Test Sequence
This section describes the sequence of steps involved for the DA1470x device testing. It outlines all
the steps the PLT follows to successfully test a device.
6.8.1
DA1470x Test Sequence
describes each step that the PLT undertakes to validate and program DA1470x-based
devices. Some of the steps are optional and will only be executed if the equivalent actions are
enabled in the configuration parameters.
The entire test sequence for the DA1470x DUTs is shown in
Table 14: DA1470x Test Sequence
Step
Action
Opt. Description
1
Statistics update
No
Update the total tests executed.
2
BD addresses
No
Update the BD addresses for all DUTs.
3
Configuration parameters
No
Configuration parameters are passed from the CLI or
GUI to the
prod_line_tool_dll.dll.
If any of the
parameters is not valid, an error will occur.
4
Reset GU
No
GU hardware reset by controlling an FT232 pin.
5
Initialize PLT hardware (CPLD)
No
The GU will set the CPLD to an initial known state.
6
Check temperature sensor
instrument
Yes
Check whether the temperature measurement
instrument is online, only if the temperature
measurement test is active.
7
Check Bluetooth
®
LE tester
instrument
Yes
Check whether the Bluetooth
®
LE tester instrument is
online, only if any of the Bluetooth
®
LE tester test
operations is active.
8
Check ammeter instrument
Yes
Check whether the ammeter is online, only if any of the
current measurement tests is active.
9
Toggle GU LED
No
Toggle the GU red LED on the PLT hardware to
indicate that the GU is alive.
10
Check DUT COM ports
No
Check whether the PLT has identified the DUT COM
ports and if not run the automatic DUT COM port
identification.
11
Temperature measure
Yes
If the temperature measurement test is active, take a
measurement and log it to all DUT logs and in the CSV
file.
12
Power-up DUTs
Yes
Provide power to the DUTs so the boot process can
start.
13
Download
uartboot_da1470x.bin
Yes
If any of the production tests is active the
uartboot_da1470x.bin
will be downloaded so
st_da1470x.bin
can be downloaded to the system
RAM. In addition, if the GPIO watchdog option is
enabled, it will start toggling after the
uartboot_da1470x.bin
is loaded and right before the
production test download.
14
Get
uartboot_da1470x.bin
version.
Yes
After
uartboot_da1470x.bin
has been downloaded,
commands can be sent to it. A command to get the
uartboot_da1470x.bin
firmware version is sent to the
devices.
