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

Hello Brad,

At the beginning you mentioned following :

In Qsys, I assigned the following Nios II interrupts for these system components:

timer: IRQ 0

jtaguart: IRQ 1

usbhc: IRQ 2

--- Quote End ---

Later you mentioned following,

In addition, when I forced the Altera JTAG UART interrupt to IRQ 0 to match the Qsys setting by modifying the altera_jtaguart driver, when the kernel attempts to attach IRQ 0 to the JTAG UART, the following error message was displayed:

altera_jtaguart: unable to attach Altera JTAG UART 0 interrupt vector=0

--- Quote End ---

Should not you try to force Altera JTAG UART interrupt to IRQ 1, not IRQ 0 ( to match that with Qsys setting.)?

Cheers,
