IME, if you use ctl_set_isr, ctl_unmask_isr etc then, as others have said, you
should not get bogged down in these stroppy interrupts.
I have had no problem with the interrupts on my Crossworks/LPC2129 system. To my
great relief, the interrupt handlers for UARTs, CAN, timers, capture/match all
worked just about straightaway. Sure, there were crashes afterwards due to my
bugs, but the actual entry/exit from the handlers just worked. Even my FIQ
interrupt for the SPI/SD card worked, (OK, with help from the experienced
engineers in this group:). I do not use the A/D at the moment.
I do use the ctl OS, but from others' posts, the above 'ctl'
calls work fine without the ctl kernel, (not really surprising, since they just
set up the interrupts).
If you are not too old, you *should* be able to get the interrupts going
reliably before you snuff it
Be sure to make a will and leave all your bugs to the taxman.
Rgds,

SUCCESS!
I took the Crossfire2138 UART example and got both UARTs running.
I added the Crossfire2138 timer example (sets up both timers) and then added the RTC. No muss, no fuss.
It works just like you said. All this AND I haven't even reached retirement age yet! 8-)

As Martin said, "if you use ctl_set_isr, ctl_unmask_isr etc"...
I took the bare bones examples from Rowley and put them all together and the Rowley magic in "ctl_*()" works as advertised.
Now, why didn't *MY* version with VIC calls and "__attrribute..." work?
I dunno. THAT was my original question. *I* thought what I had should have worked. It didn't, so I came crying to this wonderful, helpful group for help. And after many vain attempts, I threw it all out and started over.
I got the 2 uarts working, added the two timers and added RTC and then added my Serial Motor driver. It works!
Maybe some day when I feel real morbid I may try to get the "manual" version of setting up the VIC, etc working. Which would be nice it I wanted to abandon Rowley libraries and go GCC all the way.
But that would lead me to Eclipse and I have "issues" with the current version that I downloaded. (I can set up a new project but I cannot find how to modify it nor add to it. But I'll look through the archives before I ask THAT question.)

An understanding of what happens when an interrupt is serviced will certainly
help -- as will peeking into the startup file.
