hi all,
i found that serial flash loader allows epcsx to be configured through jtag, i would like to know how to instantiate the sfl image to the user design using sfl megafunctionForum Discussion

Altera_ForumSimply include the SFL instance to your top level design.

but how to control the ASMI access granted and ASMI access request signals of the mega function

You don't them, unless you don't have other connections of your design to the AS memory. A typical instantiation looks like this:
sfl_inst : sfl PORT MAP ( noe_in => '0' ); - Altera_Forum
how should be the ASinterface connections and nCONFIG connection to fpga while configuring EPCSx via SFL image
- Altera_Forum
It's all in the device manuals, e.g. figure 10–30. programming serial configuration devices in-system using the jtag interface for Cyclone III.

I have ASMI connections to EPCS.Int his case,how do I connect(instantiate) SFL?
sfl_inst : SFL PORT MAP ( asdo_in => asmi_access_granted => dclk_in => ncso_in => noe_in => asmi_access_request => data0_out => ); - Altera_Forum
I have ASMI block in my design.In this case,how do I connect other pins?
Isee following errors when I disable Share ASMI interface option. Error: Pins ALTERA_DCLK both have the SPI-related DCLK Pin assignment, but only one pin can have this assignment Error: Pins ALTERA_SCE both have the SPI-related SCE Pin assignment, but only one pin can have this assignment Error: Pins ALTERA_SDO both have the SPI-related SDO Pin assignment, but only one pin can have this assignment Error: Pins ALTERA_DATA0 and ALTERA_DATA0 both have the SPI-related Data[0] Pin assignment, but only one pin can have this assignment
