What practice did Mohamed recommend when adding boards or drivers for a Zephyr-based project to avoid maintaining a fork of Zephyr?

A Fork Zephyr and maintain your own customized Zephyr tree for each product.

B Create out-of-tree boards, drivers, and libraries in your own repository instead of forking Zephyr.

C Patch the Zephyr upstream core directly in your product repository and distribute that patched core.

D Abandon Zephyr and use a vendor proprietary SDK to avoid dealing with Zephyr updates.

E Embed the entire Zephyr source in the firmware binary so you can modify it locally.

According to the panel, what is the recommended approach to testing embedded software early in development before hardware is available?

A Simulate as much as possible and decouple drivers so the application can run in a simulated or host environment (e.g., native_posix, QEMU).

B Wait for physical hardware prototypes and only then begin testing to ensure real-world accuracy.

C Rely primarily on manual, in-field testing once customers start using the product.

D Skip unit and board-level testing and focus only on end-to-end system tests on final hardware.

E Use static analysis only and avoid runtime simulation since it’s unreliable.

When choosing a programming language for a new microcontroller project, what main criterion did the speakers recommend you base the decision on?

A Base the choice primarily on your team's expertise and the project’s constraints; C/C++ remain valid and Rust is promising but currently less supported by vendors.

B Always choose Rust for microcontroller projects because its compiler eliminates all runtime bugs.

C Always choose modern C++ for microcontrollers to get object-oriented benefits regardless of team skill or MCU limits.

D Choose the newest language available to future-proof the project, even if the team lacks experience.

E Pick the language that a single influential developer prefers, regardless of team capability.

What did Prabho point out as the primary trade-off when implementing polymorphism-like abstractions in C using function pointers?

A It enables polymorphism in C but can introduce significant overhead, increasing program memory usage on constrained microcontrollers.

B It provides polymorphism with zero runtime or memory cost, identical to native OOP languages.

C It is inherently unsafe and guarantees system crashes in embedded environments.

D It completely eliminates the need to maintain or update drivers across different projects.

E It automatically converts C code into C++ and thus requires a C++ toolchain.
