I opened the PW4 and now I get access to the serial port.
I thought to use the same way as PW3 serial JB but when I hit a key to stop autoboot, this is not the uboot prompt but I have the message
"Enter fastboot mode, use Ctrl+C to exit."

I tried to use a fastboot utility but it can't find any device.

Ctrl+C does nothing expect repeat the message
I have to reboot with a 15 seconds press on power button

Does anyone have a clue to get further and acces a serial console ?
