    Hi all,
    is there any other possibility how to boot without Kermit app?
    I’m using VoidLinux distribution and there is no Kermit, C-Kermit app. 🙁

    Oh… what a fail :-/
    I’ve just scrolled down on this page, and I see that there is Minicom app which is in VoidLinux so I’ll try it 😉



    Can someone tell me, how can I boot over U-Boot from minicom?
    1. I did copy whole image of Archlinux to SD card as mentioned here: http://wiki.espressobin.net/tiki-index.php?page=Boot+from+removable+storage+-+ArchLinux
    2. Insert SD card to SD card slot.
    3. Plugin 12V
    4. Plugin USB to my PC (VoidLinux).
    5. There is some output from starting EspressoBin but I can’t write anything there:

    I’ve tried “Echo” function from MiniCom app, but it’s not possible to insert there normal text, I can delete whole output and if I write some comands after “Marvell>” there is no response.

    Can anyone help me please?

    Have you ever tried other PC? I try putty on windows system and follow the instruction, system is able to boot up normally. I think your issue is related to PC setting.



    No, I haven’t tried another PC, I just tried it at home. I can try it on Fedora22 (work PC), but I think that it isn’t problem of the PC.



    I had some trouble with minicom. Then I remembered that screen does serial connections as well and is simpler and easier in my experience. Worked perfect for me. Just do
    sudo screen /dev/ttyUSB0 115200



    Cool man, I’ll check it.

    I’ve tried to boot from Windows manchine and it works. I’m going to switch it back to Linux 😛

    was an error and board side, not at the side of terminal emulator.



    @stappers – as you can see from my comment I wrote, that I couldn’t type there anything.
    Fortunately @cuddlepuncher helped me with screen and it works like a charm 😉



    So the actual error was “can’t type anything”.

    The change in terminal emulator to get it working,
    was most likely a change to a terminal emulator that doesn’t check CTS/RTS.
    (CTS Clear To Send, RTS Request To Send )

    In minicom it can be disabled by setting “Hardware Flow Control: No”
    at serial port settings.



    putty works with serial port, and I used it to setup the initial u-boot.
