Diagnostic Software
Get the device (revision) type information of the 1394 Physical layer IC
- Initialise the PIO pins of the Codec-Write the PHY
- access register in the Link chip to indicate phy read access
- Wait until the link chip has obtained the value from the phy-chip
- Read this out and filter the data to be returned to the user
Less than 1 second
None
DS:> 701
070100: Physical layer IC: VendorID: 0x006037, ProductID: 0x412801
Test OK @
DS_DVIO_LinkCommunication
702
Check the accessibility of the 1394 Link layer IC by writing to and reading from a specific
address
- Initialise the PIO pins of the chrysalis
- Write a pattern to the CYCTM register of the link chip
- Read back and verify the pattern
Less than 1 second
None
Number Description
70200 Communicating with the link layer IC succeeded
70201 Communicating with the link layer IC failed
70202 Result of nucleus not according to HW diversity string

Test OK @
DS_DVIO_PhyCommunication
703
Check the accessibility of the 1394 Physical layer IC by writing to and reading from a spe-
cific address
- Initialise the PIO pins of the Codec
- Initialise IIC
- Write the data to be written to the phy-chip to the link chip first
- Wait until the link chip indicates that the data has been written to the PHY
- Write the PHY-access register in the Link chip to indicate PHY read access
- Wait until the link chip has obtained the value from the PHY-chip
- Test whether the value read back equals the one previously written
Less than 1 second
None
Number Description
70300 Communicating with the physical layer IC succeeded
70301 The physical layer IC was not accessible
70302 Communicating with the physical layer IC failed
70303 Result of nucleus not according to HW diversity string
DS:> 703

Test OK @
DS_DVIO_Routing
704
Route a DV stream containing an audio and video signal through the physical and link layer
ICs to the Codec. This test works for both NTSC and PAL.
- Initialise the DMA to transfer 5 frames PAL/NTSC
- Initialise the DV demultiplexer
- Initialise the 1394 interface and start reception of the DV stream
- Check whether the stream was copied to memory properly by the byte input interface
(port to memory type DMA)
6-10 seconds (6 when OK, 10 when no stream or error)
None
