From another Forum post (http://e2e.ti.com/support/microcontrollers/tms320c2000_32-bit_real-time_mcus/f/171/p/111512/395230.aspx#395230), David Foley mentioned that flash sectors are not entirely independent of each other when erasing.
Please let us know what sectors in the F28335 are balanced with each other. I need to know this information to know how to allocated sectors so that they are truly erase-independent.
Thank you!

David Foley said:... The F2808 device uses a balanced sector flash architecture. This means that if the flash bits in sector D are left in a depleted state because power was lost during erase the image in sector A could be compromised. If you have to rely on booting from sector A, and there is a chance that power can be lost during erase, you shouldn't erase sector D. Likewise sectors B and C are balanced with each other.
