PN7462 OM27462CDKP Development Kit Dynamically Switch Between HIF HSUART and USB

[EE_Ark]

Hi,

We are developing a firmware based on PN7462AU->phExCcid sample.  We will use USB port for communicating with PC through CCID protocol. But we also want to use HIF_HSUART PORT. We want to dynamically switch between two in our firmware.

We are already using USB port for communicating with PC through CCID protocol. Therefore
in 'APP_NxpBuild.h' header file we use '#define NXPBUILD__PHHAL_USB'.

To use HSU '#define NXPBUILD__PHHAL_HIF' should also be added to 'APP_NxpBuild.h' header file.

When we try to use both defines compiler gives us an error : 'HIF and USB can not be combined.'

What should be done to dynamically switch between 'NXPBUILD__PHHAL_HIF' and 'NXPBUILD__PHHAL_USB' in our firmware.

Best regards.

Best regards.
