Garbage at reset

[Altera_Forum]

Guys, for long time I'm experiencing an interresting behavior of NIOS, but now I said enough is enough, I have to report, perhaps some of you has some solution and tell me what I'm doing wrong. The case is simple, here is a pseudo code like something: 

 void main() {  printf("start\n");    subroutine calls, etc.   printf("done'n");   while (1) ()  }  When I hit run as NIOS HW in NOIS IDE or in ECLIPSE, first time runs fine, but if I hit couple of times the reset button, what is tied to NIOS RESETn pin, I get this output on the console:  start done e start done ne start done one start done done start done  Sometimes I get more garbage. Another problem is (what I suppose being tied to this one above) I realized that if I have bunch of IPs (eg. VIP stuffs) in my NIOS, the reset does not do full reset, or so. If there are many IPs the reset does not work. I have to hit again the "run as NIOS hw", then works.  Does anyone of you have some useful hint to these problems?

Are you sure the problem isn't just that whatever is displaying the serial port data is missing the first characters of each block?

Perhaps I don't understand you well, but I think there nothing is missing, but there are unwanted additional characters, garbage. Maybe I was not accurate enough, so I repeat the console output: 

 <I run the software> start done <I hit the reset button> e start done <I hit the reset button> ne  start  done <I hit the reset button> one  start  done ... and so on.

Are you running out of onchip memory ? If you are , try enable_alt_load_copy_rwdata, else the .rwdata not initialize may cause this.

I'm using on chip memory.

Try enable_alt_load_copy_rwdata , the setting is in BSP Editor

[Altera_Forum]

I will try this, thanks.

leen, 

I confirm enable_alt_load_copy_rwdata works in 9.1sp2. The PCIe reset would reset my nios II and it wouldn't recover without this change. Now I can reboot the PCIe root complex and the nios II firmware restarts properly.
