 So here we're checking out the Hope Run board here with the TI chipset. Hello, so who are you? Hey, I'm Mark Grossen. I'm an engineering manager with TI, and I work on the real-time operating system support at TI, which includes the Zephyr work being done here at Lunaro. And who are you? I'm Liu Yang from Hope Run. And right here, you have this board. It's available. How much it cost? $25. $25. So what is it for? Well, IoT, obviously. So it is a Cortex-M4 with an associated network processor that runs the whole Wi-Fi stack and TCP-IP stack and TLS. So the main MCU chip doesn't have to do any of the networking or security software. So it makes your M4 free for your whole application. And this is with Wi-Fi on the Cortex-M4? It's a separate Cortex-M that has the network stack and the Wi-Fi. So there are actually two Cortex-Ms on the device, one for your application and one just for the network. So it's kind of like an SoC? It is, absolutely. And it has a bunch of the usual peripherals, I2C, SPI, UARTs, A2D, camera interface, I2S, and those sort of things as well. And it runs Zephyr but some other real-time OS? Yep. TI, we have our own operating system called TI RTOS that has a TI kernel. And we also support free RTOS. Cool. How did you work on making this? And where are you based, the company? Yeah. You know what I said, our first 96 bots? Yeah. The first? Yes, our first 96 bots. And they were very exciting to work with TI on 96 bots. So did the TI and you work on the specifications, all the stuff that you'd like to have in there? Like, please have this, this, this, this. And you say, OK, no problem. No kind of problem. OK, no problem. You can just do it. Yeah. Yeah, and one of the nice things is working with Hope Run and 96 boards, we have a standard form factor. So with this connector, we can use all the mezzanine boards that are coming to do things like audio and sensors and all those things. So the form factor is very nice. It's usable both for, I think, development and also you could use it for an early product type demo system because it is so small and compact. And I think it even has a battery charger on it as well. So this is a JST for a LiPo battery? Yeah. OK. It's kind of like the same small battery as you have on the drone or something like that. You're just hanging on. Yeah, like a 1S cell. I will set the battery at LiPo. And the CC3220, is that a very massively deployed chipset out there in the world? Yeah, this is actually the second generation. There was a 3200. This is a new version. So the first generation had a lot of usage. This now adds IPv6 support and new TLS cipher suite. So it's a more up-to-date networking support. But it's a Cortex-M4, 1 megabyte of flash, 256K ran running at 80 megahertz. Low power consumption? Very low power. You can run this for years off two AAA cells with the right duty cycle, obviously. With the right software? And the right software. That's right. So it's software and hardware. And in those sort of things, you wake up every 15 minutes, take a sample, and send it over Wi-Fi. If you were continuously connected, obviously it won't last as long. And the RTOS, the TI RTOS, is that open source? Yes, it's all open source. It's BSD licensed. And like I said, it has a kernel. We have POSIX APIs for P-threads and BSD sockets. So it's very compatible with people who are used to the Linux environment. So it's easy to move your code back and forth. And we also support the popular open source FreeRTOS kernel as well. So you can choose either kernel, TI's kernel, or FreeRTOS. And then of course, working here with Alnaro, we'll have Zephyr support as well. So how does Zephyr compare with the TI RTOS? Well, it's a lot newer. It's different that way. It's also an industry cross ISA effort. So it's started by Intel. So it supports x86, ARM, MIPS, a couple other ISAs. So it's more like a Linux thing where it's vendor-independent and ISA-independent. Whereas the kernel that we have is only running on TI ISAs, like ARM and DSP and microcontrollers. You can't modify it to run it on another chip. You could. You could. We don't support it that way. But it is BSD licensed. So you could take it and run it wherever you wanted to. And do people submit a whole bunch of improvements to it all the time? We get improvements via our support forms. We have a very active support form so people either find bugs or ask for new feature requests. And then we implement them. We don't typically get source code patches. We get a few, but it's run more as a project that TI maintains and supports. So what can developers do with this? What do you think they will do with this? Zephyr? What kind of products maybe will happen? Maybe like some IoT devices like the smart store. Smart solution? Smart door? Yes, smart door. And maybe other IoT devices like the work. Many different. Yeah, many different. What do people do with this kind of chip set? There's a million different ideas? Yeah, the example of ELOX is one. It's very popular with video doorbells today. There are large customers using it for doorbells, as well as locks. In the industrial and automotive space, or more of the industrial space that's used for a lot of on-the-floor sensing type things, it has, since it has very good security, it's good in enterprise and industrial environments as well. So it has very good security? Yeah, it's got all the latest TLS and Cypher suites that are recommended for people to use. Opti? Opti, no. So this is a Cortex-M device, and so it's V7M, not V8M. So the next generation, which will be based on the new Cortex-M33, will have TrustZone-M. But those devices don't exist yet. All right, so right there, interesting 96-board product, and with support, with availability, and you're selling. We are selling this next month. You can buy it from internet. OK, cool.
