- Mon Jun 04, 2018 9:58 am #76268 Just an FYI thing, could help people out.

On upgrading my projects to the latest SDK, I was annoyed that I had to upload the esp_init_data_default.bin file to different locations dependent on flash size/module I was using.

I have modules in the field that need to be upgraded, and I cannot always guarantee that they're the same flash sizes either, or dont want to have that problem down the line anyway.

As such, I just added the init data to user_rf_pre_init() with the following code, if its not found then it'll update itself:

Code: Select allconst uint32 esp_init_data_default[] = {
  0x02040005,0x02050505,0x05040005,0x05050405,0xFFFDFE04,0xE0F0F0F0,
  0x0AE1E0E0,0x00F8FFFF,0x4E52F8F8,0x3840444A,0x01010000,0x03030302,
  0x00000001,0x00020000,0x00000000,0x00000000,0x000A0AE1,0x00000000,
  0x93010000,0x00000043,0x00000000,0x00000000,0x00000000,0x00000000,
  0x00000000,0x00000000,0x00000000,0x00000000,0x00010000,0x00000000,
  0x00000000,0x00000000};

void user_rf_pre_init() {
  enum flash_size_map size_map = system_get_flash_size_map();
   uint32 rf_cal_sec = 0, addr, rfCalData;
  os_printf("\nUser preinit: ");
   switch (size_map) {
      case FLASH_SIZE_4M_MAP_256_256:
         rf_cal_sec = 128 - 8;     
         break;

      case FLASH_SIZE_8M_MAP_512_512:
         rf_cal_sec = 256 - 5;
         break;

      case FLASH_SIZE_16M_MAP_512_512:
      case FLASH_SIZE_16M_MAP_1024_1024:
         rf_cal_sec = 512 - 5;
         break;

      case FLASH_SIZE_32M_MAP_512_512:
      case FLASH_SIZE_32M_MAP_1024_1024:
         rf_cal_sec = 1024 - 5;
         break;

      default:
         rf_cal_sec = 0;
         break;
   }
 
  addr = ((rf_cal_sec) * SPI_FLASH_SEC_SIZE)+0x1000;
  spi_flash_read(addr, &rfCalData, 4);
  if (rfCalData == 0xFFFFFFFF) {
    os_printf("Storing rfcal init data @ address=0x%08X\n", addr);
    spi_flash_erase_sector(rf_cal_sec);
    spi_flash_write(addr, (uint32 *)esp_init_data_default, sizeof(esp_init_data_default));
  } else {
    os_printf("RF init data present\n");
  }
}

- Wed Jun 06, 2018 4:30 am #76317 Update to this:
