Updating Firmware
Firmware Upgrade Quick-Start
Your Talos II system contains three primary firmware components -- the system control FPGA, the BMC, and the host PNOR. The BMC and host PNOR are easily upgradeable over a network connection In contrast, the FPGA is rarely changed. Should an FPGA upgrade be desired, a direct SPI programming connection to a Flashrom compatible system is required via J10107.
BMC
NOTE: The BMC should never need to be fully reprogrammed. Erasing the entire BMC Flash device will also erase U-Boot and its associated environment variables, requiring that they be reloaded from information printed on the mainboard itself. In particular, from the factory, the IPMI MAC address is stored in both the U-Boot loader via the default environment variable string, and the currently active U-Boot environment variables. This IPMI MAC address may also be found on the mainboard below CPU0 should you need to reprogram it for any reason.
The preferred method of BMC update is to take the BMC update files that you have either compiled or obtained from official Raptor Computing Systems sources, and to upload them to the BMC. Once uploaded, the BMC is able to self-update.
Upgrade by transferring the following two files to /run/initramfs/ on the BMC:
- image-kernel
- image-rofs
After transfer, reboot the BMC via the 'reboot' command over SSH or the local BMC serial console.
Default BMC login information is contained in the User's Guide. scp or any similar utility is capable of transferring the upgrade files.
Host PNOR
The host PNOR device, which contains hostboot, skiboot, and other host-level firmware components required to IPL your Talos II system, is able to be modified in its entirety via the BMC.
With chassis power off, but standby power on, transfer the upgrade .pnor file to the BMC's /tmp/ directory. Once the transfer is complete, log in to the BMC via SSH.
Execute the following command: pflash -E -p /tmp/<your PNOR file>
If no errors occur, the upgrade is complete. You may now power on and use your updated system.
