About EMVCo L1 reset test

[SeanHu]

Hi expert,

We encountered some abnormal responses when running the EMVCo L1 test project TAB113 (Reset Test) using a PN722x.

We tried inputs of 0x20, 0x00, 0x01, 0x01 and 0x20, 0x00, 0x01, 0x00, but the results were unsatisfactory.

Could you please provide the NCI commands for this reset test project? Or do you have any suggestions for this test project?

Thank you.

Hi Jimmy,

I followed the data sheet to issue LOAD_RF_CONFIG_CMD : 0x2F, 0x0E, 0x02, 0xFF, 0xFF. And I got following response : 0x4E, 0x0E, 0x01, 0x00.

And then I issued the SWITCH_RF_FIELD_CMF : 0x2F, 0x3F, 0x03, 0x32, 0x02, 0x00. And I got following response : 0x4F, 0x3F, 0x01, 0xF3, which indicate that "Invalid Load RF Configuration - LOAD_RF_CONFIG_CMD needs to be successful".

But from the previous command response, the LOAD_RF_CONFIG_CM was return "STATUS OK"

Do you have any suggestions for this unsuccessful response?

Hi Jimmy,

I follow the 14.7 SWITCH_RF_FIELD_CMD in  PN722X NFC controller , I add a function in kernel driver which writes {0x2F, 0x3F, 0x03, 0x32, 0x02, 0x00} to PN7220. The test result still failed.

I upload the test log for your referenct, do you have any comment on this error?

Thank you.

Your CMD is CORE RESET. I think the TAB113 is the RF Reset test.

Hi Jimmy,

Yes, we need a command to do RF Reset test. 

Can you provide me NCI command to do the RF reset?

Thank you.

Please check the 14.7 SWITCH_RF_FIELD_CMD in  PN722X NFC controller

Hi Jimmy,

Could you explain to me the purpose of payload field  "Field On Config" ?

I don't understand the meaning of "Use collision avoidance" and "Disable collision avoidance".
Thank you.
