C-4 Description of Self-test Test Items
The waveform that the channel transmits is incorrect if the information “Open circuit
emit receive channel: XXX” appears.
The transmission of the channel affects others’ if the information “Open circuit emit
receive channel: XXX” appears.
Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to change CPU if the test result is FAIL.
C.1.9 Z0208 DSP FPGA and EC ARM Interconnection
Test
Top test items
PC Module and DSP FPGA Interconnection Test
Test content
Test whether UART communication between DSP FPGA and EC ARM works well.
Send the data which is written on the register to serial port EC data, and then send
the data of the register from serial port EC data to re-read it. Then, judge the
coherence of the sending data.
Analysis to test failure
The drive goes wrong if the test result appears Error.
UART interconnection between DSP FPGA and EC ARM goes wrong if the test fails.
Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to change CPU if the test result is FAIL.
C.1.10 Z0209 DSP FPGA and SM ARM Interconnection
Test
Top test items
PC Module and DSP FPGA Interconnection Test
Test content
Test whether UART communication between DSP FPGA and SM ARM works well.
Send the order through SM serial port drive, and re-read the data via the serial
port.
Analysis to test failure
The drive goes wrong if the test result appears Error.
UART interconnection between DSP FPGA and SM ARM goes wrong if the test fails.
Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace CPU if the test result is FAIL.
