Hi,

The FDS module sets the flash bounds in the function flash_bounds_set() in the file fds.c

Best regards

Hi Jared,

How do we ensure that the flashlog and application data don't overwrite each other?

For example, in the definition for nrf_log_backend_flash_erase, we see:

nrf_fstorage_erase(&m_log_flash_fstorage, RUNTIME_START_ADDR, NRF_LOG_BACKEND_PAGES, NULL)

This seems to indicate that we clear flash pages starting from the runtime start address. However, I didn't see a way to specify which addresses the FDS will use.

Thanks for any clues!

Hi,

Yes, as long the flashlog and application data don't overwrite each other.

Best regards

Jared
