TDA8026 Issue

Discussion created by Vageesh Panditharadhya K M on Jan 18, 2017


One of my customer doing IOT POS handheld on AM3354 platform. In the design they used our TDA8026 smart card IC.

The basic communication level I2C bus is Ok and able to probe the tda8026 driver that mean the I2C Read/Write communication is ready.


Whenever they keep Credit card chip in to the smartcard grove which is not sensing any Interrupt (Defined IRQ & SHUTDOWN Pin under device tree) to read the information over I2C.


They are using 2 SAM slots and 1 Smartcard.


Kindly guide me on this.
