VoCore not responding over UART
Posted: Wed Dec 24, 2014 7:39 am
Hi, so I've been able to connect over wifi just fine but wanted to try connecting with the USB2TTL. So I hooked up my VoCore to the device that came with it using the pins shown in the diagram on this page http://vocore.io/wiki/index/id:14 and in the manual. I then changed my Prolific driver to 57600 8n1. Started up PuTTy (using Win 7), set connection type to serial, changed everything to those same settings and hit 'Open'. I hit enter in the console that popped up, then nothing happened. There's no sign that it's booting up or doing anything.
I've been trying to get this to work all day, I've tried attaching USB2TTL ground to different grounds on the VoCore. I've tried different combinations of settings in PuTTy and the driver. I've tried updating the driver and have looked all over this forum for different suggestions. Nothing is getting me a response from the VoCore.
One indicator that something isn't right is that the RXD light on the USB2TTL is fully on. At some point I was able to get it connected without that light being on but it still didn't respond.
I've ruled out there being any problem with the USB2TTL, and probably the driver because I'm able to loop the RXD and TXD pins and receive any response I send out. Also I know at least most of the VoCore is still working properly because I'm still able to use wifi and SSH into it just fine.
I'm a little worried I might have somehow fried something important on accident. Any suggestions on how to get it to work or ways to test if something is broken are welcome. Thanks in advance to any who respond.
