Once all the steps mentioned in the Android porting document(https://www.nxp.com/docs/en/application-note/AN11690.pdf) is completed, the test application NfcFactoryTestApp doesn't work properly. NFC option is available in the settings window, but when its turned ON , dmesg shows the following error

 

pn54x_dev_write : i2c_master_send returned -107i2c-msm-v2 7575000.i2c : NACK: slave not responding, ensure its powered: 
msgs
(n:1 cur:0 tx) bc(rx:0 tx:4) mode:FIFO slv_addr:0x28 MSTR_STS:0x0d1300c8 OPER:0x00000090

Definition added in platform tree file is as follows

&i2c_8 {        
pn547
: pn547@28 {              
      compatible
= "nxp,pn547";              
       reg
= <0x28>;               
       clock
-frequency = <400000>;          
       interrupt
-parent = <&tlmm>;     
       interrupt
-gpios = <&tlmm 10 0>;
       enable-gpios = <&tlmm 11 0>;
      
};
};

Any help will be appreciated.
