Yes, I think the v2 has reached its maximum potential. possibly a v4 500/600 in the future with cyclone 5?

So whats the flash cycle limit on a Cyclone 3?

Could it not be possible to orchestrate a boot option for different cores? (like I suggested half joking earlier, but it seems like everyone wants something different so maybe its the only viable option)

It could just boot fast with the current core, or give the option to flash a different one (which obviously takes a bit longer to boot then).

Well, its probably possible, but it might likely cause a mess, since OS might expect or be configured for different - its better to leave it to knowledgeable user, then to make it "too easy".

Once AmigaOS EXE core flashes are out, its quite easy to "reflash", even Blasting is not that complex, once you get used to it.

Surely some sort of early autoboot config file can do this?

Ive not got my v500 working yet, so dont know how much of a PITA the reflash time would be.

FPGAs use sram inside so their config can be overwritten any times without degrading. The problem is the flash chip which stores the code while the device is turned off. That has a limted lifecycle (write cycle).
  How I would do is to store different firmwares (e.g. CPU+AGA only, CPU+RTG+FPU only) on the amiga filesystem in a dedicated directory and write/modify the amiga early setup which is reachable during power on holding the two mouse buttons pressed. So the vampire would start up with the firmware which is on the flash chip and the user could change the firmware in the early setup. The ROM code would load the firmware directly to sram of the fpga. The change would not be resident so after turning the amiga off the firmware from the flash would be loaded again.
  The difficulty is however that the fpga could not load its own program while it is being reprogrammed so probably it is not possible without HW modification...

Impossible to reach in a lifetime. :-)

  Ok, so Im not sure what sort of chaos has happened recently with the Facebook poll for what people want the Vampire 500/600 core to finally include (I dont use FB), but this, if written smoothly can be an option.
 
  Not sure how long a re-flash takes, but you could have various core builds with AGA/FPU/RTG/Whatever you like.
 
  Im starting to feel sorry for the V4SA>v2 backport guys. People are pulling in all directions, it seems. :)

@Istvan Hegedus
What a brilliant idea to have a boot menu with the two mouse buttons just like a classic Amiga! :-)

  Sorry, must have missed your post.
 
  This would be very much heading in the right direction. :)
 
  Im hoping somewhere along these lines we can find a good working solution.

Hello everybody!
Today I want to give Gold3 Alpha a try.
Is there anything special I have to pay attention for? Except from resolution-changing to 640x256 and deleting "overscan.prefs"?
Can I stay with Coffin R58, or do I have to install a different OS?

Thanks in advantage and many greetings
Oliver

P.S.: Will the disk drive really be without function?

Okay - I got it running, but it's no real joy ... perhaps I did something wrong,
I don't know. Coffin didn't start at all - only a weird yellow/blue flickering
screen. So I plugged in a CF-Card from my non vampired A500 with
OS 3.1.4 installed. After deactivating the CPU-Check in the startup-sequence
it started, but only I could only play about 10% of the AGA-Games. I
didn't try much longer and flashed back to core 2.12. I will wait until
perhaps the Core3 will be better developed for the V500 ... of course
it was nice to see the 256 colors ... let's see what comes in the future.

Good night to everyone
Oliver

P.S.: I write this of course on my Amiga ... ;-)

Coffin is made with RTG and higher resolutions in mind - Plain OS 3.x with SAGA drivers. More apps work then games. Dont forget its nice to see more ChipRAM :)

Would be interesting to see if it were possible to run it like a DRACO?

EXTERNAL LINK 
Which is amiga based but does not use the traditional chipset.
