5.4 Functional Verification with Assem-
bled Module
Attention: If a fault is discovered, consider the impact of the issue observed
on all manufactured samples.
The purpose of this section is to validate the assembly process of the module.
This test covers:
1. VZM20Q pins and features:
a) Power supply
b) UART1 console output during power-up operation
c) SIM Interface
d) GPIOs
2. Nominal power consumption
3. VZM20Q boot
5.4.1 Power Supply
5.4.1.1 Procedure
1. Turn on the device under test in FFH mode.
2. Confirm voltages of the power supplies remain the same before VZM20Q
is assembled.
Caution: If, at this point, the voltages are incorrect, stop immediately
to diagnose the cause of the issue.
3. Confirm that the current is nominal from the internal power supply
Observe the current drawn and ensure it is in line with the expected one.
a) Expected VZM20Q current with no firmware loaded will be provided
in a future revision of this document.
