Hi community member,

Would you please provide your advice for my request?

[Request]

Now, we would like to change the MMC connection from 1 to 2.

At this time, where should we change the software on linux?

In my understanding, we should change the following settings at least.

- mux.c file

- DTS file

Any other?

Best regards.

Hi Biser,

Could you please check our DTS file?

My customer could not access the WI-FI module via MMC2 even though change the pinmux at DTS file.

Note: When they used the MMC1, the application can access that module.

Also, they used the Beagleboneblack and angstrom linux.(Version 3.8)

Or where should we check?

Best regards.

Sorry, I'm not a Linux expert so I cannot check your DTS. BBB + Angstrom Linux are a community project and they are supported at http://beagleboard.org/Community/Forums
