6.1 Errorlog

Explanation:
The application errors will be logged in the NVRAM. The
maximum number of error bytes that will be visible is 16.
The first word (4 digits) of the byte is the component
identification, the last word is the error code.
The diagnostics software will present a combination of this
component identification plus an error code on the local
display (and on the attached terminal). The last reported
error is shown as < 00000000, the oldest visible error as
00000000 > and the errors in between as < 00000000 >.
The devices that may report errors are the serial controller
(UART), the basic engine (BE), the slave processor
(SLPH), the SACD Stream Manager (SSM) and the SACD
Media Access (SMA). The identification of these
components is as follows:
Component name
Serial controller (UART)
Engine (BE)
Slave Processor (SLPH)
SACD Stream Manager
(SSM)
SACD Media Access (SMA)
Diagnostic software (DS)
The tables in the next chapters list the error code and
corresponding problem. The column 'Explanation' holds a
more elaborate description and the most likely reason for
the error.
Some Examples:
002E0000 (SMA reported a timeout error)
0016010A (Engine could not fully close or open the tray)
D0010001 (Flash checksum failed).
For further explanation of DS errors, see description of
nucleui error codes in paragraph 8.

Explanation
To many characters were offered in
too little time. Reason: system was
too busy doing other jobs.
Usually a protocol error. Reason:
bad connection between engine
and processor.
Explanation
Parameter(s) not valid for this
command. Reason: some
communication problem
between UART and engine.
