SPIFFS Example

Starts a FreeRTOS task to print “spiffs write/read demo”. As you run the example, you will see the log :

INFO (5)[main.c:  94] --> spiffs write/read demo <--
INFO (25)[main.c:  71] spiffs mount success
INFO (33)[main.c:  88] --> Hello world <--

How to use?

//Add Configuration
spiffs_config cfg = {
   .phys_size = 0x00047000,                 // use spi flash size
   .phys_addr = DEMO_HOSAL_FLASH_TEST_ADDR, // start spiffs at start of flash
   .phys_erase_block = 4096,                // physical sector size
   .log_block_size = 4096,                  // logical sector size (Must be an integer multiple of physical sectors)
   .log_page_size = LOG_PAGE_SIZE,          // logical page size
   .hal_read_f = spiffs_read_flash,         // flash read function
   .hal_write_f = spiffs_write_flash,       // flash write function
   .hal_erase_f = spiffs_erase_flash,       // flash erase function
};

//SPIFFS Mount
int res = SPIFFS_mount(&fs,
                       &cfg,
                       spiffs_work_buf,
                       spiffs_fds,
                       sizeof(spiffs_fds),
                       spiffs_cache_buf,
                       sizeof(spiffs_cache_buf),
                       0);
