This is impossible to say without knowing where and what the bug is. Best regards, Wolfgang Denk You're right. What I did see in my tests is as follows: 1. only if there is connection to PC and the PC's interface ip is the same as the ncip environement, then and only then, I see that the u-boot finish its job and starts the bootcmd, and loading the kernel. I also see the u-boot prints in the ethernet if I start netconsole, but event without starting netconsole, the kernel starts (as expected) 2. Otherwise, if the network interface ip is not the same as ncip, or cable is disconnected the u-boot does not start bootcmd, and I actually do not know where it stoped and why. Please tell me if you have any advice where to look, and what should be checked, Best Regards, Ran ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[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 -- View this message in context: http://old.nabble.com/stuck-after-redirecting-stdout-to-nc-tp33066296p33066296.html Sent from the Uboot - Users mailing list archive at Nabble.com. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
