Hi, We tried loading a ppcboot image of linux kernel and ramdisk referring the document and http://lists.linuxppc.org/linuxppc-embedded/200108/msg00188.html. What we did is, power up both bdi2k and target. We got ppcboot prompt on the serial console. Setup the bdi2000 using serial connection from the host (using bdisetup executable) telnet to bdi2000. bdi2000 picks up the configuration file and configures target and itself. in host, ppc_82xx-gdb <path to vmlinux> put breakpoint at start_kernel
Now ideally we should be able to give bootm <image loc> <ramdisk loc> from ppcboot. but bdi2k holds the target in debug mode. In this state we are unable to enter any command into ppcboot prompt. Same behaviour is shown in our custom board also. we use the vads8260.cfg file provided by bdi2000. I think there is some configuration that we need to change in the bdi supplied file like bdimode and breakmode. Is it so? I cannot think of any other reason.
