rgd serial port as std i/o

Altera_Forum · ‎03-17-2006

Hi

i would like to clarify myself

regarding the following.

in two processor system

if i attach serial port as std i/o tothe first

processor(as per alphabetical order) and the other

processor to jtag uart, if i run it is doing this

by printing on the console as

"can't open uart : permission denied"

and then it stops

what could be the reason?

also i observe that it launches in the alphabetical order.

please do comment on this.

regards

Does it works if you remove the second CPU attached to JTAG uart?

it seems more a problem of the configuration of the peripherals on the first core...

What I was saying is that the problem you have seems to me not relative to the fact you are using 2 CPUs.

Does the same problem happens when your design has just 1 CPU?
