No Propeller 1 found on any serial port
Just started happening recently.
First time access a P1 is okay.
Can detect hardware or load ram just fine.
Once.
But second time - No propeller found.
Unplug and reconnect -
It's Baa-ack...
What's that about?

Is there a program running on your P1 that is interfering with the download process. If you have a reset button on your P1 board, press it and release just before as you click to download.
Yes, there is a program running from ROM.
But pressing the reset button just before clicking on the menu item
didn't do anything different. (Quickstart)
Still have to cycle the USB cable
Checking preferences -
Propeller reset signal is supposed o be DTR & RTS?
It is working correctly that way at least.
Standard Propeller Plug and board designs use DTR as the reset signal for the Propeller. I found the QuickStart schematic on my computer and verified this.
Thanks, Jon.
When I checked it (finally) Prop Tool was set DTR only.
Set for DTR/RTS made Prop Tool work.
I just now changed the USB cable and Reset back to DTR.
All good.
Bad Cable?
