8- After "ctrl+C" / unplug+reconnect miniusb / open putty session on COM14 / rest the plug : should I expect to get the exact same ouput logs in Putty session screen ??
YES AND NO : through my various attemp, inserting the sd card at different stage, I always got to the same step after the plug reset :
Basically after the flash burn procedure finished, you should disconnect the mini USB and connect it again (do not remove the SD card during the installation procedure).
This action is needed since windows does not release the USB device until the USB cable is removed from the PC. I tried several openocd actions but none helped.
So if windows does not release the FTDI driver (in case you do not remove the USB cable), you will not be able to see to console since windows does not allow both ports to be active (FTDI JTAG and Console) unlike Linux that does support opening ports for both devices.
The problem is this, disconnecting the USB cable might cause a HW reset which might interfer with the installation procedure, this is why you should do the disconnect of the mini USB right after the burn finished or wait several minutes for the intallation to finish, without opening the serial, it is hard to know when it finishes, a HW reset should indicate the process end (all LEDs light up).
