non-Wifi Dock version

[Caiuse]

Following on from this post viewtopic.php?f=9&t=30

I have the Dock version of Vocore and I've also managed to break the WIFI AP in the exact same way as the original post. I found the USB to TTL guide suggested in the original thread, however the dock version has those holes used by the connectors for the Dock.

Would I have to unsolder the connector to connect the USB to TTL adapter in order to regain access or is there a way to access Vocore through the USB provided by Dock?

Apologies for using the wrong words, I'm new to all of this

Thanks, Caius.

Hi, the hole for the UARTLite is not used by dock.
http://vocore.io/wiki/index/id:7, It is GPIO 15 and GPIO 16.
http://vocore.io/wiki/index/id:14, this wiki shows you how to connect to it.

Also, the dock is not soldered to VoCore, it's on a socket, you can remove it ( just be careful about the heat paste on the ethernet port )

Thanks for he advice, I realised they were sockets so I attempted to lift the dock from vocore, I ended up snapping the Ethernet casing because the thermal paste is more like super glue. Will report back once I've managed to wire the USB to TTL.

Okay, I've had a go at attaching the USB-TTL to the VoCore. I didn't want to solder so I used jumper cables and a breadboard. I've left the dock attached and I've attached both :

VoCore.RXD2 => USB_TTL.TXD
VoCore.TXD2 => USB_TTL.RXD

And the USB-TTL seems to get powered by the USB port. However I connect to the serial using Kermit with no issues but the vocore doesn't seems to show the boot message It's reported to show :

Code: Select all

U-Boot for VoCore(based on RT5350)..

Press 'x' to console...


Any ideas on what I've doing wrong / missing?

Thanks, Caius.

The USB2TTL's GND must connect with VoCore's GND. Or the data transfer will broken.
