Step
Action
Opt. Description
15
GPIO watchdog
Yes
If the GPIO watchdog option is enabled, then firmware
will start the toggling after the
uartboot_da1470x.bin
is
loaded and right before the production test download.
16
Download
st_da1470x.bin
Yes
If any of the production tests is active (e.g., RF tests,
XTAL trim, etc.) download the
st_da1470x.bin
to the
devices.
17
Open the devices COM ports and
get the
st_da1470x.bin
firmware
version
Yes
After
st_da1470x.bin
has been downloaded,
commands can be sent to it. First, the Windows DUTs
COM ports are opened. Then, a command to get the
st_da1470x.bin
firmware version is sent to the
devices. If there is a problem in the firmware or in the
device, then this is the first failure to happen. The FW
version get action will fail.
18
GPIO watchdog
Yes
If the GPIO watchdog option is enabled, the firmware
will begin a periodic GPIO toggling during the whole
production test procedure.
19
OTP timestamp
Yes
PLT will read the IC production timestamp and log it.
20
VBAT level measure
Yes
PLT will send a command to each DUT to measure
VBAT for each one, using the internal ADC. VBAT level
will be logged for debugging purposes.
21
External 32kHz
Yes
Check whether the external 32kHz crystal operates
correctly.
22
XTAL trim
Yes
Perform the XTAL trim procedure if this is active.
23
UART resync
Yes
If the XTAL trim procedure was performed in the UART
RX pin, then a special UART resync procedure takes
place to resynchronize the device's UART RX path as it
may have entered in a baud rate error state due to the
500ms received XTAL trim pulse.
24
Bluetooth
®
LE scan (TX test)
Yes
If the Scan DUT Advertise test is active, then perform a
Bluetooth
®
LE scan test using HCI triggered
advertisements. DUTs will start to advertise with a well-
known BD address, one by one. GU will scan and
return the RSSI for each DUT.
25
Bluetooth
®
LE tester TX power
Yes
If the Bluetooth
®
LE tester TX Power test is active, then
perform the test using the external Bluetooth
®
LE tester
instrument.
26
Bluetooth
®
LE tester TX carrier
offset
Yes
If the Bluetooth
®
LE tester TX carrier offset test is
active, then perform the test using the external
Bluetooth
®
LE tester instrument.
27
Bluetooth
®
LE tester TX
modulation index
Yes
If the Bluetooth
®
LE tester TX modulation index test is
active, then perform the test using the external
Bluetooth
®
LE tester instrument.
28
Bluetooth
®
LE tester RSSI
Yes
If the Bluetooth
®
LE tester RSSI test is active, then
perform the test using the external Bluetooth
®
LE tester
instrument.
29
GU RSSI test
Yes
If the RSSI test using the GU as transmitter is active,
then perform the test.
30
GPIO/LED
Yes
Perform the GPIO/LED test, if the test is active.
31
GPIO connection test
Yes
Perform a GPIO continuity or voltage level test if the
test is active.
