Part Number: TMS320F28386D

Does F28386D have the type of RAM that do the simulation reset, the value in that RAM will remain as before reset.

The simulation reset will not reset the value of that RAM region.

RAM content does not get cleared on SIMRESET for XRSn. But, please note that all the variables in code get initialized by .cinit. function.

Only on power on reset, RAM content get cleared by BOOTROM. All other reset should retain the RAM content.

It may some concepts make me confused me.

As I use the debuger reset, the global variable suach as RxBuf arrary will reset as all 0.(I didnot initialize this arrary)

As I mentioned, in case of EABI format, all the variables get initialized by .cinit function (even if it's not been initialized in the code).

Yes, I got you.

And use the pointer to store the value successfully.
