Hi,
I am new to Arduino Yun. I tried to install nodejs, johhny-five based on the instruction from http://linino.org/doku.php?id=wiki:nodejs#test_firmata. Somehow the installation stuck at the installing the Johnny-Five part and took forever to complete. When I reboot the Yun the linino Linux had problem to boot. Hold wifi rest for 60 seconds does not solve the booting problem. While I tried to load the sketch YunSerialTerminal from the Arduino IDE to access the serial port of 32u4 but it never worked. The uploading process could not complete because of the port is busy. I tried two Yun boards and got the same problem. I suspect the standardfirmata I uploaded when installing the Jonny-Five may prevent YunSeiralTerminal from loading. Do you guys have any suggestions about how to bring Yun back to live? Thanks.
