C-22 Description of Self Test Items
◼ Test content
The program decides whether ECG is in the place, sends orders via ECG serial port, judges the
returned data, and parses Bootloader version, board ID and software version.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
ECG board is not in the place if the information “ECG board is not in the place” appears or the
circuit is not in the place.
The communication between ECG board and main board goes wrong if the information “Failed to
read the data on ECG board”.
◼ 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 ECG board if the test result is FAIL.
C.1.48 Z1502 ECG Board Self Test
◼ Top test item
Communication test between DSP FPGA and ECG board.
◼ Test content
ECG sends self test order via ECG serial port when it is in the place and analyzes the self test
result, and decides the status for A/D, Flash, DRAM, CPU, Watchdog, Voltage 33.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
ECG board goes wrong 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 replace ECG board if the test result is FAIL.
C.1.49 Z1601 MF FPGA and SM ARM Interconnection Test
◼ Top test item
Communication self test between PC Module and MF FPGA
◼ Test content
Test whether UART communication between MF FPGA and battery management 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 MF FPGA and battery management’s ARM goes wrong if the test
fails.
◼ 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 the battery management board if the test result is FAIL.
