What about using the the MPC564 development board just for the onboard programmer
https://www.nxp.com/design/design-cente ... K-MPC5634M
I'm currently working on a target with the spc563 processor (vitesco M4C) using the ghidra emulator and it has been enough but thinking on getting the 150 USD board I referred above.

How's $25 sound for inexpensive?
I'll get into this in more detail later if someone wants me to. Here's the high level summary. It works, but it was clunky as hell to set up. I can't seamlessly suspend and resume the CPU, but I can halt on connect, run to breakpoints, step through code, and dump
all of the flash. Code, data, and shadow. I can see the active RAM, and the registers. Those were the main things I wanted. Once I learn my way around the program a little more I'm sure I'll be able to come up with a more comprehensive workspace.
Damn, that's pretty cool. I'd like to skill up to that level one day.

How would you break out the debug pins to get them away from the 564 that's part of the board?

Thanks. I still feel like a monkey banging rocks together most days.

I was under the impression that the programmer/debugger could be used with external devices just like STs discovery boards, but looking at the manual it is obvious you are right and it cannot (easily at least).
The thing is that the cyclone is normally much more expensive than what it got it at.

The regular PE Multilink should work too. But since you're doing 5xx instead of the newer 5xxx, you're probably going to have software hassles like 04coly was talking about.

Cheap OSJTAG I bought from Aliexpress worked fine for me, both for reading/writing the flash or debugging with CodeWarrior on MPC 55/56 microcontrollers.
