[AMa]

Hi,

If need operation Configuration Flash during user mode, how to set it? On Device and Pin option page, just have DATA 5- DATA32 can set to regular I/O, the DATA0-4 how to operation it?

I had trid to constraint DATA0-DATA4 in Pin Planner page, but it will have some error.

Hi Xiao Min,

You will need to use Serial Flash Mailbox IP to interact with flash during user mode.
