Upcoming Raspberry Pi Compute Module 4 possible release date

A new milestone of Industrial IoT might come to life in this year. The successor of Raspberry Pi Compute Module 3+, working named Compute Module 4, will certainly draw from Raspberry Pi 4 B features, such as new Cortex-A72 processor (Broadcom BCM2711) and multiple RAM/eMMC options. Rumours say, that we may also see Gigabit Ethernet and USB3.0/3.1 support, since it was a main drawback in previous models.

Upcoming Raspberry Pi Compute Module 4 possible release date
Raspberry Pi release timeline with probable Compute Module 4 release date

First Rasbperry Pi 1B model had it’s analogy in industrial Compute Module 1 after almost 2 years from it’s premiere. Compute Module 2 was probably omitted because the change from RPi1 to RPI2 mainly involved a minor change of the processor (Cortex-A7 900MHz), which was almost immediately replaced with Cortex-A53 1.2GHz in Raspberry Pi 3.

The premiere of Compute Module 3 occured a year after RPI 3 announcement, providing a significant boost of industrial market solutions. Since Raspberry Pi 4 was a great success in 2019, we might see it’s equivalent in industrial series of Raspberry Pi – Compute Module 4. A possible release date of Raspberry Pi’s Compute Module 4 is mid-2020.

Raspberry Pi is gaining recognition in Industry

Almost a year ago, in the beginning of 2019, Raspberry Pi Foundation presented Raspberry Pi Compute Module 3+, a successor to previous CM3 version of development board, aimed at businesses and industrial users. The Compute Module uses a standard DDR2 SODIMM (small outline dual in-line memory module) form factor. GPIO and other I/O functions are routed through the 200 pins on the board.

Only a few months later, in June 2019, came big premiere of Raspberry Pi 4 Model B, the long-awaited successor of customer RPi3+. With new processor, larger RAM options and many input/output changes, became new standard in small, embedded PC world.

It seems a matter of time before the Raspberry Pi Compute Module 3+ will get its own successor, probably called Compute Module 4, a new milestone of professional embedded IoT module. What might be the specification of this highly expected development board?

Raspberry Pi Compute Module 4 specification forecast

Compute Module 4 specifications probably will look like these:

  • Broadcom BCM2711, Quad core Cortex-A72 @ 1.5GHz will highly plausible replace previous Broadcom BCM2837B0, Cortex-A53 64-bit SoC @ 1.2GHz,
  • 1GB, 2GB or 4GB LPDDR4-3200 SDRAM will become a standard options, instead of fixed 1GB LPDDR2 SDRAM,
  • Current flash memory (eMMC) options: 8GB / 16GB / 32GB from CM3+ will probably stay the same,
  • H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode) might replace outdated H.264 (1080p30)
  • and OpenGL ES 3.0 graphics will replace 1.1, 2.0 versions,
  • weight and factor will stay the same, to provide a possibility to upgrade current IoT applications of CM3 and CM3+

A Lite 4 version of Compute Module is to be expected too, without eMMC and probably limited SDRAM options.

With much higher performance, the new Raspberry Pi Compute Module 4 will, for sure, support Gigabit Ethernet, USB 3.0 expansions. We might even see wider working temperature range, if Raspberry Pi Foundation decides to make some hardware changes, to follow, for example, ESP32 – used in end-point IoT automation.

ESP32-based LoRa / LoRaWAN wireless network

One way of long-range and low-power data transmission is LoRa wireless technology. Since the Internet of Things market (with ESP32 – based solutions) is mainly covered with short-range Wi-Fi and Bluetooth and long-range with 3G / NarrowBand-IoT technologies, LoRa oftens is omitted or simply unknown by IoT users. Below you will find a short representation of what LoRa is and how can it be used.

What is LoRa / LoRAWAN network?

