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, Alder, Miami, Dakota, Maple)

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.

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.

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.

Model-Matrix

Daily updated index of the presence, path and size of this partition for each model. Last update: 2024-07-15 06:41 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) label in the Model column shows which CPU is meant for models with multiple Linux instances.
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.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
