pn532 key corruption

by heliumface770 on Sat Aug 01, 2020 2:47 pm

I used the pn532 to format a mifare classic 1k to ndef, and now sector (block?) 0 of the tag can't be authenticated. I tweaked the memdump sketch and am still able to write and read from sectors 1 - 15, but I can't authenticate sector 0. I guess it's not really a problem, since functionality isn't hindered outside of no longer being able to use the provided examples without modification. I guess I'm more curious what happened, and how common this sort of thing is.

Since posting this yesterday a second tag has been corrupted in the same way.
