nfc spi and other i2c

[cyberfly79]

Hello Robin, I found a bug? I use more i2c sensors. I2c's sonsors are working, until I don't use the nfc. If I use this (./explore-nfc poll - it's ok), then i2cdetect said: i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30: 30 31 32 33 34 35 36 37 38 39 3a UU 3c 3d 3e 3f 40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 60: 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f 70: 70 71 72 73 74 75 76 77

and, the i2c aren't working :( I removed the pin3 and pin5 (i2c), after the reading i2c is not good... :(

Have you an idea?

Thanks!

Hi, I'm sorry I won't be able to help, I don't know anything about i2c. explore-nfc poll just write on the stdout the bytes it reads from the card.

Note that I didn't wrote the underlying driver (code inside NxpRdLib_PublicRelease). The bug you describe seems to have something to do with low level code. This is code from NXP.

Sorry I can't help more, let me know if you find a solution

Did you get any feedback from NXP regarding this issue ? I just get exactly the same trouble, and NXP never answer to our request ... :((

Hi all, any fix or workaround regarding this issue, i want to use an i2c 2x16 lcd and the nfc board but the i2c is not detected anymore.
