Hi, I just made my own Null Serial Cable for the gumstix. Using the correct connections etc. I am just testing it and it seems to freeze after the following is displayed: U-Boot 1.1.1 (Oct 3 2004 - 18:38:12) *** Welcome to Gumstix *** U-Boot code: A3F00000 -> A3F1B01C BSS: -> A3F4CB54 RAM Configuration: Bank #0: a0000000 64 MB erase_region_count = 32 erase_region_size = 131072 Flash: 4 MB Hit any key to stop autoboot: 0 GUM> > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > After that my computer (Win XP) just makes a "Dink" noise every half a second or so.

Looks like the gumstix is receiving some character over the cable -- maybe 0x00 or 0xff C On Mar 31, 2005, at 9:12 AM, Paul Hampson wrote: > Hi, > > I just made my own Null Serial Cable for the gumstix.

Is this due to a short circuit somewhere or a miswired connection?

Well the fact that you're seeing valid characters at all (i.e. the u-boot message) suggests that the Tx wiring (from the gumstix perspective) is just fine. Perhaps the Rx wire is screwed up (which would cause a continuous stream of breaks?) -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

I would say that your Rx wire is shorted with something that carries power.

It seems that RTS had got wired to pin 1, not 2 of the DIN and the CTS connection had got to pin 8, not 6 of the DIN plug. Oops! A simple resoldering of these should fix it! I have to say that I find the DIN drawings a slight confusing as to the orientation, hence the swapping from side to side... hehe! Thanks for your help!
