• Use spi_flash_erase_sector to erase the sector first, then call spi_flash_write to write data in. For example, uint32 data[M]; // TODO: fit in the data spi_flash_erase_sector(N); spi_flash_write(N*4*1024, data, M*4); (3) Compile application program, generate firmware and burn it into ESP8266 module.
