Go to SolutionAMD Platform Security Processor (PSP) Stopping R7525 From Booting
I have a Poweredge R7525 that I suspect has a bad RAM stick (server crashes and reboots while rebooting from exiting the Lifecycle Controller or UEFI and complains about slot B3, a machine check exception on CPU 2 and a whack ton of "OEM diagnostic event occurred"), so I tried swapping the dimm with another one to see if it was indeed the dimm. However, after doing that, the server wouldn't boot. It just hangs on the "please wait while the system is initializing" screen and then after about 10 minutes, I get error PST0258 stating "The AMD Platform Security Processor (PSP) detected a security-related issue while booting the server and paused the server from further booting" in the system event log.
I got around it before by having to take both CPUs out of the server and then putting CPU 2 into socket 1 and booting with just the one. After it successfully came back, I put the missing CPU into socket 2 and decided to run MemTest. However, the server crashed in the middle of it and now I'm back at square one. Is there a way to clear this that doesn't involve having to take the server apart? Powering off the server, restarting it, or unplugging and plugging back in the power cables does not help.

I am also having this problem on a Dell R7525 - the error is:
"The AMD Platform Security Processor (PSP) detected an issue during platform initialization"
But nothing else useful here. I tried updating iDRAC to latest firmware and doing a factory reset - still wont post.
I cant upgrade the bios since it never posts
Server is not under warranty any more so cant get support . Yuck

Hello,
your issue seems hard to troubleshoot.
I can suggest to put everything in a minimum to post configuration and check which is the failed part.
If you cannot determine it, problem can come from the motherboard (RAM slot).
I suggest to directly contact our supporto to make troubleshooting and see if we need to replace motherboard too.
Thanks

Did I answer your query? Please click on ‘Mark as Accepted Answer’. ‘Thumbs up’ the posts you like!This is a used server, so support was refusing to help, even though it's still under warranty! I was able to resolve the issue by doing as I had mentioned before, swapping the CPUs and booting with only one. Then I was able to put the second one back in. Please get someone at Dell to document this as there is no mention anywhere about the PSP halting boot, or error code PST0258, or resolving it without doing a CPU swap.

Hello Mattrophy,
I would like to recommend performing a power drain and then testing the system using the minimum‑to‑POST configuration. Please test with only the following components installed:
