In my experience Rust sucks if you have to do discovery or prototyping, this because you almost have to build the whole house of cards before it works. However, if you know exactly where you are going Rust is ok, I noticed that the earliest POC was in C then Rust came along, Also this is the 12 Volt non critical ECU so it seems there still is a bit of work to get to the mission critical stuff.

Hey guys, I could use some career advice!
I'm currently in my second year of university studying Electronics and Communication, and I’ve been working with Arduino and microcontrollers since I was 14. Over the years, I’ve learned quite a bit about Arduino, AVR, STM32, ESP32, custom board design, Embedded C, register-level programming, and some IoT as well.

Right now, I’m trying to figure out what to specialize in so I can land a good job in the next two years. I’d love to work in a big MNC within the electronics industry or possibly join my dad’s instrumentation manufacturing business—or even start my own hardware company down the line.

I feel like I’ve got a good foundation in generalized electronics, but I’m not sure which area I should focus on next, especially considering current trends. What fields do you guys think would be best for me to master, given my background? I also feel like my early start gives me an edge compared to my classmates (most of them haven't even touched an Arduino), so I want to make sure I’m leveraging that advantage.

Thanks in advance for any advice!

UUmesh Lokhande I think I got your point now

ZacckOsiemo•10/7/24, 1:27 PM

Basically In C, you can quickly prototype a motor control application by directly accessing registers and using global variables, even cutting corners for speed. In Rust, strict rules like ownership and borrowing force you to handle memory safety upfront, slowing down development during prototyping.

Hi @ZacckOsiemo, my last gig was in the Open Source Program Office at Cisco and have spent a lot of time over the years working on Kubernetes and Infrastructure/Platform automation.

I've always been interested in alternative computing architectures, microcontrollers, and fpgas, but never "had the time" to really explode. Now that I have a few months off, I'm planning on taking the time to dive in head first.

I'm currently furiously 3d printing some organizational needs for my office, then I'm planning on blogging, recording, and streaming my misadventures in hardware

Hi @Ming A friend of mine was wondering:
How do you approach a situation where a build doesn't work as expected due to variables changing, skipping, or being overridden by included meta-layers? The build is technically successful, but the outcome isn't what we anticipated. How can we debug this kind of behavior and effectively track variable values and overrides?

For a concrete example, consider an SoC vendor meta-layer with two different versions, such as community and proprietary. We aim to include only specific parts of the vendor's meta-layer, but it's interfering with the development kit BSP layers.

Ming•10/8/24, 9:24 AM

Without knowing the specific details, the approach I would take is:

First:, run
bitbake-layers show-layersbitbake-layers show-layers
This will show you all the layers you have defined and more importantly, their priorities.

The next thing would be to run
bitbake -e <recipe>bitbake -e <recipe>
Where <recipe><recipe> is the image or recipe you are interested in. This will show you all you variables along with how and where they are set. This can be a large output, so I normally pipe it to file
bitbake -e my-production-image > image-env.logbitbake -e my-production-image > image-env.log

Now you can start searching that file for the variables you are interested in.

One thing I have found is that the quality of layers from vendors is very.... 'variable'! I have been know to create an intermediate repository from a vendor layer and then manually cherry-pick the bits I actually want. It is a pain, you you now have to manually keep the layers up to date, but it can be less effort than tearing your hair out trying to work out how to work around the vendor.

Boss lady•10/9/24, 10:42 AM

Zephyr OS has become a popular choice for embedded systems due to its real-time performance, modular architecture, extensive hardware support, and built-in security features. Designed for time-sensitive applications such as industrial automation and medical devices, Zephyr ensures that tasks are executed predictably, meeting strict timing requirements.

I prefer it because of its modular design allowing developers to tailor the OS to fit specific project needs, keeping it lightweight and efficient for resource-constrained environments. Zephyr also supports a wide range of hardware architectures like ARM, RISC-V, and x86, offering flexibility for multi-platform projects. Through its use of the Hardware Abstraction Layer (HAL) and device trees, it simplifies hardware configuration without code changes.

Also it takes security as a core feature, with integrated support for secure boot, trusted execution environments, and memory protection, making it a strong option for IoT and connected devices. Zephyr also includes cryptographic libraries and network security features, ensuring safe communication over networks.

If you would like to know more about zephyr you can check out the Zephyr Project GitHub repository and the Zephyr documentation. You can also access the Zephyr OS PDF guide for a comprehensive overview of its capabilities.
