Hi,
I don't think that your card has a problem, I think it isn't configured properly. The LynxEM4+ Rev. BA has an 32 bits internal memory bus, the Rev. AA has a 64 bits internal memory bus. For the Rev BA, you need to switch ON the SW2:7 configuration switch.
I hope this helps. Best regards

Hello,
Highly possible this is not related to U-Boot but I would like to know if someone has ran into the same problem.
We bought a SM712+ card::LynxEM4+ Rev.BA Eval Board -> DK712GX04PC00 PCI Evaboard... But this card seems problematic. I enabled it in U-Boot and was able to boot normally. There is no error. But display is something strange. The problem is that some pixels are painted, some successor pixels are black, some successor pixels are painted, some successor pixels are black, ... etc. This space seems equal. I tried some resolutions to see what is the problem. It is such that at 640*480*8 res.: 4 pix painted + 4 pix black + 4 pix painted + 4 pix black etc. This problem is in horizantal line. There is no problem in vertical line except same columns are black! I tried to illuminate the black pixels to see what happens and although I could achieve to change painted pixels from U-Boot cmdline, I couldnt manage to change black pixels as expected.
In fact, as we bought the card, I wanted to sure if this card was working or not. So I tried it in Windows. Because It had already got the drivers.(This test doesnt ensure the card working properly under Linux but I think still it was important in hardware point of view) It worked only in WinXP and Vestel monitor combo. It wasnt succesful in some combinations of Winxx and monitor combo.
I think this card is not working properly in the means of hardware point of view. Does anyone come across the same or similar problems?
