I've inherited a Tegra2 T20-based system that I'd like to flash a new kernel to. I built this kernel using OpenEmbedded/Yocto, and the kernel sources from: - http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary When I try to flash this kernel using the same command that has always been used for this system, I get absolutely no output to the serial console when I attempt to boot. It's like the bootloader (quickboot[?]) is jumping to the wrong address and getting lost. Can anyone give me a hint as to what the problem might be, and how I can flash this new kernel? I've never used quickboot before and the docs for this system have long since been lost, so I'm kind of flying blind here... `:-} In case it's helpful, the output from flashing the 'old' kernel is appended below. (This is a 'straight', non-Android Linux build for an infotainment system, by the way...)
