Hi,
I want to calculate CRC with hardware CRC but polynomial on the register is work on 32 bits.Can possible to calculate CRC 8-bits with hardware in the MCU? And how?Or I have to use sw crc.Thank everyone.

The newer F3 and F072 parts support a programmable CRC peripheral, the F4 has a fixed width, polynomial, direction, reset, and bit/endian setting and is significantly less applicable to other applications.
If I knew the polynomial you're looking at and some data test patterns, I could probably help you with that.

Thank, waclawek.jan and clive1
I have to use vary polynomial. This function will be common modules of projectI might use software crc.
