Memtester how to use? how to use system level tester to test DDR5,LPDDR5,UFS3.1

Memtester download address: http://pyropus.ca/software/memtester/ ,There are source code installation, deb, rpm, etc.

The source code has been compiled, just make it under memtester android or memtester linux.

Memory testing can be performed on ARM platforms, we provide Mediatek and Qualcomm high-frequency platforms motherboards.

Usage: memtester [-p physaddrbase] [B|K|M|G] [loops]

Such as: memtester 28G 3# Test 28G memory 3 times.  

memtester version 4.3.0

Because both the system operation and the operation of this tool require memory, all the memory cannot be tested. You can use the free command to check how much memory space is left in the system before testing. Advanced points can be tested from the memory address with the -p parameter.

Loop1/3:

Stuck Address : ok          

Random Value : ok  

Compare XOR : ok  

Compare SUB : ok  

Compare MUL : ok  

Compare DIV : ok  

Compare OR : ok  

Compare AND : ok  

Sequential Increment: ok  

Solid Bits: ok          

Block Sequential: ok          

Checkerboard : ok          

Bit Spread: ok          

Bit Flip: ok          

Walking Ones: ok          

Walking Zeroes: ok          

8-bit Writes: ok  

16-bit Writes: ok  

If all the results are OK, the memory is normal.

For some unneeded test projects, you can modify the memtester.c file, comment out some content, and then re-make it.
