A couple of things.

1) End address should be the last byte of the sector.
2) 8MB of flash based on 0xfe000000 should end at 0xfe7fffff. Your 
address range is behind this.
3) In previous message you listed your configuration having 2 banks. Do 
you really have two banks of flash? (each having 8MB? with a total of 
16MB) If not correct that two 1 bank.
4) Check the syntax of erase command. You can specify the erase range in 
terms of block numbers instead of addresses as well.
