Add build date to image

[www]

hi ,


thank you for your help. I didn't test this, but I want ask a question, if this package hasn't been updated, the time will be updated automatically or not?


Thanks,
Byron

Hi Byron,



We had a similiar need, and we use IPMI aux version for this purpose.



To get the behavior you describe, you can change your platform's phosphor-ipmi-config.bbappend



Witherspoon for example, calculates Aux rev info from VERSION_ID (git tag, I guess).

In our platforms, we instead write DDMMYYYY into IPMI Get Dev ID's aux rev info (4bytes, BCD)



"ipmitool mc info" would looks something like below:

Aux Firmware Rev Info     :

    0x22

    0x11

    0x19

    0x20



Thanks,



Raj

Dear Joseph & Vijay Khemka,



No matter what your version is, build date only represents the time when the image was created.



thanks,

Byron
