Linux / Android CCID driver for PN5xx

c_adharumaraj — Mon, 20 Jan 2020 06:21:13 GMT

We are using a PN553 NFC on a snapdragon board running Android Pie. The PN553 is connected to the main controller through I2C. We are trying to implement a CCID driver for the PN553. We could not find any open source implementations for a CCID driver over I2C.

Does anyone know of any references for CCID driver over I2c for PN5xx?

What about PN553? Does it support CCID?
