Hi Mat,
This is not so weird, you probably need to find the correct entry point =
for the kernel you've built.
You can find it with the following commands (please adapt it to your =
environment):
# cd /your/current/build/sources/
# make ${MAKEFLAGS} kernel-toolchain
# make ${MAKEFLAGS} buildenv
Entering world for mipseb:mips
# nm /data/tftpboot/ar7240/boot/kernel/kernel | grep " _start"
80050100 T _start
So in this case i need to load the load the kernel at 0x80050000 and =
then start it with 'go 0x80050100'. (this kernel was built with =
KERNLOADADDR=3D0x80050000: http://pastebin.com/A1d06Eqe).
