Hi,

https://linux.die.net/man/8/memtester

We have the memtester application as part of the default file system.

Ex: testing 1GB

memtester 1G
memtester version 4.5.1 (64-bit)

pagesize is 4096
pagesizemask is 0xfffffffffffff000
want 1024MB (1073741824 bytes)
got 1024MB (1073741824 bytes), trying mlock ...locked.

Hi Keerthy:

Now we can execute memtester test in our board, thanks a lot.

May I ask another question about how to test lpddr4 in u-boot during bootup process?

Because TDA4VM seems to support LPDDR4 test/frequency handshake in u-boot from bootup log information.

Can we verify lpddr4 setting/performance in u-boot?

Hi,

Yes: https://github.com/ARM-software/u-boot/blob/master/doc/README.memory-test

A note of caution that this will be very slow in U-Boot.
