RE: [ts-7000] using ttyS2 on ts7800

["Robert Joslyn" <>]

I don’t think the 7800 has anything at ttyS2.  ttyS0 and ttyS1 are the two serial ports built into the Marvel chip.  The rest of the serial ports are implemented on the FPGA and are named as ttts0, ttts1, etc.

 

The ports are documented in the manual http://www.embeddedarm.com/about/resource.php?item=393#section5.1

Hello all,

Could someone tell me how to use ttyS2? I tried to open it only to get the following error:

FATAL: failed to add device /dev/ttyS2: Filedes is not a tty

Rgds,
