Correct me if I'm wrong, but I didn't think you could use the serial console for device control because the system would be dumping data to it.  Maybe it's configurable in the kernel somewhere?

Someone please set me straight?  Thanks.

In case it helps, my approach was to instead use a USB to serial UART.  This link is fairly close to what I needed, but for Gumstix, I think a HIGH speed UART might be better, assuming one can be found.

Hi Fritz,

Most of the Gumstix expansion boards provide serial console access. For example: https://www.gumstix.com/store/product_info.php?products_id=215

I am new to gumstix and have been asked to develop some hardware to
interface with the Earthstorm.

We are very power limited and I will be using TTL levels over a serial
ASCII connection.  I can interface a UART but would prefer to save time
and I seek and extension card for serial.  Perhaps I missed something
but I cannot find an extension card in the Gumstix products that
provides serial (I see only USB and Ethernet).

Does Gumstix not provide serial add ons? Does another vendor provide
such an add on?

Thanks
Fritz
