Altera JTAG UART used by kernel does not match IRQ assignment made in Qsys

Hi Brad,

See my comments below.

I will be interested in hearing about the output from your "cat /proc/interrupts" command.

With working design, we are getting same IRQ numbers assigned to peripherals when we run "cat /proc/interrupts" command. See following :

root:/> cat /proc/interrupts

CPU0

1: 41566 NIOS2-INTC timer

2: 86 NIOS2-INTC sls-hcd:usb1

4: 70 NIOS2-INTC altera_jtaguart

With non-working design, we are unable to run this command. Because after getting JTAG IRQ mismatch message, our control over console is lost. We are not able to write any command via Key-board.

Based on your previous comments, I assume you are using v3.10 of the linux kernel. Is that right? If not, what version are you using?

Yes, we are using v3.10 of Linux kernel.

Thanks,
