Function Documentation#

halBootloaderGetType#

BlBaseType halBootloaderGetType (void )

Returns the bootloader base type the application was built for.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Returns


halBootloaderGetInstalledType#

BlExtendedType halBootloaderGetInstalledType (void )

Returns the extended bootloader type of the bootloader that is present on the chip.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Returns

  • the extended bootloader type of the bootloader that is present on the chip.


halGetBootloaderVersion#

uint16_t halGetBootloaderVersion (void )

Returns the version of the installed bootloader, regardless of its type.

Parameters
TypeDirectionArgument NameDescription
voidN/A

Returns

  • Version if bootloader installed, or BOOTLOADER_INVALID_VERSION. A returned version of 0x1234U would indicate version 1.2 build 34


halGetExtendedBootloaderVersion#

void halGetExtendedBootloaderVersion (uint32_t * getEmberVersion, uint32_t * customerVersion)

Return extended bootloader version information, if supported.

Parameters
TypeDirectionArgument NameDescription
uint32_t *N/AgetEmberVersion

If specified, we will return the full 32bit ember version for this bootloader. Format is major, minor, patch, doc (4bit nibbles) followed by a 16bit build number.

uint32_t *N/AcustomerVersion

This will return the 32bit value specified in CUSTOMER_BOOTLOADER_VERSION at build time.

This API is not supported for EM2XX chips and only returns extra information on bootloaders built on or after the 4.7 release.
