SDIO IRQ BeagleBuddy zippy

Hi,

I'm currently working on a project which includes working with a SDIO
modem.

For this purpose, we soldered 'zippy' expansion board (http://
elinux.org/BeagleBoard_Zippy) over BeagleBoard-XM (Rev B) and enabled
its SD/MMC card socket.

Problem is: On connecting SDIO modem on zippy board's SD/MMC
everything's working fine, except irq functions. ('SDIO Probe' is
called. But, not getting any prints for 'SDIO IRQ').

Thanks,
Ashwini

Ashwini,

i'll have to double check the TRM, but from what i remember, the way
the level shifters are implemented on the Zippy precludes the usage of
sdio irqs.

Also, there is not support for SDIO interrupts in the mainline OMAP driver.

Hi Dave,

Thanks for your last reply.

left the zippy in-between & 'level shifted' myself for other methods/
possibilities.

used 'NFS' and my modem is working fine.
