I have following problem:
I have followed all instructions (https://static.dev.sifive.com/dev-kits/hifive1/hifive1-getting-started-v1.0.2.pdf) (15. page). I have tried several usb ports, I reinstalled Arduino IDE. I tried all settings. I tried all serial ports. I even connected Arduino uno and it worked instantly (after changing back correct compiler and other things)
I am using latest Arduino IDE on Ubuntu 19.04 and I have HiFive1 Rev B. (RGB led demo program is working)
Does anybody know how to solve problem? Do I have defective unit? Please help
Edit: I red documentation for older board. HiFive1 Rev B doesn’t support Arduino IDE. Only options are Freedom Studio and command line tool.
