Re: [coreboot] Has anyone built the memtest86+ payload recently?

[Jay Talbott]

Hi Martin,

He was following the instructions on the coreboot website: https://www.coreboot.org/Memtest86%2B

Obviously that must be completely out of date if there’s now a version available from the coreboot site.

Let me see what he can do with that.

We just want to build it as an elf and use it as the primary payload for some validation checks on the memory – the normal/production payload is a Linux kernel.

Thanks,

- Jay

Hi Jay,
  Are they using the coreboot version of memtest86plus?
  What commit is being built?
  What version of GCC?

Building with GCC 7.3.0 from the latest commit at review.coreboot.org/memtest86plus, I do get one warning that should be cleaned up, but it builds fine.  The errors you posted look to me like it's being built from the default memtest86+ zipfile.

We also have the Kconfig option in coreboot to build memtest86+ as a secondary payload.  That works with no issue.

Below is my build output from the coreboot memtest86plus repo.  Hope this helps.
