Parity:01 ???

This problem has been addressed before:

Indala produced by lf indala clone --fc --cn produces a different result than lf indala clone --raw. I’m not talking about reading.
I have a Russian TMD-5s device. Entering decimal 171-53672 correctly produces Indala- Parity:01

The reading is correct. Writing with --fc --cn doesn’t work properly. Writing with --raw works fine.

Yeah that’s odd. Feels like either a read/write error or a pm3 firmware bug.

Have you tried multiple writes and reads to confirm?

Everything works fine. RAW is incorrectly generated for FC 171 CN 53672. Parity 11, should be 01 - lf indala clone --fc 171 --cn 53672…Preparing to clone Indala 64 bit to T55x7 raw A0000000A7AE90E1 ----it should be like this raw a000000087ae90e1. For - lf indala clone --raw a000000087ae90e1 everything is ok… Parity 01
