[U-Boot] stuck after redirecting stdout to nc

Hello,

On uboot loading, I checking a specific environement (called consoleddev), to decide to rediect console to nc or staying in serial. I then see some strange behaviour: if the environment tell uboot to redirect to net console, everything works well, but only if the ethernet cable is connected. if it is not connected then I see that the kernel is not loading.

*relevant environemets: ncip 192.168.3.10 ipaddr 192.168.3.33

I would appreciate your advice,

Regards,

Ran
