 80-83 are provided as a troubleshooting tool to monitor POST output during EFI execution.

Note: ITP requires that the CMC load to configure Poulsbo before register accesses can be made. The CMC code resides in the FWH on Crown Beach. Thus, it is required that the FWH flash be programmed and inserted in the FWH socket to use ITP.

Note: Crown Beach does not support ITP 700.

2.5.16Power Supply Solution

Crown Beach can be powered from an ATX power supply (desktop solution) that contains all of the voltage regulators necessary to power the system up. Additionally, virtual battery support is provided through switch SW8A1.

Note: Use an “ATX12V” 1.1 specification compliant power supply regardless of supplier or wattage level (an "ATX12V" rating means V5 min current =0.1 A, "ATX" V5 min current = 1.0 A, among other differences). For example, the Sparkle Model No. FSP300-60BTV meets this requirement and is an ATX12V 1.1 spec compliant power supply. Depending on the power supply used, Crown Beach may require a load. Crown Beach provides FETS to assist with this loading through jumpers J4J1 and J5J2, see Table 9 for jumper settings.

Note: If the power switch on the ATX power supply is used to shut down the system, wait at least 5 seconds before turning the system on again.

Note: The recommended way to shut down the board is to press and hold the power button switch (SW3J1) for 5 seconds until the power supply turns off. Using the power supply switch or pulling the plug out of the wall is not recommended.

2.5.17Board Size

The reference board form factor is similar to the µATX 9.6 x 10.4 inch (243.84 x

264.16 mm) specification. The back panel jacks may not conform to ATX specifications.

2.5.18Board Technology

The Crown Beach reference board uses fine pitched BGA packages, down to

0.0024 inch (0.6 mm) pitch. Type IV high density-interconnect technology is required for breakout purposes and implemented using a 1-6-1 stack-up (8 layers total).
