NTag21x signature verification.

[rob_davidson]

Hi,

I work for a company called Spinnaker International, we are UK based. Our website is as follows:-

Secure Innovation | Spinnaker International Ltd 

I have been accepted by the NXP docstore NDA procedure and I have been able to download AN11350. I am only interested in the signature verification function of NTag21x tags. I am using a Microchip PIC24FJ128GB204 microcontroller, I can get the AN11350 8 bit libraries to compile in my 16 bit IDE but I cannot get the ECDSA verify function to give the correct reply even though I am giving it the correct input. Could you please help?

Kind regards,

Rob Davidson.

Hello,

As mentioned in the case, we do not have any way to test it for your specific MCU, we recommend to please follow the instructions in the App Note minutely.
