Problem with running hello_world on Lite5200 eval board

[Brian Mu]

Hi,

I would like to get some help on running hello_world on Lite5200 eval board (icecube).

I
downloaded and compiled u-boot-2009.03 successfully on my Fedora box and
tftp/flash_updated to the eval board. Here is the boot message when the
board is up:

U-Boot 2009.03 (Apr 21 2009 - 12:25:02)

I also configure/make/installed the released branch of RTEMS 4.9 by the following steps

Configure RTEMS for icecube
    cd build
   
../rtems-4.9.2/configure --target=powerpc-rtems4.9 --enable-cxx
--enable-networking --disable-itron --enable-rtemsbsp=icecube

Compile RTEMS for icecube
    make all
    su
    make install

Compile examples
    cd ../examples-4.9.2
    export RTEMS_MAKEFILE_PATH=/opt/rtems-4.9/powerpc-rtems4.9/icecube/
    make

I did add a section in the hello_world make file to create an image file (irrelevant for now since I use 'go' directly)
    /opt/rtems-4.9/bin/powerpc-rtems4.9-objcopy -R -S -O binary ${ARCH}/hello.exe ${ARCH}/hello.bin
    cat ${ARCH}/hello.bin | gzip -9 > ${ARCH}/hello.gz
    /opt/eldk_42/usr/bin/mkimage \
    -A ppc -O rtems -T kernel -a 0x40000 -e 0x40000 -n "RTEMS" \
    -d ${ARCH}/hello.gz ${ARCH}/hello.img

After
tftp hello.bin to 0x90000, then typing 'go 90000' under u-boot, nothing
gets printout. I do have a BDI3000 with me. By stepping through the
code, it seems that the code stuck at 0x9064c of the boot_card()

   *  Set the program name in case some application cares.
   */
  if ((argc > 0) && argv && argv[0])
    rtems_progname = argv[0];
  else
    rtems_progname = "RTEMS";
   10640:       3d 20 00 03     lis     r9,3
   10644:       39 29 bc 28     addi    r9,r9,-17368
   10648:       91 2d 04 94     stw     r9,1172(r13)
   1064c:       4b ff ff 50     b       1059c <boot_card+0x64>
    if (heap_start == BSP_BOOTCARD_HEAP_USES_WORK_AREA) {
      /* Use the work area start as heap start */
      heap_start = work_area_start;

I
believe I am missing some obvious stuff since everything so far has
been straightforward. I'd appreciate if someone can point out the
mistake. Thanks in advance.
