Raspberry Pi 4 no longer available with 1GB RAM

The Raspberry Pi platform, with introduced in 2019 Raspberry Pi 4 is no longer available with lowest, 1GB RAM configuration. Since the price of 2GB version dropped by $10 to the $35 — the same as the 1GB version. Therefore the 1GB is no longer available for puchase. Also the USB type C problems were fixed with the latest revision.

In latest announcement, Eben Upton, co-founder and CEO of Raspberry Pi Trading, admitted that most people already know that Raspberry Pi 4 requires at least 2 GB of RAM to be the first Pi to replace desktop computers. Upton also says, that comared to original original Raspberry Pi, the new RPI 4 has 40x processor performance, 10x bandwidth and 4x screen pixels. The SBC also has 4 to 8 times more RAM than the previous 512 MB model.

Raspberry Pi increase in IoT significance

More and more engineers and technology providers believe that it is suitable for industrial applications in the real world. Over the past few years, there has been a lot of discussion about the use of Raspberry Pi in industry, most of which emphasize that Raspberry Pi is a great tool for engineering experiments, but not so much for industrial applications in the real world. While it is true that the Raspberry Pi is not considered the best choice for mission-critical applications, it is also true that the Raspberry Pi is no longer a platform for experimentation.

Latest Raspberry Pi 4 development board, equipped with a 1.5GHz quad-core 64-bit ARM Cortex-A72 processor (approximately 3 times better performance than previous Cortex-A53 powering Raspberry Pi 3+ Model B and Compute Module 3 and 3+). can be chosen from 1GB / 2GB / 4GB LPDDR4 SDRAM options.

Raspberry Pi 4 continues the tradition of one of the most versatile and cheapest computer devices. It can be used for virtually anything from proprietary IoT solutions to a full-fledged desktop computer. The new Malinka has two micro-HDMI ports, a Gigabit Ethernet port, two USB 3.0 type A ports and two USB 2.0 type A ports.

Industrial use of Raspberry Pi 4

A year ago, TECHBASE released an updated version of the ModBerry M500 industrial IoT computer, replacing the aging Raspberry Pi 3 with a 3B+, giving it better performance. With the recent launch of the Raspberry Pi 4, TECHBASE has yet again, announced another upgrade to the M500, which now packs the latest single-board computer.

Over 10 million Raspberry Pi’s have been sold and the Raspberry Pi is likely to stay as a new standard in the industry. Official Raspbian OS is free operating system based on Linux Debian optimized for the Raspberry Pi comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation. ModBerry devices are compatible with Raspberry Pi accessories, supported by Raspberry Pi Foundation. ModBerry M500 now with Raspberry Pi 3 Model B+ / Raspberry Pi 4 Model B support.

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.

Raspberry Pi Compute Module 3+
Raspberry Pi Compute Module 3+

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.

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,
