Propose a board we should consider

[mrinalwadhwa]

What host boards should Ockam be tested for?

[hollyfeld]

With the shear amount of hardware available, it seems like it might be easier to pick a few potential reference applications that vary in spec and then find hardware that fits.

• Sensor network
• Home IoT control panel / accessories
• Higher power commerical field device or wearable

Maybe you are looking for what community members are actively using? If that is the case, for me it would be AVR, STM32, and Linux/ARM SOM.

For my side, I am also using STM32,silicon labs and Linux SBC boards.

[mrinalwadhwa]

What boards the community is actively building with is exactly the kind of input I was hoping for. Thank you both. @hollyfeld @ranig-lab.

[Shwetha369]

Raspberry Pi since its a popular development board.

[mrinalwadhwa]

Thanks you @Shwetha369.
Our team does most our dev on Raspberry Pis and we're active testing against them ... plan is to have a some PIs be part of our automated build pipeline very soon.

On the more deeply embedded side (RTOS, bare-metal) I recommend the STM32 Nucleo or Discovery boards. They seem to be really common in the open source community.

Specifically, here is one variant that could be a good candidate: nucleo-f767zi. It has the connector for Arduino shields (e.g. sensor boards) and also has a on-board debugger, so no extra hardware needed for debugging.

[bbrown1867]

Slight correction to my original post - the nucleo-f756zg is probably a better candidate for this project since it has a crypto accelerator. Like @ranig-lab suggests, the H-series may be a good candidate as well assuming it has a crypto accelerator.

[mrinalwadhwa]

was trying to figure out the exact cryptographic capabilities of those nucleo series but so far no luck

Checkout section 2.37 and 2.38 of this document:

Looks like this micro supports symmetric encryption (AES, DES), hashing (SHA-1, SHA-2), and have an RNG. So the only missing feature would be asymmetric encryption, but that could be done in software using something like micro-ecc:

[ranig-lab]

Take a look in this website 🔢 http://www.emcu.eu/stm32-cryptographic-library/
It also describes the stm32 cryptographic library.

Thank you @bbrown1867 & @ranig-lab. That's very helpful.

@mrinalwadhwa , I've been building IOT applications with Digi XBee 3 SOCs. The advantages are low cost, built-in Zigbee Mesh networking, and a MicroPython programming environment. The downside is that it is low-powered and Python is the only language available.

Regards,
Cameron

[mrinalwadhwa]

@CameronMease thank you for that suggestion. I have no experience with MicroPython but I think making Ockam & MicroPython work together would be great!

It's on our roadmap to wrap our Rust code in Python to provide Ockam for Python devs.

RiscV Board getting more Industry Future Roadmap it is better Test RisCV Boards started with SIFIVE UNleashed boards for IOT applications .
