1config BR2_PACKAGE_MEMTEST86 2 bool "memtest86" 3 depends on BR2_i386 || BR2_x86_64 4 help 5 Memtest86+ is a bootable standalone memory test program. 6 7 Buildroot does not support packages with a '+' sign in their 8 name, which explains why it is named memtest86 and not 9 memtest86+. 10 11 Memtest86+ is a utility designed to test whether your memory 12 is in working order. It repeatedly writes an enormous amount 13 of different patterns to all memory locations and reads them 14 back again and verifies whether the result of the read is the 15 same as what was written to memory. 16 17 Memtest86+ will only work on 32-bit or 64-bit x86 targets. 18 It boots as an i486 program and autodetects hardware. It can 19 be added to the grub2 boot menu by adding the following 20 lines to the bottom of /boot/grub/grub.cfg - note the use of 21 linux16. 22 23 menuentry "Memtest86+" { 24 linux16 /boot/memtest86+.bin 25 } 26 27 Other boot loaders will have similar requirements. 28 29 http://www.memtest.org 30
