[Xen-devel] Flashing SLOF on IBM JS20 (Thamesblue supercomputer)

[Ahmad Hassan <ahmad.hassan@xxxxxxxxx>]

Hi,

We are trying to set up XEN testbed on Thamesblue Supercomputer which has IBM JS20 Blades. I compiled the SLOF firmware from the source on one of the blade. The compilation went smooth and generated the following binaries

boot_rom.bin
boot_rom_bimini.bin

When we try to flash boot_rom.bin firmware binary then we get the following error:

update_flash: RTAS: validate() Invalid candidate image for this platform

whereas if we try to flash the original IBM firmware then it install smoothly as shown below:

update_flash -f /etc/microcode/ibm_fw_bios_

fw08401160_anyos_ppc64.img
info: Temporary side will be updated with a newer or
identical image

Projected Flash Update Results:
Current T Image: 2b606_470
Current P Image: 2b405_131
New T Image:     2b608_401
New P Image:     2b405_131
Flash image ready...rebooting the system ...


I used the following procedure to compile the slof-JX-1.4.0-0 on IBM JS20 blade

$ tar xzf slof-JX-1.4.0-0.tar.gz
$ tar xzf slof-JX-1.4.0-0-oco-gcc412.tar.gz
$ cd  slof-JX-1.4.0-0-oco-gcc412

$ chmod 777 install-oco.sh
$ $ ./install-oco.sh ../slof-JX-1.4.0-0

$ cd ../slof-JX-1.4.0-0
$ export CROSS="" # native compiler

c06b11:/home/ah/firmware/slof-JX-1.4.0-0 # make -s
******** Building js2x system ********
 ====== Building slof ======
 ====== Building rtas ======
 ====== Building clients ======
 ====== Building boot_rom_js2x.bin ======
 ====== Building boot_rom_bimini.bin ======

Please help.

Thanks.

Best Regards, Hassan
