      Memtest86+ is a bootable standalone memory test program.

​

      Buildroot does not support packages with a '+' sign in their

      name, which explains why it is named memtest86 and not

      memtest86+.

​

      Memtest86+ is a utility designed to test whether your memory

      is in working order. It repeatedly writes an enormous amount

      of different patterns to all memory locations and reads them

      back again and verifies whether the result of the read is the

      same as what was written to memory.

​

      Memtest86+ will only work on 32-bit or 64-bit x86 targets.

      It boots as an i486 program and autodetects hardware. It can

      be added to the grub2 boot menu by adding the following lines

      to the bottom of /boot/grub/grub.cfg - note the use of linux16.

​

      menuentry "Memtest86+" {

         linux16 /boot/memtest86+.bin

      }

​

      Other boot loaders will have similar requirements.
