This might be "old news", but is does show one useful application:
I added an SD card and a serial port level shifter to a Xorro card. From the XMOS community I borrowed code fort a serial port and a filesystem for the SD card.
I set it up to capture and save all incoming text to the SD card, filename was generated by date and time. Then I hooked it up to the debug output of the X1000. Once it's "running", all debug output gets saved automatically.
You could browse and import the saved files to the Amiga or remove the card and read it from anything that can read SD cards.
Because it's independent of AmigaOS, it's capable of saving it all off even when the OS is having troubles.
Now, to make this more interesting: Both the X1000 serial port AND the serial on Xena are capable of WAY higher baud rates. The limiting part are the voltage level shifters. There's a small pin header on the X5000 that will let you pick up the serial output before that shifter, so it SHOULD be possible to run the serial speeds up as fast as the SD write routines can handle. I assume the X5000 serial port can also run faster..
Unfortunately I loaned out the Xorro board and it was never returned, so you'll have to take my word for it.
Granted it's not "rocket science", but saving debug without a second machine, and the possibility to run the debug so fast that any slowdown would be minimal.. Well, it's at least useful to programmers and beta testers!
It should build out of the box and work on X1000. It's not too much code, and it just implements a simple circular stack so should be relatively self-explanatory. Might try and write something up on the blog explaining some more about it.
svn checkout https://svn.code.sf.net/p/xena-examples/code/ xena-examples
cd xena-examples/stack
make run
Oh, and yeah, this doesn’t require any extra hardware, it should just work on the plain X1000. It won’t work on X5000 even if you got it on to that chip since the localbus interface is way different.
I tried the latest XTools from your blog on my X5000/20.
This is the output. It does not seem to work fully and the tools can only be run once:

If you'd like to continue, a few tests will be performed.
1. The first test is according to the X5000 Curys TRM.
It seemed to work for one test. But then not.
2. The second test is based on loose assumptions on how
AEons Tabor motherboard works.
The only reason you would want to run these tests is to
inform the developer on your progress.
You can abort this process now by pressing Ctrl-C and enter.

Seems I don't release the XTAG resource when doing Ctrl-C in that test. Regarding the reads and writes, I've seen similar result for another X5000 user, so it's good to see that it's the same for you. I'm in contact with some other developers so I hope to get something working for X5000 soonish.
I've created a new test-version of XTools version for X5000. It now tests a few calls with differing delays. The longest delay is 10 ticks, but it also tests with 2 and 5. If anyone could you must read the X5000 section in XTools.txt in the archive to know how to test it. Archive is here: https://jaokim.github.io/files/XTools-1.7d.lha Very beta. I'm not responsible if anything breaks your machine.

They are indeed very strange. I don't know if there's some sort of weird caching issue... or have I done something totally weird. I'll see if i can come up with something new.
