Title: Unused GPIO-Pins of SMSC9512 / iMX233-OLINUXINO-MAXI
Post by: Chris on January 21, 2015, 05:53:41 am
I saw in the User's Manual of my iMX233-OLINUXINO-MAXI that there are 6 GPIO-Pins of the SMSC9512-Chip, that are unused / not connected to anything (GPIO0, GPIO3 - GPIO7). May it be possible to access and use these GPIOs? (Of course you have to solder wires from the SMSC9512-Chip, just asking for the accessibility by any software)

Hi Chris,

The SMSC9512 is a Fast Ethernet and USB Host Controller IC.

Why do you want to use the GPIOs of this IC?

Mike
