Search for, verify, and apply firmware updates.
reboot is true, then this function does not return.| tag | The tag (name) of the update image in the flash filesystem. |
| dry_run | Only verify data and operations. Do not write to flash or reboot. |
| reboot | If true, reboot after the update has been successfully written. |

| 1 | on success, if a firmware update was applied and a reboot is required. |
| -EINVAL | if an argument is invalid. |
| -EIO | if an I/O error occurs. |
| -ENOENT | if the image is invalid an image named tag cannot be found. |
| -ENODEV | if the current slot cannot be determined or a device is not ready. |
| int tt_fwupdate_complete | ( | void | ) |
Called on the completion of the fwupdate operation, disables the spi mux if initialized in tt_fwupdate_init
| 0 | on success, if the spi mux was able to be set |
| int tt_fwupdate_confirm | ( | void | ) |
Confirm that the current firmware has booted successfully.
| 0 | on success. |

| int tt_fwupdate_init | ( | const struct device * | dev, |
| struct gpio_dt_spec | mux ) |
Set the external flash device and set the passed spi mux (if not null) to allow communication with the spi.
| dev | The pointer to the external flash device to use. |
| mux | The spi mux to set and disable on start and completion of the fw update operations. |
| 0 | on success, if the spi mux was able to be set |
| int tt_fwupdate_is_confirmed | ( | void | ) |
Check if the currently running firmware has been confirmed.
