PNEV7462C NFC Cockpit, no VCOM connection

[Pel]

Hi team,

I recently bought a PNEV7462C Demo Kit and while following the user manual UM10883 directive, I couldn't  connect my board to the NFC Cockpit (section 6). NFC Cockpit can't find my board (no VCOM  appear in the bottom left). When I check the device functions on my pc I only see the smartcard reader (WUDF) and no USB or VCOM.

Thanks for your time,

Alexandre Pellerin.

Hi NXP Team,

I downgraded the NXP NFC Cockpit version to 4.8.0 and load the EEPROM and flash associated with the version. Now I can connect to the PNEV7462C board, but seems to have some problems with the NTAG and ICODE protocol cards.

Unfortunately I can't seems to communicate with the other protocol, I can't activate the layer 4 with the NTAG card and the layer 3 with the ICODE card (see NTAG-erros.png and ICODE-errors.png for log monitor view).

Is this a normal behavior for the v4.8.0 ?

I would like to use the Cockpit to read NTAGs  is this possible ?

Thanks again,

Alexandre Pellerin.

Hello,

Thanks for your updated information. This tag does not support Layer 4 operations. Layer 4 is supported by Mifare DESFire tag.

ICODE card please use  the ISO-15693 tab and launching the "Inventory" command..

Have a nice day.

Hi Fangfang,

Thank you for responding quickly. I tried updating the flash and EEPROM 2 times, but unfortunately no success. I can see the PN7462AU now , but still can't connect to it. The 2 times gave me different error, 1st is a HAL error and 2nd is an access denied error (you can fin screen of the log monitor attach as png).

The first time I had jumper on the ATX_A and ATX_B and the second without any jumper on the ATXs.

I'm using the NFC Cockpit version 6.3.0.

Have a nice day,

Alexandre Pellerin.
