Basically what I did after creating the mmcsd0s3 partition, I format it right away with newfs. So I re-created the setup to clear things out. This time having mmcsd0s3 partition and mmcsd0s3a in freebsd-ufs type. You can see below sequences of procedures. I deleted the existing mmcsd0s3 partition first and then create a new one in the same 8GB size.

The TRIM activity were observed the same as previous but having the mmcsd0s3a along with mmcsd0s3 and mmcsd0.
