Fluke 289 not quite sorted.

<< < (15/49) > >>

AnJu:
Frenky, I successfully downgraded to 1.1 version but the console works the same way.  |O
What terminal program did you use to access redboot?

frenky:
ExtraPuTTY. http://www.extraputty.com/
So I could upload binary file with xmodem.

AnJu:
Ok I will try connect with ExtraPuTTY.
Also please provide your working script too.

frenky:
I do not have a script.
My fluke is faulty so on boot-up sequence it tries to load OS from ROM/Flash, but it can't find it. (Corrupted memory?)
So it stays in redboot.
But I have read, that if you send Ctrl+C early during boot it will stop booting OS and show redboot console.
