Can the data be stored to 640K FLASH of JN5189 when the program is running?

Thanks for your time.

Hi,

I hope you are doing great.

Depending on the example that you are running on. The code will need flash memory for values that needs it.

For example: Look at the JN-AN-1243 Release notes and you will find the Memory Usage for that example.

Regards,

Mario

Hi,

Thanks for your reply.

I am sorry, I didn't find anything about using flash in the JN-AN-1243 Release notes. 

The 640K flash is used to load the code, whether the remaining space of it can be used as ordinary flash? Can some data generated during the running of the program be stored in flash while the program is running?

Look forward to your reply!

Hi,

After all the compilation process you could look a the information about the memory that the code needs.

Please look at the flash demo driver that we provide in the SDK.
