Great news, Mike. Will you put the core for DL at your web site ?
PS! Any new FW updates aswell or can I use the one I have ?

Maybe the core release has been delayed again?

Espskog,
You will need new ARM firmware as well, both will be available from the website when available. Yes, a few issues still, we will see where we are tomorrow.

Hello guys, is this good enough for the daughterboard ( XC68060RC50 rev1 with FPU and MMU working @66MHz ), or should i look for rev 6 ?

As long as the OS software can deal with the bugs in the earlier chips, anything should work fine. It will not run as fast, and will run hotter, but enough power is available and the clocking is flexible.

If you provide the latest rev 6, i would choose to buy from you... have you manage to find anything like that, or should us, future fpga replay/daughterboard buyers, keep looking for that 68060 version? thanks for the reply.

Still working on it. Getting new MC early rev devices (non-XC) is no problem, just not the bug-free latest mask set :(

Are you able to give us an idea of the cost of a '2nd best' 060? I see a few go on ebay from time to time for £50-60 (excluding the insanely priced ones) but not sure how this compares to the oriental prices.

@MikeJ: The core update beta was announced for release two weeks ago. Is there another delay? Could you briefly explain the problems? (if you have the time)

A quick status update of the production run would be nice too! :)

I havent read through the entire thread, but when are these available for sale? I would love to get back into something like this if the price isn't all crazy.

I'm (and many others) also happy to hear some news, or status report or planned roadmap ;) (including 060 daughterboard, and new core).

Indeed, an update is due. No problems, just things are taking longer than I predicted - as usual.

The SMD production is complete, they are hand soldering the connectors etc. Waiting for boxes to be printed, but the boards should leave the factory by mid-week.

I'm taking advantage of the time to sort out some other aspects of the code.
Merging in some updates from other branches, testing the cache/prefetch logic with the new DRAM controller etc.

The codebase is a major change from the minimig project, large chunks are completely new and specific to the Replay board - as is the ARM controller firmware.

There are two reasons for this. One is to optimize and clean up the code for other cores - as much as possible should be common between the Amiga and Atari implementations for example. The other is to tidy up timing issues and get the compile time and area down. There are a lot of Xilinx optimizations, which will probably upset people as they can't just use the code on other boards - but my aim is to get the cleanest, fastest solution for my board.

Finally, building for production test, for example not just memory tests but eye scan so I can be sure the memory is working with good margin for voltage / temperature etc.

Finally, as I have completely re-written all the FD/HD/OSD code and protocol there is a bit of debug to be done there as well.

Great news Mike ;)

Thanks a lot for your update status ;)

I hope receiving this new firmware soon for testing and making videos ;)

See you later ;)

I would just like to register my interest in this product: please put me on the list for one!

Thanks...:angel:

Do you use DCM to adjust the DRAM clock signal?
