Note: The related timings and current consumptions during the ping, as needed for
the estimation of the overall average current consumption, are defined in: c:\nxp
\NxpNfcCockpit_v4.6.1.0\cfg\NxpNfcCockpit_Configuration.ini
Note: The LPCD requires a stable TVDD, otherwise the AGC value is not stable and
the PN5180 wakes up easily. So, for standard USB only operation (no external power
supply) it is recommended to use
a) a higher gear number (which reduces ITVDD and TVDD ripple)
b) a longer RFON time (which stabilizes the TVDD)
Note: The LPCD mode disconnects the PN5180 from the LPC (to save power), so
the LPCD mode can only be left, if either a card loads the antenna and wakes up the
PN5180, or the LPC resets the PN5180.
4.10 Secondary FW and EMVCo Loopback application
The Secondary Firmware tab allows to flash another secondary FW. The secondary FW
of the LPC handles the communication between the NFC Cockpit and the PN5180. The
secondary FW might contain additional applications, which can then be started via the
Secondary Firmware tab.
The default applications are:
EMVCo Loopback: Test function for EMVCo test
Transaction Send A: Test function for EMVco test
Transaction Send B: Test function for EMVco test
The EMVco Loopback (or other application) can be started by pressing the <Start
Secondary Firmware> button, and then is executed on the LPC. The function can be
stopped by pressing the <Stop Secondary Firmware> button, but afterwards the PN5180
must be reset to continue with the standard NFC Cockpit functionality.
