Hi,
Jepalza has ported the principe of conception Xilinx 2011 FPGAmstrad version on ZX-Uno, so then I bought on (65€ this little one), and help him realizing a first stabilised version.
https://www.youtube.com/watch?v=tpr9xxx1rsAZX-Uno has the same chip size than one I used in 2011 (100% of chip used...). So normaly I can reach the "candidate 002".
http://www.cpcwiki.eu/index.php/FPGAmstrad#VideoIt is a very light version (no dsk write access, 640x480, MEM_wr WAITn generator...), but easy to use, and having a clean simple code source (no options addons) that match fully with the FPGAmstrad wiki story.
May interest ones having a ZX-Uno

Efforts done here :
- I removed the pll that was not determinist, and I recalibrated all clocks
- merge of SPI/FAT32 part, SDHC compatible : up to 4GB files inside (can use a 32GB also but filled less than 4GB of files)
- merge of PPI
- merge of interrupts
- page-up key does reset+insert next disk, if you do a continuous pressing it does increment inserting this way a quite of "random disk", after last disk, the first one is re-inserted
- merge of PWM (high quality sound, but mono)
- my joystick is not running fine on my own ZX-Uno, normaly mapped
- keyboard merged
TODO :
- merge of CRTC0
- joystick validation
