Why does system hang when I set CE_PA22 as high leve? Does LBC multiplexed GPIO pins can not be used as GPIO when LBC is enabled?

Hello,

 

Why does system hang when I set CE_PA22 as high leve or low level?

 

In my platform, we use NOR flash with the LBC cs0, meanwhile, we want to use CE_PA22 as an output GPIO, 

but when I set CE_PA22 as high level, system will hang, when set as low level, also will hang.

 

Could please help to give some suggestions?

 

Thank you,

Carl
