my mcu's spi 1 & 2 is not working accordingly.

[shikha]

my device was working properly. but when i enabled lvl 1 RDP protection..all peripheral device connected was still working correctly. but the moment i changed the optional byte to level 0 again n erase the whole flash and reprogrammed it again without enabling ROP protection. then my spi 1 & 2 is not working correctly but rest peripheral is okay.

please help, thanks in advance.
