Hi everyone...

I'm testing 'Safe Copy Code' function of DCSM

so I import 'dcsm_scc_reset_cpu01' Project into my workspace and build with Flash Build Configuration..

and run application..

but I think .. SafeCopyCodeZ1(32, (Uint16 *)0xC000, (Uint16 *)0x80000); <-- this line doesn't work

I checked both of memory area... but 0xc000 region isn't changed from '0'

and I don't understand Why Timer function is need?? in this example..

anyone know about this??

and here is my DCSM Z1 settings..

Hi,

What does the function return?

Are you copying from EXEONLY memory to EXEONLY memory?

Also please make sure that when you are checking the content into the RAM after copy, you unlock the zone because EXEONLY RAM can not be read without unlocking the zone.

thanks for reply

0xC000 --> GS0RAM

0x80000 --> Sector A

no... Sector A is Execute only sector.. and GS0RAM is not Execute only RAM

But this code is Example code from controlSUITE.. I've not changed anything...

and also Test board was Unlock State..

Hi,

no... Sector A is Execute only sector.. and GS0RAM is not Execute only RAM

SafeCopyCode function should be used for copying code from EXEONLY Flash sector to EXEONLY RAM. GS0RAM is nonsecure RAM and this function does not allow copying code to nonsecure RAM.

What is the name of example code in controlSUITE which you are using?
