Otherwise, ocassionally see errors like this: Flashing sparse image at offset 2078720 Flashing Sparse Image sdhci_send_command: Timeout for status update! mmc fail to send stop cmd write_sparse_image: Write failed, block #2181088 [0]
This does not affect the actual writing speed, which is controlled by the default value: CONFIG_SDHCI_CMD_DEFAULT_TIMEOUT
It only increases the retries when reading: SDHCI_INT_STATUS to avoid the timeout error.
