PNEV5190B does not work

Miyazaki001 — Wed, 05 Aug 2026 08:53:26 GMT

After loading Nfcrdlib_SimplifiedAPI_EMVCo_Secondary.nnc.bin from the "Load Secondary Firmware" option on the Extra tab of NFC Cockpit, my PNEV5190B no longer responds and cannot be operated from NFC Cockpit.

According to the update log, the firmware download completed successfully without any reported errors. The board became unresponsive only after the update was finished.

I found a similar issue in this thread, but I would like to understand the root cause.

What could cause the board to become unresponsive even though the firmware update completed successfully?
Is it possible that I used an incorrect secondary firmware image for my board or firmware version?
Why does loading the secondary firmware result in a state where NFC Cockpit can no longer communicate with the board?

Thank you for your support.

Hello @Miyazaki001

Hope you are doing well.

Could you please provide more details on your setup? What is the procedure you are following?

I tried the following setup:
- PNEV5190B
- FW v2.0B
- NFC Cockpit v9.0.0
- "Extra" tab > "Secondary FW" tab > Load Secondary Firmware
- Select NxpNfcCockpit_v9.0.0.0\firmware\Secondary_PN5190\K8x\Nfcrdlib_SimplifiedAPI_EMVCo_Secondary.nnc.bin

NFC Cockpit should indicate to close the COM port and open it again:

After reopening the COM port, you should be able to start the Secondary Firmware in "Extra" tab.

Regards,
Eduardo.
