Hello

Just wanted to know if there are no clock domains issues when connecting Nios running at 100Mhz and Flash controller IP running in a slower speed?

I want to use Remote update and to program serial flash with an application image from Nios.

Flash controller IP currently connected exactly as shown on figure 3 above (to instruction and data master buses of Avalon).

Or I need to connect Nios and Flash controller IP through a bridge?

I am using EP4CGX150CF23C8N.

Thank you

Alex
