Hi Scott,
It apparently was indeed a problem with the flash, although I don't
know how we did it because as far as I know we didn't write the flash
on that board. We had been experimenting with updating the flash on
*another* board (strictly in circuit) about that time, though, so
someone may have become confused... :-)
After scrambling a bit to locate a prom burner with a TSOP head
we're now back in business. And, heh, emboldened to write all over
them flash chips.
Thanks for the encouragement to consider it a possible software
problem! (and also for your previous notes on handling the flash
chips).

My IXP appears not to boot the BootMgr: when I turn it on, it just sets the LEDs to 00 and then sits--no output on the serial or anything. I can boot it into diagnostics but it fails (or rather, doesnt get past) the IRQ/FIQ test: it never prints test complete. All the jumpers are set to factory default. Does anyone know what is wrong with it and to how fix it?
Is this in the provided passive backplane or a PC motherboard? Have you been removing/installing the flash chips in the sockets? Are you changing the clock speed settings? I had similar trouble when installing an IXP1200 board in an active backplane with updated flash which explicitly set the clock speed. I was using a Rev B0 chip (which should run at 199 MHz) on a board which was only designed for 167 MHz. When I inadvertantly attempted to set the clock to 199 MHz very early in the boot sequence, I observed the behaviour you describe. Once I changed things so that I was only running at 167 MHz, everything was fine. Scott
