following output has compiled by using ARM.

compiling with GCC_ARM gives following output (seems to work correctly)

it seems that used filesystem does not have any impact to functionality only used complier has impact to the output

Can you try wiping the storage device by pressing BUTTON1? I've seen before when the storage device gets in a bad state on previous runs the behavior can persist across new binaries.

Do you have this commit as well? Had previously fixed it for both @geky and myself.

Also which block device are you using?

[SamiLappalainenArm]

I have used block device definition shown below:

SDBlockDevice bd( MBED_CONF_SD_SPI_MOSI, MBED_CONF_SD_SPI_MISO, MBED_CONF_SD_SPI_CLK, MBED_CONF_SD_SPI_CS);

by pressing Button1 (SW2) before reset does not help:

What's your Mbed OS and Filesystem example commit hash? We can try to debug locally.

@kegilbert I believe it's the same as https://github.com/ARMmbed/mbed-os-example-filesystem/issues/39#issuecomment-374144985

[SamiLappalainenArm]

above comment is correct related to used commit hash.

[kegilbert]

The fix here: 29a91bf is only on master it looks like, it needs to be cherry picked to the oob branch.

@geky

[SamiLappalainenArm]

this problem was solved after applying above fix
