Hi Mark,

Yes I already know for the command "dir flash", but actually the questions is the Result of "dir flash" . I Have the same number with you capture were 1621966848 bytes. Were the result "1621966848" same with 2 GB Flash, i dont think so. Because 2 GB convert to bytes mean around the value 1862645149 bytes

Like I said before in beginning post, Is the sum of 1621966848 (flash) and 248354816 (crashinfofiles) became a total flash
