168 Neuron Firmware Error Codes
Code Description
151 Write past end of network buffer.
This system error is logged by the Neuron Chip firmware. This run-time
error is checked only in the development environment. The outgoing
application message could not fit into the outgoing network buffer. The
maximum length is 255 bytes.
152 Checksum error over application program.
This error may occur rarely due to Neuron Chip, transceiver, or application
failure.
153 Checksum error over configuration data.
This error may occur rarely due to Neuron Chip, transceiver, or application
failure.
The Neuron Chip retains a checksum of the application program and of the
configuration data. If it is not the correct value, an error is logged, and the
device goes into a blank or unconfigured state. This is usually a hardware
problem, although it could be caused by the application writing over itself.
See the section
Defining Reboot and Integrity Options in Chapter 7 of the
LonBuilder User's Guide for a discussion of checksums and other integrity
features.
154 Transceiver register address out of range.
This system error is logged by the Neuron Chip firmware. This run-time
error is checked only in the development environment. The valid range for
transceiver status information is 1 through 7.
155 Transceiver register operation timeout occurred. *
This error may occur rarely due to Neuron Chip, transceiver, or application
failure. A transceiver hardware failure occurred and the transceiver could
not be configured.
156 Application buffer too small.
This system error is logged by the Neuron Chip firmware. A message was
received into a network buffer but it could not fit into an application buffer.
May need to increase the buffer size with the #pragma app_buf_in_size
directive (see the Compiler Directives chapter in the Neuron C Reference
Guide ).
157 io_in or io_out not ready.
This system error is logged by the Neuron Chip firmware. This run-time
error is checked only in the development environment. Function io_in() or
io_out() invoked for a parallel I/O object when not in the proper state for
input or output, respectively.
