PN7462 Debugging Error in MCUXpresso IDE – Need Root Cause and Resolution

Vignesh_Venkatesan123 — Tue, 19 May 2026 07:08:19 GMT

Hello All,

I am using the PN7462 Development Kit with MCUXpresso IDE version 12.24.148. While attempting to debug code on the PN7462, I am encountering the error shown below.

I have included the debug log and attached a screenshot of the error for your reference.

Could you please help identify the root cause of this issue and suggest a possible solution?

Thank you in advance for your support.

Hello @Vignesh_Venkatesan123

Try turning the power off and then on again. In principle, EVK+example project should not have any problems. It works on my side.

Hello KaiLi,

I am working on below example code "NfcrdlibEx10_MIFAREDESFire_EVx". I could able to progress for certificate read/write and flash. Now i am facing this issue in board side. there are no changes made to SW which worked earlier.

Probe used : LPC-LINK2 CMSIS-DAP V5.224

Best regards,

Hello @Vignesh_Venkatesan123

Please try updating the LPC-Link2 firmware. Normally, the EVK board and software code haven't been modified, so there shouldn't be any problems.

Please update firmware by going LPC-Link2 | NXP Semiconductors

There is no problem with LPC-Link2. As i connected another EVK board with the same LPC-Link2 and same probe, debug flashing is happening properly. Problem is with EVK board.

Hi @KaiLi

Can you please explain the process of how to do full erase ?
