Hi salugu,

the demos as is are running and reading NFC-V tags. So the default delivered binaries should work, do they? Did you port it to a different MCU? Any other changes? In case this happens only after porting - please provide logic analyzer traces.

The no response interrupt is normal when there is no tag. Even in case the tag is there this error may still happen depending on the command sent.
