Preferred Test Strategy for PCI 9054 Interface
NOTE: This only applies to systems with the SCB, EQ and BMP boards configuration. This does not 
apply to systems with EBM Boards.
Several LOGIQ™ 9 circuit boards utilize the PCI 9054 PCI Bus Master I/O Accelerator chip. This section 
defines a common testing strategy for a PCI interface implemented with...

The following accesses to the VPD functionality must be performed with Configuration Reads/Writes.
Given the reserved diagnostic location in the VPD:
1.) Write the Lword 0x7856 3412 to the VPD location. 
2.) Next, read back the entire Lword, and note its value, even if its not what was written.

Preferred Test Strategy for Memory
It is desirable to have a uniform memory testing strategy across the entire platform. This section defines 
a common testing strategy for on-board memory. Deviation from this strategy may be required or 
preferable in some circumstances. When this is the case, the diagnostics SDD must note the deviation.
The three...

7-9-1-3 Strategy for Testing the Internal Memory Cells
To test the internal memory cells, start at the base address and fill the memory with an alternating 
pattern of:
0x55555555
0xAAAAAAAA
0x55555555
...
(masked appropriately)
Read and verify the data. Repeat this, filling the memory with an alternating pattern of:

7-9-1-5 Strategy for Testing Multiple-Part RAMs
Special consideration must be paid to the data patterns written to a RAM that is implemented with more 
than one parts. For example, consider a 32-bit wide RAM that is implemented with 8 4-bit wide parts. 
For this RAM, the test data pattern width must be considered to be 4 bits wide and repeated on all eight...

With the ScFpApiTest active, push a button on the keyboard. A readout of the button id number and the 
indication that it was pushed and released (1 and 0) will appear in the Log area as shown in Figure 7-38.
The button id list is not available. The id number of the button is not important. What is important is the 
fact that a...

Test slide pots (TGC) by moving them through their range. Feedback will be returned to the Log area 
as shown in Figure 7-40.
The important thing to watch here is the slide pot number that is moving and ensure that it’s value 
changes. In Figure 7-40 slide pot s0 is changing.
NOTE: It is important to remember that the trackball and alpha-numeric keyboard are not tested by...
