My Question is with GERMS and NIOS II does the command (detailed below) still support writing to flash memory? M0700000:AAAA AAAA (This is a example write to memory including flash that was used in previous versions of NIOS) Thanks for your help!!

Yeah,I got a similar question with you: Can GERMS monitor be used in NiosII?And,how?

Yes, Germs can be implemented in NIOSII it requires the following, 1) Add "Legacy On Chip Memory" component. (a) Select ROM in the Attributes Tab (http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif Select GERMS in the Content Tab © Press finish and then name your component 2) Make sure you have a Uart that you can talk to GERMS with, I use a RS232 port at 115200 baud 3) Goto More CPU settings and select Legacy SDK support. You must select this or the GERMs monitor will not get compiled at compile time. 4) Change the "Reset Address" "Memory Module" to the name of the Legacy on chip memory that you made above. 5) Under "Host Communications" in the Legacy section change it to the Uart you want GERMS to communicate on. After you have done the above compile your NIOS and then compile your Quartus project and GERMS should bootup for you. My original question pertains to CFI for flash, and was it ported to GERMS in NIOSII? Good LUCK!!

Sorry Somehow I screwed up the formating above!!!!

Thanks to btaylor! But when I added the Legacy On-chip Memory into my design, I found SOPCBuilder gave warning message about its not recommending of use Legacy SDk. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif So I wonder whether there is an alternative way to implement the function of GERMS but without using Legacy SDK?

freezy2000 I also got the same warning when I compiled my NIOS Core, I still went ahead a finished compiling the entire project and the tried talking to the GERMs mointor through nios2-run.exe terminal and was able to send GERMS some commands. I was able to write data to SRAM and it worked fine, I had trouble writting to FLASH however, it may be a problem on my circuit board that I have not yet discovered or maybe GERMS does not support CFI. Not sure at this point. There maybe away to use GERMs without Legacy SDK if you can find the GERMS.hex file and then use the ON Chip memory component in the MEMORY folder. Then change the reset location to that location. Maybe it would work. Good Luck with your efforts in using GERMS.

If you just want GERMS see this link - http://forum.niosforum.com/forum/index.php...c=3754&hl=germs (http://forum.niosforum.com/forum/index.php?showtopic=3754&hl=germs)

In Quartus 6 you can reactivate the legacy sdk by editing your system .ptf file - look for the legacy_sdk items, but it is no longer supported and therefore could be removed/broken in a future release.