LoRaWAN® network architecture is deployed in a star-of-stars topology in which gateways relay messages between end-devices and a central network server. The gateways are connected to the network server via standard IP connections and act as a transparent bridge, simply converting RF packets to IP packets and vice versa. The wireless communication takes advantage of the Long Range characteristics of the LoRa physical layer, allowing a single-hop link between the end-device and one or many gateways. All modes are capable of bi-directional communication, and there is support for multicast addressing groups to make efficient use of spectrum during tasks such as Firmware Over-The-Air (FOTA) upgrades or other mass distribution messages.

Linux Kernel 5.5 brings changes to ARM, RISC-V and MIPS

At the end of last week, Linus Torvalds brought a complete list of Linux 5.5 changes for ARM, MIPS and RISC-V architectures. Io_uring asynchronous I/O has been improved, adding the ability to modify the set of files being operated on without starting over, user-specifiable completion-ring sizes, absolute timeouts, and support for accept() calls among others.

Also the Airtime Queue Limits (AQL) for WiFi that make CoDel work more effectively with wireless drivers that utilized firmware/hardware offloading. KUnit unit testing framework for the Linux kernel with tests can now be run locally on a developer’s workstation without any VM or special hardware. Another change is SMB rootfs and multichannel support using SMB as root file systems, and support for using multiple network connections for the same SMB session.

For more information about changes to different architectures, check out the article exploring the subject: https://www.cnx-software.com/2020/01/27/linux-5-5-release-main-changes-arm-mips-and-risc-v-architectures/

Linux 5.5 changes announcement

So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.

Outside of those, it’s all really tiny, even if some of those tiny changes touched some core files.

So despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now.

That means that the merge window for 5.6 will open tomorrow, and I already have a couple of pull requests pending. The timing for this next merge window isn’t optimal for me – I have some travel and other things going on during the same two weeks, but hopefully it won’t be all that noticeable. But there might be random timezones, odd hours, and random delays because of that. I try to avoid scheduling things during the merge window, but hey, it doesn’t always work out, and I’d have to delay things by two weeks to avoid the conflicts, which just doesn’t seem worth it.

Particularly since it’s not necessarily going to be a problem to begin with. We’ll see.

Anyway. Go out and test 5.5, and start sending me those pull requests for all the new development that is ready,

New release of OpenWRT 19.07 for WLAN devices

Good news for developers and modders of router software. A new Linux distribution, OpenWRT 19.07 has just been released, created primarily for WLAN devices, which debuted with the iconic Linksys WRT54G routers. OpenWrt 19.07 is mainly developed for devices using the AVR32, ARM, CRIS, m68k, MIPS, PowerPC, SPARC, SuperH, Ubicom32, x86 and x86-64 architecture.

What’s new in OpenWrt 19.07

A lot changed from the previous version of OpenWrt 18.06 version. Even WPA3 support has been added. However, it is not enabled by default and requires the installation of additional packages. Hostapd-openssl is needed for WPA3 to work in access point mode, it will need wpa-supplicant-openssl or wpad-openssl (additional AP) to use in Wi-Fi station mode.

Software developers have decided to switch to ath79 from ar71xx – in the future support for ar71xx will be completely withdrawn. In addition, the Linux kernel has been updated to version 4.14.162, and support for adm5120, adm8668, ar7, au1000, ixp4xx, mcs814x, omap24xx, ppc40x, ppc44x and xburst has been terminated.

A new feature is the updated LuCI, an integrated web interface for OpenWRT that implements client-side rendering. The LuCI ecosystem is large and not all LuCI applications have been adapted for this change, which can cause cbi.lua crashes. If so, install the luci-compat package.

The latest version of software can be downloaded from the project’s official website, here where you can also find the full list of changes.

Why should you try OpenWRT?

People who like to modify soft routers will confirm: OpenWRT dramatically increases the capabilities of network devices. OpenWRT is several thousand software packages that advanced users can install or remove depending on their needs. The software also improves network security – after all, the router owner will have full control over the configuration of every aspect of the hardware.

Industrial use of OpenWRT-based solutions

One of industrial IoT devices, supporting the technology and it’s varieties is ModBerry M series from TECHBASE. Economical, M300 model, based on NanoPi boards can serve as an OpenWRT modem, with optional changes in standard ModBerry controller.
