STARTER KIT REFERENCE MANUAL
Lassen DR + GPS Reference Manual 114
Fatal errors indicate abnormal operation of the module. In general these errors
(such as illegal address) are not recoverable. Under these conditions, the
receiver writes to the log first, and then sends an event packet to notify user
before it restarts (warm or cold reset). The fatal errors are divided based on the
source of error:
1. Interrupt system errors have a high byte of 0x10. The low byte is the
vector number at fault.
2. Hardware-related system error, e.g. RAM, ROM, or gyro, has a high byte
of 0x12 or 0x13.
3. RTOS events (errors related to the Operating System related function
calls) have a high byte of 0x20.
4. Navigation library events and run-time positioning diagnostics have a high
byte of 0x40.
Hard Reset means “Clear RAM and Reset SW”. The column “Ver” indicates
which ROM versions have this fatal error code feature.
