4.6 Troubleshooting
This section provides guidance in troubleshooting SENtral, and is divided into hardware-
related and software-related errors.
4.6.1 Hardware-Related Error Conditions
Possible indications of a hardware-related problem are given below in Table 4-7.
Table 4-7: Hardware-Related Error Indications
Register Name Address Error Indication
EventStatus 0x35
[0] 1 = CPURest. SENtral Configuration
File needs uploading. See Section 4.1.
SentralStatus 0x37
[2] 1 = EEUploadError. Issue with
uploading from the dedicated EEPROM.
See Section 4.1.
MagRate 0x55 0x00 – Value lost
AccelRate 0x56 0x00 – Value lost
GyroRate 0x57 0x00 – Value lost
In the event of such errors, SENtral will enter Standby State, shut down the sensors, and
generate an interrupt to the host. Possible reasons for hardware-related errors include
problems with the EEPROM upload, power transients detected by power management,
and errors in software detected by Watchdog. Often the error can be cleared by sending
the ResetReq command.
