Of course something happened: your kernel crashed. > I can not get any responce from serial console. > Did I lose something? Yes. The Linux kernel, even with the mbxboot bootstrap stuff attached, is not a standalone program. It expects a lot of initialization to be done by the firmware, and some information passed, too. I don't see why you go such a difficult route. Both PPCboot and Linux are running out of the box on the TQM8xxL. Just install and run. If you want to debug your own kernel modifications, you can still use PPCBoot to load and start the kernel - but remember that PPCBoot does not use zImage files, it uses it's own image format instead. A simple but efficient way to enter the debugger _after_ Linux has started and the MMU has been turned on is to set an instruction breakpoint for the address range 0xC0000000 ... 0xC1000000 (use the "BI" command at the telnet prompt to do so).
