@brief Encrypted and write data to the SPI flash chip using on-chip hardware flash encryption
@param chip Pointer to identify flash chip. Must be NULL (the main flash chip). For other chips, encrypted write is not supported. @param address Address on flash to write to. 16 byte aligned. Must be previously erased (SPI NOR flash can only write bits 1->0). @param buffer Pointer to a buffer with the data to write. @param length Length (in bytes) of data to write. 16 byte aligned.
@note Both address & length must be 16 byte aligned, as this is the encryption block size
@return
- ESP_OK: on success
- ESP_ERR_NOT_SUPPORTED: encrypted write not supported for this chip.
- ESP_ERR_INVALID_ARG: Either the address, buffer or length is invalid.
- or other flash error code from spi_flash_write_encrypted().
