PN7462 OM27462CDKP Development Kit Dynamically Switch Between HIF HSUART and USB

EE_Ark — Thu, 25 Nov 2021 16:47:57 GMT

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.

Hello,

Unfortunately, There is no the demo for the application. Generally, The customer uses the hardware for the customer.

Please refer to the Table 75. PCR_SYS_REG (address offset 0x0C) of the user manual if you want to use it via software.
