memtest

glasgow run memtest

Run a simple memory test procedure to diagnose memory issues. Our patented memtest67™ algorithm works as follows:

• For each pattern in (Const0, Const1, Alt01, Alt10, PRBS) do:

  • For each sequential block of specified size in the specified region, do:

    • Write pattern sequence to memory block

    • Read memory block and compare with pattern sequence

usage: glasgow run memtest [-h] -c INDEX [-a HEX-ADDR] [-b HEX-ADDR] [-s SIZE]
                           [-n COUNT]

-h, --help

show this help message and exit

-c {0,1}, --channel {0,1}

memory channel (one of: 0, 1)

-a <hex-addr>, --start-addr <hex-addr>

start of region (default: zero)

-b <hex-addr>, --stop-addr <hex-addr>

end of region, exclusive (default: 64 MB)

-s {2,4,8,16,32,64,128,256,512,1024,2048}, --block-size {2,4,8,16,32,64,128,256,512,1024,2048}

block size (power of two, 2..2048, default: 2048)

-n <count>, --cycles <count>

repeat memory test COUNT times
