Hi,

I am using the PN7462AU controller for NFC data transfer. I have downloaded firmware at 0x20A000 instead of 0x203000. After that I am trying to flash code at 0x203000 it is generating an error every time. I have tried erasing flash also but no success. This happens on two separate boards so the issue is critical. 

Thanks, Jayesh.

Hi Jayesh,

 

Hope you are doing well. Could you please try to update the flash via USB Mass Storage Device interface? Section 8.10 of this User Manual.

 

Hope this helps.

 

Best Regards,

Ricardo
