ram test

1. pattern test

 memtest :  used it in bootloader for data/address bus test

  http://www.barrgroup.com/Embedded-Systems/How-To/Memory-Test-Suite-C

  http://www.barrgroup.com/code/memtest.zip.

2.  stress test

  memtester  : 

  http://blog.csdn.net/fybon/article/details/52982082

  it is similar to QCOM's QMESA

  https://github.com/json-pu/AndroidEatMemory    //low memory test 

// cd m/system/utils/memtest_mode

run stress test for DRAM as below.

1 phone turn off

2. Plug in charger
3. Wait for charge only mode/screen
4. Press vol up, up , down, down, up, up, down , down, and power key long press
5. Phone screen will move to RAM test mode
6. Press power key for run/auto memory allocation. 

put the phone into temp chamber with set to 55C or 60, and -20C, respectively, until test numberof cycle reaches up to over 10k, for each temperature.

we can use these cmd to run memtester in different performance status .

3. performance test 

  bw_mem  : 

  it is from LMbench :http://blog.csdn.net/fybon/article/details/52313955

  http://www.bitmover.com/lmbench/

BTW:  there is another useful tool from LMbench :lmdd - move io for performance and debugging tests

refer to : http://www.bitmover.com/lmbench/lmdd.8.html

we can use this batch with lmdd for storage (sdcard or data ...) performance test !
