Can't interrupt U-boot loading - goflex net

First of all, thanks ,Bodhi , for your great work on providing regular update for our aging Kirkwood devices. I've been using this forum for years as a main knowledge source for tweaking my pogoplugs.
I recently acquired goflexnet with a locked ssh access and currently I am facing serious difficulties trying to flash tld u-boot over serial console.
The problem is that I can not interrupt u-boot no matter what I do. I use the latest debian rootfs on sd card plugged in device with uEnv.txt in boot directory.
I tried pretty much everything that I can think of - different usb2serial converters, switching tx – rx , different wires, tried over 3 platforms – linux, win10, winXP – same story over and over. The device boots , I see the messages, when the part comes – press any key to stop u-boot appears – I cant interrupt and get access to console to “GoFlexNet>” prompt.
The kwboot method doesn’t seem to work either.
Since I am out of ideas – any help is highly appreciated.
Thanks in advance!

vertycall,

1. With serial console connected, when you let it boot all the way, do you see the stock OS login prompt? if yes, what happen when you try to enter "root" at the login prompt? Can you login?

2. If you can login or enter something at the stock login prompt, then your stock u-boot envs probably has something wrong in it that disabled the serial consol input.

3. If you cannot login or even get the login prompt to repond to anything, then either:
- Your serial converter has problem. Check this converter on a different Kirkwood box , if you have serial console on one.
or
- Your GoFlex Net serial RX pin is faulty. This would be bad, because you would have to hope that by looking at the pin connection using a magnifier you will see something wrong.

Bottom line: if you can login into stock OS then you will be able to fix it: you can flash new u-boot from stock OS. After that, you will be able to gain full control of serial console.

Hi Bodhi and thanks for your quick response.
Unfortunately I cant see login prompt during the boot. N
I provide a full log of the u-boot screen with rootfs in sd attached.

I will try to establish uboot session to my pogoplug v 4 to check if everything is ok with the usb-ttl adapter.

Right here. You are in stock OS. Try typing something here to see if serial console input is working.

You can also do a quick loop back test to check your serial converter: disconnect the serial wire going to your GFNet, and connect your serial converter TX to RX, and type something to see if it echos back.
