Description of Self Test Items C-5
C.1.4 ADC Pressure Test
Top test item
Communication test between MF FPGA and System Monitoring chip.
Test content
The program reads the voltage values of VRTC, DDR_VPP, VDD2V5, VDD1V8, and NVCC and
checks whether they are within the specified range.
Analysis to test failure
As long as one of the above voltages does not meet the specification, the test will fail. If the test
fails, it indicates that there is a problem with the key voltage on the board and the board may be
faulty.
Suggestion to failure test
It is recommended to replace PC carrier board if the test result appears FAIL.
C.1.5 Back End Voltage Monitor Test
Top test item
MF FPGA and system monitor interconnection test
Test content
Read VCC5V, VDD1V8, VDD2V5, VDD1V2, VDDN5V7 and voltage value of button battery via
ADT7462, and decide whether it meets the requirement.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The voltage value does not meet the requirement if the test result appears FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace button battery if VDDBAT voltage appears FAIL.
It is recommended to replace the PC carrier board if the other voltages appear FAIL.
C.1.6 System Temperature Test
Top test item
MF FPGA and system monitor interconnection test
Test content
Read temperature values of PCT1, PCT2 and PCT3 via ADT7462 drive and read temperature
values of four CPUs via bottom drive. Decide whether they meet the requirements.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The temperature value does not meet the requirement if the test result appears FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to check the fan condition first and then replace PC module or PC carrier board
if the test result is FAIL.
