Dear Simon,

We do have an 'sf test' command. I think it is useful, particularly if it measures speed as well.
I tend to agree with Hans - this should normally be implemented in a script, or, if reallyneeed (but I can't ssee why this would be necessary) in board specific code.
If added as a generic feature, then there should be options to select which range of the device to use for testing. It may be interesting to test specific areas (like at the assumed end of the device), or at least to be able to respect existing partitions etc.
But still - I can't see why this would be needed - plain reading and writing to the device or even to a file in a file system should perform the same task.
Best regards,
Wolfgang Denk
