Dear all,
as of today I have a Red Board Qwiic https://www.sparkfun.com/products/15123 and plugged it up to my laptop using a USB cable that seemed to install nicely. When I Upload in Arduino 1.8.9 it uploads the files correcly and also does as intended (e.g. blinks LED when loading the BLINK example). But then, no matter which program I upload or from which USB Port, reading on-chip flash data fails:
avrdude: reading on-chip flash data:
Reading | avrdude: stk500_recv(): programmer is not responding
############avrdude: stk500_recv(): programmer is not responding
avr_read(): error reading address 0x0000
Full log below, thanks in advance
