[U-Boot-Users] SM712 + U-Boot

[Pierre AUBERT <p.aubert@staubli.com>]

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
