NIOS2 & EPCS16 -SOS!

Altera_Forum · ‎01-05-2005

Hi all.

At my Altera Cyclone development board I design project with EPCS4 - and all work

Now i have build custom NIOS2 board with Cyclone - EPC6

And for Program Code and Hadrware image I use new EPCS16 Active serial flash to increase room for program code

But when i try to configure it from IDE!!!

I saw that EPCS16 IS NOT SUPPORTED!!!!!!!!!!!!!!!!

Because in purpose configuration system used old asmi controller !!!!!!!!!!

that is not fair - in all pdf's i read that is possible to use any EPCS controller

BUT IN FACT NO ONLY EPCS1 & EPCS4!!!!!

Look what IDE tell's me :

Jan 5, 2005 2:40:24 PM - (INFO) nios2-flash-programmer: Launching Quartus Programmer to download:

c:/altera/kits/nios2/components/AlexBoard/system/AlexBoard.sof

Unrecognized EPCS device ID: 20

Jan 5, 2005 2:40:28 PM - (SEVERE) nios2-flash-programmer: Error opening target hardware

Jan 5, 2005 2:40:28 PM - (SEVERE) nios2-flash-programmer: Unable to open flash-device after successfully communicating with target.

WHERE I CAN FIND SOURCES of firmware_ROM.hex to correct that by my self ?

what i have to do????

Hello AlexS,

I'm also designing a custom board with a EPCS16 device, and I have thought about your problem. I think you are right, EPCS16 is not supported with nios 1.01 software. I think it's yet available a new version of the nios software, 1.1, but I don't know if this serious problem is there resolved.

I'm thinking about the posibility of programming the flash memory with a programm made by myself through the debbuger, by using the HAL functions for the "EPCS Device Controller Core with Avalon Interface". That may work out, but there is a problem more: Some of this functions read the ID for the EPCS device, and they don't consider the ID for the EPCS16 (I think is 20h). Perhaps you can change a little these functions and get the problem resolved.
