Hello,
recently I tried to upgrade my zxuno with the file FLASH.ZX1 from the official download page. I believe it is version 4.1.
After a "successful" flash, the zxuno booted the last selected default core, but the boot menu & setup didn't work (after pressing esc or f2 made my zxuno frozen).
Since I have xilinx platform cable I thought I could debrick my zxuno.
I tried so. I used recovery.73.bit found somewhere on the net.
After unsuccessful attempts with the above FLASH.ZX1 ( it gave bad partition or file size).
I used other recovery.bit and managed to flash the abovementioned file. After that the zxuno booted with a colorful screen saying that I should not be able to see that screen!
I found another FLASH.ZX1 file with size 16MB. I flashed it with recovery.73.bit succesfuly this time.
After that my zxuno displays black screen (both with composite & VGA outputs).
I'm still able to load recovery bitstream file so the board is semiworking.
How can I fix my zxuno? Is there any .mcs file I could use?
Please explain me what are exactly FLASH.ZX1, FIRMWARE.ZX1, etc - I'm not sure what is what. I don't understand zxuno boot architecture.
I'll be glad if you point me to some docs describing this.
Where do I find working firmwares & recovery files?
What is current zxuno repository I found a subversion and another git one?
At the end I have to say that I think zxuno is great piece of tech! I want to thank all people involved in its design & development.
Thank you!

Re: bad flash problem
Hello,
First you should test the hardware to check if everything is OK.
For this you can use the following bit file:
If your board has 512KB of RAM: http://svn.zxuno.com/svn/zxuno/cores/co ... rod_v4.bit
If your board has 2MB of RAM: http://svn.zxuno.com/svn/zxuno/cores/co ... rod_v4.bit
If the hardware is OK use the following recovery bit file:
https://github.com/ManuFerHi/ZXUNO_VGA_ ... ery.73.bit
Then copy the following file to a SD Card an place it on the ZX-UNO:
https://github.com/ManuFerHi/ZXUNO_VGA_ ... /FLASH.ZX1
Now you can flash your ZX-UNO with the file that is on the SD card. At the end your UNO should work fine.
