i am using a Rak 3272S-Board with latest firmware (RAK3172-E_latest.bin) from downloadpage.
I started the first steps with Arduino 1.8.9 and RAKwireless WisBlock Core modules.
I chose the WisDuo RAK3172 Evaluation Bord and use the LoRaWAN OTTA-example.
When i want to flasch the board with a FTDI-Board and Programmer: AVRISP mkll i got the message:
Device is not in boot mode
Detect baudratefail, can not get the baudrate
With STM32Cube-Programmer i can flash the RAK3272S-board.
So how can i programm the board?
