I have an older IP cam I got from goodwill, and was learning more about accessing u-boot / modifying it and things like that. The part where I'm stuck at is setting up tftp to transfer an image created in u-boot, over Ethernet to my Ubuntu laptop. This is the guide I'm using: http://marcusjenkins.com/hacking-cheap-ebay-ip-camera/
I got up until about here:
setenv ipaddr x.x.x.81
setenv gatewayip x.x.x.253
setenv serverip x.x.x.43
tftp 0x82000000 romfs.cramfs 0x370000
And now I'm completely lost in what to do. Am I supposed to setup a static IP on my laptop, then also setup the same static IP from the U-boot commands? Nothing has worked so far that I have tried.The commands on that link read as if it's missing a lot of important steps. The last part of 'tftp' command, complains about not having an IP address but, I thought that would already be setup when I did the 3 network commands in u-boot. Anyone else have this many issues with this? I can't find any guides for something like this, and just wondering if anyone knows how to set this up correctly. Thanks
