Details

CDT is the Qualcomm platform Configure Data Table partition. It stores platform information and memory parameters.
The label of this partition is originally named 0:CDT, which is an invalid article name in Mediawiki.

CDT is stored in 1 or 2 instances and is loaded by the SBL.
The size, location and instances differ each platform, see below.

Multi-EVA boot on Qualcomm-ARM:

Hawkeye

On Hawkeye both 256 KB sized CDT partitons are located on the eMMC, the second instance is named CDT_1.

See the SBL article for the partition table.

Dakota

On Dakota only a single *hidden* 256 KB sized CDT partiton exists. It is located in mtd2.

See the SBL article for the partition table.

Dependencies

Daily updated index of all dependencies of this partition. Last update: GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Model-Matrix

Daily updated index of the presence, path and size of this partition for each model. Last update: 2024-12-21 07:02 GMT.
Showing all models using this partition. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.
