Part Number: AM5728

Tool/software: Linux

Hi Sir

We used processor SDK to do LTP memory test tool in AM5728 GPEVM and found it tested failed in latest SDK.

Below is the information

Linux Kernel 4.14.67+ (2018 LTS) -> 05_01_00_11 SDK (kernel version is 4.14.67) -> Test Failed

Linux Kernel 4.1.13+ (2015 LTS) -> 02.00.01 SDK (kernel version is 4.1.13) -> Test ok

below is the log message

Yimin,

I've reproduced your results and will be looking into this further. Thanks for reporting it to us.

Yimin,

The test checks that total memory is >= than a minimum defined in board_requirements.sh as below:

# Return expected memory size (in kB) for running platform

case $MACHINE in
omapl138-lcdk)
expected_memory=123100 ;;
k2g-ice)
expected_memory=383992 ;;
beaglebone-black)
expected_memory=495788 ;;
am335x-evm)
expected_memory=1015116 ;;
k2hk-evm|k2l-evm)
expected_memory=1415144 ;;
am43xx-gpevm|am57*|dra71x*|dra72x*|k2g-evm)
expected_memory=2065756 ;;
k2e-evm)
expected_memory=3494192 ;;
am65*|dra7xx*|dra76x*)
expected_memory=4123488 ;;
esac

I believe we are carving out some memory for non-Linux usage (most likely for DSP IPC) and hence total memory is less than value defined above.

This test is not part of our test plan as there is no requirement for specific amount of Linux memory. Different boards have different amounts of memory, for example.

You can run memtest by specifying the actual test case to avoid running all tests specified in the scenario file which are executed in sequential order.

A command like the one below should work better:

/opt/ltp/runltp -P am57xx-evm -f ddt/memtest -s MEMORY_L_FUNC_MEMTESTER_50pct_1time

Or you could go in and tweak board_requirements.sh with a more appropriate memory size to use.

I hope this is helpful to you.
