I am running the mk_mx28_sd as described in 5.1.3.1 of the users guide. I am able to determine my SD card is /dev/sdb via the method described. However after removing the card as instructed and running ./mk_mx28_sd /dev/sdb it does nothing (no prompting) and just returns immediately to the shell prompt.
I think I am missing something obvious but at a loss to see it right now. Any pointers would be appreciated.
TIA
