Pin flash_nCE, nCE0 as I/O

--- Quote Start ---

Hi,

Under Assignments/Device/Device and Pin Options/Dual Purpose Pins

you can configure your Dual Purpose Pins.

But if you are using Quartus 10.0, there is an error in the GUI.

In this case, you have to configure the Dual Purpose Pins by yourself in the

Quartus Setting File.

e.g. "Project_Name.qsf".

Open this File and correct the global assignments for the following Dual Purpose Pins.

set_global_assignment -name CYCLONEII_RESERVE_NCEO_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_DATA0_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_DATA1_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_FLASH_NCE_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_DCLK_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_DATA7_THROUGH_DATA2_AFTER_CONFIGURATION "USE AS REGULAR IO"

set_global_assignment -name RESERVE_OTHER_AP_PINS_AFTER_CONFIGURATION "USE AS REGULAR IO"
