SOLVED: Garbage output over 1024x768 with 256 colors or more

[johannes]

Hi folks,

finally a new, well NOS, CT63 made it to me and I checked out my SV sitting around here for some month. Setting up the SV was pretty straight forward and plug&play. I managed to get nice resolutions up to 1280x1024 with 16 colors. This is my LCDs native resolution. But when increasing color depth to 256 or even 65k I get garbage output on the screen (see picture).

Setup:

CT63 running fine@95Mhz (factory setting), ABE/SDR v7
512 MB Kingston SDRAM
SuperVidel v2, default SV.INF
No bus boost
No other extensions
14 MB Ramcard by Lynxman
PicoPSU 80w

What I've tried:

- CT63 Boot flash version 2.00, 2.01, 1.03c
- Different monitors
- VGA/DVI output
- Plain TOS (only SV Driver in AUTO Folder)
- NVDI 5 with SV supplied ASSIGN.SYS and drivers

This is not getting better... Any thoughts where to search or what to try else? Perhaps it is important: At boot the ATARI - Logo from CT63 screen is not shown correctly at SV output, on Videl Output everything is fine.

Additional question: How do I get ST-LOW running with the SV? When I switch to ST-LOW, I always get a "Frequency out of band" on different monitors (LCD/CRT)

Thanks for any input!

Cheers
Johannes

Hi.
Have you soldered the 3 wires from the SV to the MB for the correct videl clock?

Hi Fredrik,

Not yet. I learned from the manual that v/h Sync is only required for games/demos and not for desktop stuff.

Never seen this one before.

Weird boot logo is nothing to worry about, but what happens next looks weird in a bad way. Do you know which FPGA firmware revision you're using?

EDIT: Now that I think of it, I think I have seen this before. You should most probably update your FPGA firmware.

Hi Shoggoth,

typical beginners mistake. Receiving the SV this year, I thought it would have the newest Firmware. It was 001 After upgrading on 006, everything is fine. Awesome!!! Also, 320x200 works flawless. I am really happy.

Now I am going for MiNT and the Svethlana.

Thanks for your support!
