Error when entering in recover mode colibri VF61 - viola 1.1

I typed this command on the terminal ./update.sh -n -d /dev/ttyUSB0 and when this message appeared Colibri VF rootfs detected Put the module in recovery mode and press [ENTER]... I turned on the module short circuiting these pins and this message appear:

Colibri VF rootfs detected

I don’t quite see what error you are talking about. What exactly is it that does not work for you? E.g. as per the following article on our developer website you should now be getting the U-Boot prompt on that same serial debug line.

OK, sorry. Now I see it (;-p). Yes, this should look as follows (this with 2.7b2):

What kind of a serial connection are you using? Did you bridge RTS/CTS as outlined in the following article? Have you tried another module? Is this the first time doing this?
