Hi there, Thanks for sharing the image. I put a jumper between PIN 5 and 7 (GND and RESET) before, and during the upload, I tried several times but I still got the same error everytime.
I tried to use the same versions of the tools as the ones in the tutorial (Ubuntu 18.04, Arduino 1.8.10) but when I try to install Seeed package 1.7.2 I got an error from Arduino board manager. The same for other versions untill 1.7.8. Thus for now I try with 1.7.9. Is this package version (Seeed 1.7.2) not available anymore on seeed website for download ?
If not, what could be a combination that should work ?
I wanted to test with a combination of versions that I’m sure is working.
Thanks in advance
