Hi,
on my board there is a pic uController and a ep4ce6 fpga (with epcs4 flash attached).
They communicate with spi interface.
The uC is the master and fpga is the slave.
When i want to change something in vhdl design i change epcs4 image through uC SPI interface because pins used (DCLK,Data,ASDO and Flash_nCSE/nCSO) by FPGA to program itself from epcs flash, at board's startup, becomes general purpose pins after device configuration is complete.

With this method i can update fpga by uC but i have to turn off and on again the board power supply in order to reconfigure in right way the fpga.

I want to implement a remote update method using IP core ALTERA_REMOTE but i don't need a factory and application image, i simply want to change the boot image and reconfigure fpga from uC dedicated command (internal register).

Is it possible to use only the signal reconfig in ALTERA_REMOTE ip and not watchdog etc... to reconfigure the fpga? I need to manage other IP input signals?

Let me know.
 

If you have a µC connected to the FPGA, you can simply pull down NCONFIG line to cause a reboot after updating the EPCS flash and don't need ALT_REMOTE IP.

Nevertheless it's possible to use the ALT_REMOTE reconfig command if you want to trigger it from the FPGA logic.
