TMS320F28379D: How to change the entry address that is specified in the .cmd file from software so that it boots from a different flash sector after reset

In your new application you would have changed the memory region to sector G from D. So in any case you need to manually edit the cmd file, so you can update the entry address as well.

In F2837 device only one flash address is supported which is ox80000. In later devices we have provided more flexibility with the address options.

Hi Baskaran. Thank you for responding! If both applications have two different entry addresses, how can the device boot from Flash sector G and not from sector D after a reset?

you need to have a constant code which determines the latest image and start executing that.

A similar mechanism was implemented to support Live firmware upgrade in F28004x. The app not will give you some idea about how to implement the above in your application - https://www.ti.com/lit/pdf/spruiu9
