I updated an S1200V3RPL board to the latest BMC release 1.12.7499 via UEFI using the software provided by this link: Intel® Download Center [1]
After the update, I wanted to change the SDR. Because [1] did not contain an SDR update utility, I tried to re-use the UEFI utility updFRUSDR.nsh provided by this link: Intel® Download Center [2]. However, the SDR update failed with a "bmclibinitialized returned failed" error after loading "ipmi.efi". Trying to downgrade the BMC firmware back to the previous version 01.12.6784 (using updBMC.nsh from [2]) again failed with the same error.
I could downgrade the BMC firmware to version 01.12.6784 by writing BMC_i_0112r6784.bin from [2| with the fwpiaupd.efi utility from [1]. However, this had no effect on the aforementioned error, i.e. re-running updFRUSDR.nsh from [2| still failed with the same error.
How do I downgrade properly to a BMC firmware where updFRUSDR.nsh from [2] can run successfully? If this is not possible, is there another way to write the SDR with the 01.12.7499 BMC firmware applied?
Thank you,
Christian
