Hi,
I am looking for bios upgrade from BMC. I looked at phosphor-ipmi-flash but
couldn’t figure out how to use this for bios upgrade. I checked few old mails
where oskar was asking about using user space application instead of kernel.
Can anyone please give steps to use any existing kernel driver or user space
Application for upgrading host firmware.
Regards
-Vijay

Hi Vijay,
You could build a host daemon and a ipmi library on BMC from phosphor-ipmi-flash
Here is the link I implement BIOS upgrade on my system
https://github.com/Nuvoton-Israel/openbmc/tree/runbmc/meta-phosphor/nuvoton-layer/recipes-phosphor/ipmi.
You need to prepare a BIOS image and a signature file for this BIOS
After you execute the command on host, ipmid in BMC will launch a script to upgrade BIOS.
For example,
sudo ./burn_my_bmc --command update --interface ipmipci --image BIOS.img --sig BIOS.img.sig --type static

Hi
How did you configure the BIOS flash device? I assume via the device tree?
I haven't tested this in a while, but I seem to remember that if the BIOS
SPI flash is not accessible Linux doesn't "detect" the device and doesn't
create the MTD, i.e. it's not accessible from the BMC. This can be the case
if the mux between BMC, PCH and BIOS SPI flash) is configured to connect
the SPI flash to the BMC at the time the BMC boots. Or is there a way to
make BMC's Linux "rescan" for SPI flash chips at runtime?
Thanks
Oskar.

Hi,
We have a gpio which could control the MUX
When I want to do BIOS upgrade, I will shut down the host and operate the gpio, and rescan, then BIOS flash will be accessible from BMC now.

Hi
How do you do the rescan? That was the part I was curious about :-D
Is it this (
https://github.com/Nuvoton-Israel/openbmc/blob/runbmc/meta-phosphor/nuvoton-layer/recipes-phosphor/ipmi/phosphor-ipmi-flash/bios-update.sh#L38
)?
cd /sys/bus/platform/devices/c0000000.fiu/driver
echo -n "c0000000.fiu" > unbind
echo -n "c0000000.fiu" > bind
If so, what's the magic "c0000000.fiu"?
Thanks

Cool, thanks!
Do you have the device tree snippet (or a reference to the DTS) handy by
any chance?
