CONFIG_BUILD_OUTPUT_UF2_FAMILY_ID

UF2 device family ID

Type: string

Help

UF2 bootloaders only accept UF2 files with a matching family ID.
This can be either a hex, e.g. 0x68ed2b88, or well-known family
name string. If the SoC in use is known by UF2, the Family ID will
be pre-filled with the known value.
