I have been trying to get my PN532 NFC module to work using either I2C or SPI but neither way is working.
I have followed the instructions from the manufacturer (http://wiki.sunfounder.cc/index.php?title=PN532_NFC_Module_for_Raspberry_Pi) for both I2C and SPI and originally through I2C wasn't getting communication (their chart for connection was off) but eventually got the cabling all correct - but this resulted in the following error;
nfc-list: ERROR: Unable to open NFC device: pn532_i2c:/dev/i2c-1
So I tried SPI and got to the same testing;
nfc-list: ERROR: Unable to open NFC device: pn532_spi:/dev/spidev0.0:280000
I get part one of SPI instructions 7. (If two devices are detected, it means the SPI is already opened.) so should just be able to go ahead with nfc-list, but keep getting the above error.
I have tried trouble shooting using this chat (ITEAD PN532 on Pi 3 with libnfc) but all of the external links they used to provide full instructions as to what they did no longer work - so therefor can't actually use the troubleshooting because they don't explain it fully.
Would love any help that could be provided.
