OK.. so memtest reports no error. So I blame the bug in the fpga
(known issue on this board). I have ordered a new one, now! I hope it
will bring me luck and happy QLing. :)

With js rom I get a white screen.

Osd menus works in both cases.

I might have a bug in the fpga,  but not sure if it is that .

The "official" core works just fine.

Looks like a problem with RAM data bus line DQ13 (pin 13 on
connector). RAM board DIY or bought? SDRAMv1 or v2?

What maximum frequency does the RAM test core detect?


150

The oldest core you have on your website works. Reading the change log it
looks like "adding support for v2" is the problem.

I think bought,  but I got the main board for free together with the ram
module. It is v1.

Where can I see the frequency?

I ordered a new sdram yesterday.

I think bought,  but I got the main board for free together with the ram
module. It is v1.

Where can I see the frequency?

I ordered a new sdram yesterday.
