Re: The Saga continues.... uBITX v5 Firmware update
Some Arduino Nano boards require the old bootloader the first time.toggle quoted messageShow quoted text
Choose Processor > "ATmega328P (Old Bootloader)", and press the reset button on the Nano.
Thereafter, the new bootloader should be in the Nano, and reset should be necessary.

OK thanks... well after much head scratching I discovered you have to have the Arduino Nano connected into a usb port before it shows up as a com port in device manager. Now Xloader opens the com port and when I hit upload the led on the nano blinks a couple of times then stops and it just sits there with the led on. I have tried two different com ports from my two usb ports, one is com 4 the other com 5. Both do the same thing. How should the port be configured? They are configured as follows: Data bits 8 Parity None Stop bits 1 Flow control None In Advance settings.... Use FIFO buffers is checked (requires 16550 compatible UART) The port was originally set at 9600 baud.... I set it for 115200 Neither setting works Any ideas?

If it's working correctly, you won't see anything on the desktop or lower right status area. To see if the Arduino has been assigned a port, you'll have to hit the control panel, then Device Manager, and look at Ports (COM & LPT). (The image is from a Win 10 ultimate machine but it behaves the same as my remaining Win 7 box.) If the driver isn't loaded correctly, or there's a problem with a particular USB port, you'll get an error pop-up in the lower right of the desktop when you connect the Arduino. Sometimes, using a different USB port is enough to 'force' Windows to reload/reconfigure the driver - that will usually make it work in all USB ports. 73, Andy, KG5RKP
