EN 33 3139 785 31532 5. Firmware Upgrading & Diagnostic Software
Nucleus Name DS_DVIO_PhyCommunication
Nucleus Number 703
Description Check the accessibility of the 1394 Physical layer IC by writing to and reading
from a specific address
Technical - 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
Execution Time Less than 1 second
User Input None
Error 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
Example DS:> 703
070300:
Test OK @
Nucleus Name DS_DVIO_Routing
Nucleus Number 704
Description 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.
Technical - Initialise the DMA to transfer 5 frames PAL/NTSC
- Initialise the DV de-multiplexer
- 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)
Execution Time 6-10 seconds (6 when OK, 10 when no stream or error)
User Input None
Error Number Description
70400 Routing the signals succeeded
70401 The 1394 link chip could not be initialised properly
70402 There was a syntax error in the DV stream
70403 DMA could not copy DV stream to memory. Stream connected?
70404 DMA not working properly
Example DS:> 704
070400:
Test OK @
Nucleus Name DS_DVIO_DetectNode
Nucleus Number 705
Description Check whether a DV node can be detected by the hardware. This test works for
both NTSC and PAL.
Technical - Initialise the 1394 interface
-
Detect whether a node is in range
Execution Time 3 or 5 seconds (3 when OK, 5 when no stream or error)
User Input None
Error Number Description
70500 The node was detected OK
70501 The 1394 link chip could not be initialised properly
70502 Unable to write to 1394 PHY chip
70503 Unable to read from 1394 PHY chip
70504 No node was detected
Example DS:> 705
070500:
Test OK @
