Firmware Error Codes

Code

Description

167

Triac clockedge +- not supported.

This system error is logged by the Neuron Chip firmware. This error is

logged when an application using the triac clockedge plus/minus feature is
loaded into a 3150, which does not support this feature.

168

Checksum error over system image.

This error may occur rarely due to Neuron Chip, transceiver, or application

failure. This error is logged when the device goes application-less following
a checksum error in the system image.

169

Invalid proxy routing table index.

This system error is logged by the Neuron Chip firmware.

170

Invalid version.

This system error is logged by the Neuron Chip firmware. Application was

linked for a different version of firmware than is in the device.

173

io_access() violation.

A call to io_access() occurred when the interrupt service routine (ISR)

context was not scheduled (that is, for the two lowest clock rate settings).
Completing the io_access() call could deadlock the system, so it is ignored

and the error is logged.

174

Stack Collision/Underflow/Overflow.

The data stack and return stack have collided, underflowed, or overflowed.
The system resets, and logs this error after the reset.

175

Illegal opcode executed.

Likely caused by a program crash. The system resets, and logs this error

after the reset.

176

ISR resource violation.

The following operations are not allowed within an interrupt service

routine (ISR):

• Allocation of an outgoing message buffer. The allocation fails.
• NV updates or polls. The setting of the NV “update bit” is denied.
• Any writes to non-volatile memory (NVM). The write operation is

ignored.

177

Breakpoint in an ISR.

The error is logged, and the interrupt service routine (ISR) context resets
the device. After the reset, the error is detected and the device’s state is

changed to hard-offline. The state change prevents a possible endless

repetition of this condition.
