I am trying to use emonupload to change the AVR software for direct serial output. My setup is a RPi 3, Nov16 release of emonpi SW, EmonTXv3.4.1 (dated March 2015) with RF69 module. [image] Update firmware using emonUpload tool Hardware I have been working on a python ba…

Thanks Glyn, I used my CP2102 based USB-Serial converter to connect between the Rpi usb port and the EmonTX ISP port, but the emonupload program seems to get stuck on that first bootloader command. The only keystroke that has any effect is CTRL which drops out of the whole python program. I finall…

[image] shallowal: connect between the Rpi usb port and the EmonTX ISP port, The connection should be between the RasPi USB port and the emonTx UART connector not ISP. The application code is uploaded via serial UART not ISP.

Oops, I’ve confused the names of the ports. I was actually using the UART connector on the emonTx not the ISP port, I just called it the wrong name. Emonhub just reports the ‘thread is dead’ message continually, though when I tap into the output of the UART port I can see that the message is correc…

Ah to run emon upload you will have to stop emonhub since emonhub will be using the serial port
