WCC not working on OSX Sierra

[brainstorm]

This is a followup on issue https://github.com/whitecatboard/Lua-RTOS-ESP32/issues/83#issuecomment-354528807. I just wanted to make sure that after a clean reboot and go build-ing the newest whitecat-console release I still have this problem:

brainstorm:whitecat-console romanvg$ ./wcc -p /dev/cu.usbserial-FTYKHBJT -f -ffs -d

2017/12/30 17:08:53 detaching board ...
Can't connect to any board at port /dev/cu.usbserial-FTYKHBJT.

Available serial ports on your computer:

/dev/cu.Bluetooth-Incoming-Port
/dev/cu.lpss-serial2

Adding a few more debugging hints in connection.go:

brainstorm:whitecat-console romanvg$ git diff
diff --git a/connection.go b/connection.go
index 4458912..a08e563 100755
--- a/connection.go
+++ b/connection.go

+       fmt.Printf("INFO port status: %+v\n", info)
+       fmt.Printf("ERR  port status: %+v\n", err)

Yields the following:

No idea why it is opened:false but still err reports nil :/

@jolivepetrus Jaume, em pots donar un cop de mà amb tot això? ;)

After updating the libserialport from sigrok into go-serial over here:

https://github.com/brainstorm/whitecat-console/commit/e21e357b5d72abbdfc419984c97fd9dda3ab904e

I've managed to get up to the point where the data shows up in the opened serial port and the notify reports some activity but the board ends up detaching anyway:

Am I supposed to add some type of handler for boardPowerOnReset so that it can continue flashing Lua-RTOS?

Fins aviat, bon nadal i cap d'any!
