i.MX 95 A1 to B0 Silicon Revision Update Guide
Introduction
This article describes the compatibility changes related to NXP's silicon modification from A1 to B0 on the i.MX 95 System on Chip (SoC). The following sections highlights the software and hardware compatibility, and their impact on product integration.
Revision Compatibility
The transition from silicon revision A1 to B0 does not impact carrier board compatibility. All i.MX 95-based modules (Verdin, Aquila, and SMARC) remain fully compatible with their respective carrier boards.
End-of-Life Notice The i.MX 95 Verdin EVK has reached end-of-life (EOL). Limited units may still be available, but the EVK is not recommended for new designs.
Check the comparison page to learn about development options with NXP i.MX 95-based products. The EVK BSP is not maintained by Toradex, and full Torizon OS support is only available on production-ready SoMs. For details, see the i.MX 95 Verdin EVK product page.
In the following tables you can find the compatibility between the modules revision and Toradex's available OS (BSP and Torizon OS). As new hardware revisions are introduced, certain changes may bring breaking compatibility with previous software releases. To minimize disruption, Toradex follows a successive support strategy to transition from A1-based to B0-based products, where:
- Existing hardware remains supported up to a defined release.
- New hardware revisions gain support from the following release onward.
This approach provides a practical transition window between hardware and software versions, minimizing disruption as customers migrate to newer releases.

Footnotes
-
The Verdin iMX95 V1.1A revision has limited support from BSP 7.6.0 onward. BSP 7.8.0 and later support V1.1B by default with NXP ELE firmware 2.0.6 or later; using V1.1A with these releases requires rebuilding the image with a compatible earlier ELE firmware. Additional limitations may apply in future releases. Suitable for development and evaluation only; not recommended for volume production. ↩
-
The SMARC iMX95 V1.1A revision is not officially maintained from BSP 7.6.0 onwards, resulting in limited support. Some limitations may arise in future releases. This setup is suitable for development and evaluation purposes and is not recommended for volume production due to the sample status of this version. ↩
