The part I'm not getting is the initramfs. Is this a full image or just a boot image?
Based on the link you show, it looks like I can install a full imag eusing tftp then run that image on the device without overwriting the original. Once logged into the new image, I can extract the old image.
The loader says AR9330 while this link shows AR9331 so it's probably not this one.
Load the kernel in memory: tftpboot YourKernelName.bin
Boot the loaded kernel from memory: bootm
Does kernel mean a whole, complete firmware image or just some part, like a boot only or something.
And more importantly, how do I figure out what the proper repo build is for this device?
I know it's Chaos Calmer 15.05. I know it's Atheros AR9330.
I think it's got 32m ram and /64m storage.
What else do I need to know to find the correct repo?
