i have connected two nios processors to one uart.
also i have attached one mutex in sopc builder.
but when i run(mutually exclusive) in each processor
it is saying can't open the uart permission denied. --- Quote End ---
Usually, connecting two processors to the same peripheral is a bad thing, since they can get into a fight. However, it is theoretically possible, if you use a mutex, and write your own device driver.
If you're using the HAL drivers, I'm pretty sure it won't work; you'll have to give each CPU its own UART.
