My HiFive1 just arrived, exciting!
I plugged it into my iMac via the micro-USB plug and can see the RGB LED cycling neatly, so it’s not DOA.
However if i do ls /dev | grep serial
i cannot find any USB serial device corresponding.
I also checked in ‘about this mac’ > system report > USB and cannot see the device in the USB tree anywhere.
I have a super-cheap FTDI board that when i plug into USB it works every time.
I went to the FTDI website and downloaded and installed their macOS drivers, rebooted, but still can’t see it unfortunately.
Any tips?
Thanks all
This folder exists:
/Library/Extensions/FTDIUSBSerialDriver.kext
But if i do the following, it doesn’t appear to be loaded:
kextstat | grep FTDI
I tried:
sudo kextload /Library/Extensions/FTDIUSBSerialDriver.kext
Then kextstat shows it being loaded:
kextstat | grep FTDI
But still doesn’t work unfortunately
Fixed it! Used a different cable and works now. Maybe FTDI was browning out. Odd that the RGB LED was fine.
Oh well, onwards!

Might be fun for others to know: It comes up with 4 devices:
cu.usbserial-00006014A
cu.usbserial-00006014B
tty.usbserial-00006014A
tty.usbserial-00006014B
A didn’t do much, so i did the following (you might need to brew install picocom
first)
picocom -b 115200 /dev/cu.usbserial-00006014B
Then pressed the reset button (red), and got this fun demo!
