I follow the manual of the development kit - basic (UM-B-025_DA14580_Bluetooth_Smart Development_Kit_Basic.pdf) until the on page 18/26.
1) the UART connection appears on my laptop (windows 8, 64 bit) as COM4 under "Ports" instead of under "USB Serial Port". I guess that won't cause the garbled character problem in the serial connection with Tera.
2) after I set up the Tera configuration, Tera terminal appears all the garbled characters.
3) On step 6.1.15, after I click Start/stop debug session, a window "Error: Flash Download failed " pop out.
Anyone can help me with this? Thanks
