Description of Self Test Items C-5
◼ Suggestion to failure test
Check whether the connection of wireless network adaptor is fixed well and wireless network
adaptor is not forbidden if the information “No wireless device found” appears.
Check whether there is WIFI hotspot if the information “WIFI Function test FAIL” appears. If there
is a hotspot, replace the wireless network adaptor.
C.1.11 Z0301 Front End Voltage Monitor Test
◼ Top test item
MF FPGA and system monitor interconnection test
◼ Test content
Read A12_ACDC, DP3V3, AP2V1, DP5V, AP5V7, N12V, N5V7, AP2V9, STB5V, AP3V8 on
DC-DC board and AP1V4’s voltage value via ADT7462, and decide whether they meet the
requirements.
◼ 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 DC-DC board if the test result is FAIL.
C.1.12 Z0401 DSP FPGA and TRA Interconnection Test
(Control Interface)
◼ Top test item
PC module and DSP FPGA interconnection test
◼ Test content
Test whether the control interface communication between DSP FPGA and XCVER of TRA FPGA
works well via reading the register.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The connection error between DSP FPGA and TRA FPGA occurs if the test result is 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 change TRA board if the test result is FAIL.
C.1.13 Z0402 TRA AFE SPI Interface Test
◼ Top test item
DSP FPGA and TRA FPGA communication self test (control interface)
◼ Test content
Test whether the control interface communication between TRA FPGA and AFE’s SPI works well
via reading the register.
