AWR1843BOOST: AWR1843: CBUFF, LVDS CRC Format?

Part Number: AWR1843BOOST

Hello.

CBUFF_InitCfg structure contains parameter ".u.lvdsCfg.crcEnable".
If crcEnable=1, what parameters (generator polynomial/Init Value) of CRC algorithm will be implemented?

This section does not contain specific algorithm of CRC settings for the LVDS interface.

Thank you for checking.

I will loop in the LVDS expert to check if there is additional documentation regarding CRC in LVDS

thank you

Hello Alex,
The 32-bit polynomial is CRC-32 (similar to the ethernet) t: G(x) = x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1

Regards,
Vivek
