flash write with defined address

[milav]

Hello,

I want to save Image data which are come from the central device to flash memory of peripheral side.

The image data size is vary from 3KBytes to 10KBytes.

i want to save at particular address so that application code can not overwrite that address.

means in flash write example... addr = (uint32_t *)(pg_size * pg_num); flash_word_write(addr, (uint32_t)patwr);

i want particular 32-bit number instead of addr.

please correct me if i m wrong.

thank you.

I am afraid that I do not quite understand what you want to do. If you're going to have the SoftDevice enabled then you need to use ble_flash_word_write where the first argument is a pointer to a 32-bit address.

i Want to stored image data to particular known address of flash memory...

i just want to know in which address i stored this image data. so the memory architecture like this...

first => soft device second => application third => image data

so i want to know the starting address of third partition.

Thank you

You want to know the application end address? This is define by the memory settings in the application project.

What is the maximum bytes we can store in internal flash memory along with soft-device and application?

any rough estimate ?

That will entirely depend on the size of the application and which SD version you are using.
