i am using USB to directly on-board programming the AT91SAM7S MCU (Download software is ‘sam-ba v2.9’ )
However i found that some MCUs' erase time will take up to several seconds (From the AT91SAM7S MCU spec we can see ‘Full Erase Time: 10 ms'). So i am afraid if there's any problem on the MCU.

Please kindly advice what are the possible causes to take so long time to Erase the MCU?
