No. the old one is ending. Journal submission is just around the
corner here in India. And NXP or some smart sales guy must be dishing
out arm devices and development kits to the college labs.

Hi,
Jeff has spotted your problem. With "VECTORED_IRQ_ INTERRUPTS" defined
your interrupt handler will be called directly by the VIC so the
interrupt("IRQ" ) attribute is required. If you remove the define
"VECTORED_IRQ_ INTERRUPTS" then all interrupts are handled by
irq_handler which calls the regular function held in the VIC register.
Regards
Michael

Just make sure it isn't defined, you shouldn't need to modify the
startup file.

Look in the examples folder of the compiler and read the documentation.
Heck, did the new semester start ???

Hi Ernst,
if you upload youre code to the files section. i'm willing to have a look
at
it. not that i'm an expert but i use rowley and also do some ISR code
using
2148 and 2468 both with CTL. so just upload if you will and give me a mail.
