Dahlia Carrier Board V1.1D Compatibility with Verdin iMX95
Based on the available documentation, I can provide some insights regarding the Dahlia Carrier Board compatibility with Verdin modules, though specific information about V1.1D and Verdin iMX95 compatibility is not explicitly covered in the sources.
Hardware Compatibility Considerations
The Verdin Carrier Board Design Guide indicates that Verdin modules feature standardized interfaces that are compatible between different modules(1). This standardization suggests that newer Verdin modules like the iMX95 should maintain compatibility with carrier boards designed for the Verdin family(1).
Known Dahlia Carrier Board Issues
The documentation reveals several important errata for Dahlia Carrier Board versions that affect compatibility with newer Verdin modules:
Power Management Compatibility
- Dahlia V1.0B: Has a critical issue with the CTRL_FORCE_OFF_MOCI# signal having a pull-down instead of pull-up resistor(2)
- Dahlia V1.0C: Implements a workaround by removing R96, but this disables the “kill-feature” entirely(3)
- Dahlia V1.1A: Fixes the CTRL_FORCE_OFF_MOCI# issue(3)(2)
The errata specifically mentions compatibility concerns with newer Verdin modules that implement the CTRL_FORCE_OFF_MOCI# as an open-drain signal(2).
BSP and Device Tree Overlay Support
The Reference Documentation shows device tree overlay support for Verdin iMX95 starting from BSP version 7.3.0(4). Available overlays include:
- DSI to HDMI adapter support:
verdin-imx95_dsi-to-hdmi_overlay.dtbo(4)
- Capacitive Touch Display 10.1" DSI:
verdin-imx95_panel-cap-touch-10inch-dsi_overlay.dtbo(4)
- OV5640 Camera:
verdin-imx95_ov5640_overlay.dtbo(4)
Design Resources Available
The Dahlia Carrier Board design data is available in Altium Designer format, including schematics, layout, and component libraries(5). This allows for verification of compatibility and any necessary modifications.
Recommendation
To get definitive confirmation about Dahlia Carrier Board V1.1D compatibility with Verdin iMX95, I recommend:
- Using the
tdx-info command to get detailed information about your specific hardware setup: Getting Device Information with Tdx-Info | Toradex Developer Center
- Reviewing the complete Dahlia Carrier Board design files available at the carrier board design resources
- Ensuring you’re using BSP 7.3.0 or later for proper Verdin iMX95 support
The standardized Verdin interface design suggests compatibility should exist, but specific validation with your exact hardware combination would be prudent.
