Tool/software: Linux

Hi Sir 

we followed the suggestion as below 

       e2e.ti.com/.../745243

1. removed the dra7-dspX-fw.xe66 files from the filesystem.

2. After that we re-tried  the ltp test, it still failed.

    Hi, Yimin,

    Ok. The failure doesn't have anything to do with DSP is running or not. It simply means the free memory isn't enough. You can take a look at the script files and it is also shown in the log that the script checks if $expected_memory is greater than $min_mem_size. It not, it terminates and hence failed.

    cmdline="source 'board_requirements.sh'; get_acceptable_[ 1423.837449] LTP: starting MEMORY_S_FUNC_MEMTESTER_1pct_1time (source 'functions.sh'; run_memtest 1 1)
    memory_size; min_mem_size=`echo "$expected_memory * 0.95 / 1" |bc`; [ $(free | grep Mem:| awk '{print $2};') -gt $min_mem_size ]"

    In our system test, we only test 3 cases: 1pct_1time, 10pct_1time, and 50pct_1time.

    In your logs, you failed when running 80pct_1time and got "stop alarm was received" message , but I am passing. I suspect it may have something to do with the "-t 1h" which I didn't specify.

    If you still have issues with running ltp test. I suggest you search on internet and send quetions to ltp open forum. TI doesn't own ltp test but take it from open source.

    If you don't have any issues wit TI software, please click "Resolved".

    Hi Sir

    You mentioned  “In our system test, we only test 3 cases: 1pct_1time, 10pct_1time, and 50pct_1time. ”

    I want to know how to do test the memory function in TI test plan.

    Would you give me the correct setting file and command by using LTP from TI?

    Then we can use the same test to test our AM57x board for memory function verification.

    Thanks

    Hi, Yimin,

    As I memtioned TI only test 3 cases, and they are 1pct_1time, 10pct_10time (correction from my previous post), and 50pct_1time.
    We are using automation, so it isthe same commands as in the ltp script file, but different format. We execute each test separately and not in group in a file as what you did.

    We don't run CHECKSIZE test. I suspect your issue is because the free memory is less than expected minimal. If you want to run it, I suggest that you check if free memory is greater than the min_mem_size. I believe in the script file, the min_mem_size is set to $expected_memory. If you still have issue running CHECKSIZE, debug print these values in the script file always help. Once you find out the relationship between the values used in the script, you should know what value to use per your system environment.
