AM6548: Testing emmc performance

Eric Hsieh4

Part Number: AM6548

Hi Ti,

From below link, https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Release_Specific_Performance_Guide.html#rt-kernel-performance-guide,

we can get the information about the emmc performance.

And we are trying to test writing 1MB file and get the performance on Linux RT SDK 07_01_00_18

As you can see below, the Max time and Min time have a big gap.

But in your result, it looks more stable. If there is any setting need to configure?

Below is the sample code we use to test write 1MB file.

Thanks.

Hi Eric,

I will take a look at this and get back in a day a two.

Best Regards,

Eric,

Can you share the code as a text file? The above is any image.

Eric,

From linux command prompt try the below commands:

cd /opt/ltp
./runltp -f ddt/emmc_perf_ext4 -P am654x-evm

Output: https://pastebin.ubuntu.com/p/P4wT5jrjWw/

NOTE: The above test case took almost an hour.

In the pastebin link search for iomode:write iomode:read

Typically 42MBps for write, read 180 MBps

Try and let me know.

Best Regards,
Keerthy

Hi Keerthy J

I just looked into the result you provide and few questions want to check with you.

1.What's the procedure of the test? something like "dd" or using fopen, fwrite as my test program?

2.What's your cpu frequency? 800MHz, 1GHz or 1.1GHz?

3.There are some test loops, all of them are with file size 100MB and srcfile 10MB, the difference is only buffer size. Correct?

So, the test is to write srcfile(10MB) into file size(100MB)?

|TRACE LOG|The application buffer size in bytes|102400|
|TRACE LOG|file size in MB|100.00|
|TRACE LOG|Iomode|write|
|TRACE LOG|srcfile size in MB|10.00|

4.I found almost the speed is about 38~42MB/s, but I still can see 18.35, 24.79 or 30.x MB/s. It looks like unstable. Isn't it?

800 MHz. This is the default frequency at which latest SDK boots.

Yes. That is correct.

I checked with MMC expert and yes there are outliers like 18.35, 24.7 etc. That is expected. So we take 38-42MB as the average.

Eric Hsieh4 said:

Definitely using dd. The test suite is pretty comprehensive. You can view the code: /opt/ltp/testcases/bin/ddt/blk/blk_device_filesystem_perf_test.sh

Hi Keerthy J,

I tried to run the test case. But it seems failed.

Could you please look into the log?

Do you have eMMC partitioned? It seems its not able to find any partitions for testing.

Hi Keerthy,

I looked into the pdf file and found the emmc on EVM can support up to HS400 mode.

And in k3-am65-mail.dtsi, the default setting for emmc is "mmc-hs200-1_8". It looks like am654 evm can only support HS200.

After I look into the emmc spec, the speed can up to 30MB/s at HS200 mode,

But according to your avg test result, it can up to 38-42MB/s.

Could you confirm about this? Thanks.

Eric

Hi Eric,

Those were the numbers from our standard test suite. I am not sure if they are
the conservative numbers from Micron but even our development team got
the same numbers. I confirm. If no other questions please click on verify answer.

Best Regards,
Keerthy
