Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE, SYSCONFIG

Hi, in my project we got a new requirement like we need to secure the memory of our code so we are using DCSM reference code i.e. C:\ti\c2000\C2000Ware_4_02_00_00\driverlib\f2837xd\examples\cpu1\dcsm 

 but am not understanding how we are going to set password in OTP region so that it could compare our key (the key which we will write in code from user) to unlock the secured memory 

please tell me the process how to set a password in OTP region to secure memory

regards

    Muni,

                  It is not possible to explain how DCSM works in a e2e post. If you have thoroughly read section 3.13 Dual Code Security Module (DCSM) in www.ti.com/lit/SPRUHM8  but still unclear about how the DCSM works, I suggest you look at the topic in C2000 Academy. That page also points you to informative application Reports.

    I suggest you familiarize yourself with the SYSCONFIG tool. It is the easiest way to configure the DCSM.
