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

Please specify what you exactly doing in terms of hardware - i.e. which address locations you are writing, and with this values exactly.

Have a great day,
Alexander
