Hi,
we have a different WLAN chip (WL1837) on the GTA04 so I have
a different setup (device tree, firmware) compared to A3 and A4.

But it does not work well:

Exactly the same user-space and kernel works on the Pyra with the
same WL1837.

So the key difference might be hardware related (MMC interface of OMAP3 vs. OMAP5).

Any suggestions how to debug?

Nikolaus
