[En-Nut-Discussion] Basic loading of nut/OS applications via TFTP

[Nikolas Becker]

Hello Uwe,

thanks for the quick reply! I don't really know what you mean by UART monitor. I use the UART console, that's how I command U-Boot. The output posted in my previous mail is from this UART console. I tried three examples, even the simple ones.  But I don't get that far that this would make a difference, basically nothing happens after running tftpbootnut. I'll add a dump of the console log at the end of this mail. I'm sure my error is dead simple, I just can't find any guide on how to run Nut/OS applications besides the one I'm using, and I don't get it from there. 
My setup:
Hardware:
Ethernut 5, preprogrammed by egnite
Lan connection to our internal LAN
Console connection via null modem cable to RS232-to-USB-Bridge
Mini-USB connected to PC for Power-Supply
 
Samboot 1.4
U-Boot 2011.12
Latest stable Nut/OS version 5.1.0-1
Compiling with GNU Tools Arm Embedded 7 2018-q2
TFTP via TFTPD64 v4.62

Best regards,
    Nikolas
