Hi Scott:
I am still stuck at Linux kernel booting in MPC8343EA based board.
I have disabled "Ethernet, PCI, USB, dma engines " in the *.dts file and
also in the kernel config.
I am using MPC8349emitxgp.dts ; enabled MPC8349ITX support in kernel config
also. In fact, I tried building MPC8349emITX; MPC8349MDS also. Same
behaviour!
With this, the kernel boots up (explicitly passing the DTB file and cuImage
NEVER worked) and hangs after
I am using Linux-V-2.6.27.18 and using powerpc-e300c3-gnu toolchain -
gcc-4.1.69-eglibc-2.5.69-1 to build u-boot-1.3.2 & linux.
With this, the kernel boots up (explicitly passing the DTB file and cuImage
NEVER worked) and hangs after printing
"Calibrating delay loop... 133.12 BogoMIPS (lpj=266240)"
With a few debug printks looks like the kernel hangs in
"cpu_idle" in --main/init.c
Any clues..?? HELP!!!
Please find the dts file and screen-dump below:
Thanks,
Junita
