NVIDIA Tegra Linux Driver Package Development Guide 32.1 Release |
Device Attributes | Values | Description |
device type | sdmmc_boot sdmmc_user sata | (Required) Specifies the type of device. eMMC boot0 and boot1 hardware partitions are treated as a single sdmmc_boot entry. |
Instance | 0-3 | (Required) the device instance. 0 for SATA. 3 is typical for eMMC. |
Attribute | Values | Description |
name | For a complete list of pre-defined names, see Default Partition Overview. | (Required) Specifies a name for the partition. The name can have a maximum of 36 characters. There are three kinds of partitions: mandatory, optional, and user defined. All mandatory and optional partition names must be associated with the specific partition type. All user specified partition names must be associated with partition type “data”. |
type | For a complete list of types, see the Default Partition Overview. | (Required) Specifies the type of partition. Certain partition types are valid only when they are associated with specific partition names. |
oem_sign | True False or attribute not present | Append generic signature header to the binary and perform OEM signing on that. Append NULL signature header to the binary and perform NULL signing on that. |
Element | Values | Description |
allocation_policy | sequential | Specifies the type of allocation policy. Sequential partitions begin immediately after the preceding partition. (The legacy “absolute” allocation policy has been deprecated.) |
filesystem_type | basic | The basic filesystem_type specifies “raw” partition. (The legacy “ext2” filesystem has been deprecated.) |
size | <byte size> | (Required) Specifies the size of the partition in bytes. Decimal and hexadecimal values are valid. The partition size may be equal to or larger than the size of the file to be written to the partition. Specifying a larger size allows the file size to increase later without requiring the partition configuration file to be modified. If the partition size specified is less than an erase block size, it will align itself to the partition erase block boundary. The size property of the secondary GPT partition, which is defined at the end of each device, must always be 0xffffffffffffffff. Tegraflash calculates the size automatically, the preceding partition is extended to fill any free space before the secondary GPT. |
file_system_attribute | 0 | Not implemented. |
allocation_attribute | 0x8 0x808 | Must be 0x808 for the partition immediately preceding the secondary GPT. |
percent_reserved | 0 | Reserved for future use. |
filename | <filename> or empty | Specifies the name of the file to write into the partition. If the filename is empty, no data is written to the partition. |
