BeagbleBone Black flash access trace

I need to make a trace files of flash access in BBB.(including block and page number of access and the operation of access R/W)
There is a windows tool called DiskMon that does this job in windows based systems. Is there any tool that I can use in linux?
I ask this question in another beaglebone related forum, and someone suggest me blktrace. I installed this tool but I can’t use it as it needs the name of the block storage media to monitor. I couldn’t find any sda file under dev directory. I tried the command with /dev/mmcblk0 as input but it doesn’t work.
Please help me with this issue I need this trace file for my project. Any help will be appreciated.
