Re: Permanently mmap-ed partition?
How about if the size of the mmap-ed region is big, say 1MB? Does it have any effect?

Permanently mmap-ed partition?
Every example usage of esp_partition_mmap I see is followed by a spi_flash_munmap a few lines later. However,
is there any harm in mmap-ing a partition at the beginning of app_main, using a global variable for out_ptr, and not munmap-ing it for the lifetime of the app?
