Error Codes for the Fail Indicator (part 1 of 2)
F AIL I NDICATOR S TATE
[N UMBER OF BLINKS :]
E RROR
Off No error detected
Continuous On Critical: Boot failure; bad code in boot block
Fast blinking Critical: Unanticipated exception prior to relocation of loader code
Fast varying blink Critical: Unanticipated exception after relocation of loader code
1 Critical: SRAM failure
2 Critical: Local register failure
3 Critical: Boot block CRC failure
5 NVRAM error. An error was detected during the NVRAM self-test. This
self-test is performed at every power-cycle, and verifies that the NVRAM
checksum is valid, and also that the data stored is compatible with the
current firmware version. A failure of this test will require an NVRAM Init
command to be issued. Issuing this command will result in all stored
settings being cleared.
6 Self-Test fail. A failure was detected during the commanded self-test (note
that this is different than the power-up self-test). Further information can
be obtained by reading the self-test error status.
7 Operational error. These errors are usually caused by issuing
communication commands with invalid Command IDs, out-of-range data,
invalid slot number, and so on. This error condition is cleared after the Fail
indicator has indicated it.
8 Serial EEPROM Error. A checksum or version error was detected on the
serial EEPROM data. This data stores normalization values.
9 AD Failure. An error (gain out of range or offset out of range) occurred on
at least one A/D, when the A/D gains and offsets were set. The ability to
perform a zero, self-test or shunt tests may be impaired in this state.
Issuing a Cal A/D command may clear this state.
10 Critical: Memory allocation failure
11 Critical: An unexpected interrupt occurred.
12 Communication Interface Init Error. An error occurred while attempting to
initialize the communication interface. The communication interface may
be unusable in this state.
13 TI Firmware Init Error. An error occurred while attempting to initialize the
TI firmware. The communication interface may be unusable in this state.
14 Box ID Error. An error occurred while attempting to initialize the TI Box
ID. The communication interface may be unusable in this state.
15 DAC Init Error. An error occurred while attempting to initialize the TI
DACs. The functionality of the TI may be impaired in this state.
16 Switch Init Error. An error occurred while attempting to initialize the TI
switches. The functionality of the TI may be impaired in this state.
