In my quest for faster code uploads to AVR4809, today I explored using an Arduino Uno and JTAG2UPDI to create an UPDI programmer. It seemed to work quite well in the Arduino IDE. So I thought I’d give it a try in Platformio, but then whilst exploring the use of JTAG2UPDI in PIO, I found this.
I followed the link to an issue posted on github, but it’s unclear if the issue is resolved.
Anyone know if I can successfully configure pio to use JTAG2UPDI ?
Thanks for replies, is using the ftdi solution easier than what Max is suggesting? I use FTDIs with my 4809s to do the serial comms.
Might you have any further info on what needs to be done ?
thanks, but on reflection, I think what you’ve described is what I was doing via FTDI and a set up as diagrammatically described in Pyupdi here which became deprecated. I then progressed to Pymcuprog, but find that slow.
