Expand description

@brief Read data from the partition without any transformation/decryption.

@note This function is essentially the same as \c esp_partition_read() above. It just never decrypts data but returns it as is.

@param partition Pointer to partition structure obtained using esp_partition_find_first or esp_partition_get. Must be non-NULL. @param dst Pointer to the buffer where data should be stored. Pointer must be non-NULL and buffer must be at least ‘size’ bytes long. @param src_offset Address of the data to be read, relative to the beginning of the partition. @param size Size of data to be read, in bytes.

@return ESP_OK, if data was read successfully; ESP_ERR_INVALID_ARG, if src_offset exceeds partition size; ESP_ERR_INVALID_SIZE, if read would go out of bounds of the partition; or one of error codes from lower-level flash driver.
