Programming and Debug
8.1
Has the flash programming connector been
connected to the correct I/O on the microcontroler?
8.2
Has a connector for debug been added that allows
the microcontroler to be put into programming mode?
(RSTN & PIO5/ISP pins)
8.3
Is the reset pin RSTN properly connected?
8.4
Add a test point at an unused DIO in order a trigger
signal can be output from the pin for sensitivity
measurements
8.5
For printed and chip antenna: Is the RF line
implemented in such a way that the HW can be easily
modified in order to do conducted measurements on
one hand and measure the antenna characteristics
on the other hand ? For instance a 0 ohm resistor can
be used to connect the QN9090 RF port to the
antenna for the real application and a SMA or µFL
connector footprint can be added for debug; the SMA
or µFl connector will be connected/disconnected
to/from the QN9090 RF port or the antenna with 0
ohm resistors.
8.6
If I2C used, are the I2C lines pulled up?
9
External Memory
9.1
In case an external flash memory is used has the
correct type of memory been used and is it connected
to the microcontroller correctly?
9.2
Has the flash memory symbol pinning been checked?
