How to reflash the ST-LINK
==========================
To reflash the ST-LINK, connect the device to a programmer as before while keeping pins 7 and 8 shorted. While the LED is blinking, run openocd. Once it’s running (i.e. it doesn’t show any errors), you can unshort the pins.
Then use the following to unlock and reflash.
```
reset halt
stm32f1x unlock 0
reset halt
stm32f1x mass_erase 0
flash write_bank 0 ./build/gnuk.bin 0
stm32f1x lock 0
reset halt
```
***Note: That reprograming will wipe the flash memory and you will lose all key's that was on the device.***
Testing Gnuk
============
Type following command to see if GnuPG detects the Gnuk token.
