TMS320F28384D: Program secured flash sectors.

Part Number: TMS320F28384D

Hi champs,

If Zone 1 password enabled, all flash sectors and LS RAM assigned to Zone 1. When we execute flash API on LS RAM(secured), is it necessary to unlock device before erasing / programming flash sectors?

I ask this question because according to TRM, software gets full flash access when executed inside secure memory. However, my customer needs to unlock DSP device first to program secured flash sectors without problem.

Please advise your comments, thanks for help.
