Panfrost now supports OpenGL ES 3.1 on Midgard (Mali T760 and newer) and Bifrost (Mali G31, G52, G76) GPUs

OpenGL ES 3.0 experimental support for Panfrost open-source Arm Mali GPU driver was announced in February 2020 and culminate with the release of Mesa 20.3 with Panfrost support last December. Collabora has now started to work on Panvk, Panfrost Vulkan driver, but that does not mean OpenGL ES work is done, and the company has just published a blog post about OpenGL ES 3.1 support in Panfrost. Alyssa Rosenzweig explains OpenGL ES 3.1 extends to both the older Midgard GPUs that include Mali T760 and newer version, and the more recent Bifrost GPUs with Mali-G31, Mali-G52 and Mali-G76. Compared to OpenGL ES 3.0, OpenGL ES 3.1 adds compute shaders, indirect draws, and no-attachment framebuffers. Boris Brezillon, Italo, Nicola, Alyssa, and the wider Mesa community especially focused on Mali-G52 GPU, found for instance in Amlogic A311D and Rockchip RK3566, with Panfrost driver passing essentially all of drawElements Quality Program and Khronos […]

RasPad 3 Review – Part 1: Raspberry Pi 4 “tablet” specs, unboxing and assembly

RasPad tablet kit for Raspberry Pi 3B+ and other SBC’s was introduced in 2018, but Sunfounder has recently introduced an update, RasPad 3 that supports the more powerful Raspberry Pi 4 SBC. After seeing my review of CrowPi2 Raspberry Pi 4 education laptop, the company asked me whether I’d be interested in reviewing Raspad 3 as well. So here we are, and I’ve received a sample of the tablet kit. As usual, I’ll do a two-part review, with unboxing and assembly of the kit. Since I previously missed the RasPad 3 announcement, I’ll start by listing some of the specifications. RasPad 3 specifications Compatible board – Raspberry Pi 4B with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8G RAM Storage – MicroSD card socket Display – 10.1-inch touchscreen IPS display with 1280×800 resolution, 10-point touch Video Output – Full-size HDMI output Audio – 3.5 mm headphone jack, stereo speaker Connectivity […]

Timesys Embedded Board Farm enables remote access to hardware for software development & QA

When you design a new board with an international team working in multiple locations, there may only be a couple of boards available for testing, and that’s mean some members of the team may not have access to the hardware. The same problem can be true for test farms with a larger number of boards. So it would be good to have a solution to remotely access and control the hardware to speed up development. A few years ago we wrote about MuxPi board using NanoPi NEO SBC to enable remote testing of development boards, but now Timesys has come up with a more advanced solution with the Embedded Board Farm (EBF) capable of sharing multiple boards across teams spread around the world. The solution is comprised of three main components besides the target boards: The Master Server integrated with LAVA test automation framework – It handles docker images, firmware/file […]

How much do you pay for cellular data plans?

I’m mostly working from home using a broadband “Fiber-to-the-home” monthly subscription, with a router handling the connection to computers and devices through Ethernet or WiFi. So I’ve very seldom used cellular data plans since I don’t exactly need to be connected each time I get out. But recently, I’ve been to places for around one or two weeks at a time without WiFi, and my ISP has gotten into the habit of disconnecting for several hours once a month, so I’ve started to connect to 4G cellular networks more often. So far I had purchased daily or weekly plans from my bank app depending on my need for under two dollars a day or $10 per week for a 10 Mbps “unlimited” connection. Unlimited here means the company will not throttle the connection to lower speed after reaching a cap. I had some problems with excessive packet loss (> 70%) […]

BastWAN Feather-compatible LoRaWAN board features RAK4260 Microchip R34 module

We’ve previously written about a Feather-compatible LoRaWAN board equipped with RAK4260 module based on Microchip R34 LoRa SIP called Penguino Feather. It appears somebody, namely Electronic Cats based in Mexico, decided to design an almost identical board with BastWAN. Let’s see if there are any differences besides the cheaper price. BastWAN specifications: LoRa module – Rak wireless RAK4260 module with: SiP – Microchip SAML21 Arm Cortex M0+ MCU @ 48 MHz, 32 KB RAM, 256 KB Flash, Semtech SX1276 LoRa Connectivity Frequency Range – 862 to 1020 MHz High level of accuracy and stability (32MHz TXCO) Max Tx Power: 20dBm; Max Sensitivity: -148dBm; Rx Current: 17mA (typical) Compliant with LoRaWan 1.0.2 Antenna – SMA and u.FL (IPEX) antenna connector I/Os – Feather headers with 20x IO pins including PWN, serial, I2C, SPI, 6x 12-bit ADC, 1x 10-bit DAC HW security – ATECC608A crypto authentication chip Programming and debugging 10-pin 4-pin […]

ClearFog CN9130 networking boards deliver 10GbE through a tiny Octeon TX2 module

SolidRun has designed and manufactured ClearFog networking boards ever since the introduction of the Marvell ARMADA 380/388-based ClearFog Pro in 2015. Since then, more powerful models have been launched including the ClearFog GT 8K based on Marvell ARMADA A8040 quad-core Cortex A72 processor with support for 2.5GbE and 10GbE, and the ClearFog CX LX2K equipped with a 16-core Cortex-A72 NXP capable of 100GbE networking. The Israeli company unveiled its first Octeon TX2-based design last fall with ClearFog CX CN9K, a full-featured networking SBC fitted with CEx7 CN9132 COM Express Type 7 module. But now the company has launched the more compact ClearFog CN9130 Pro/Base networking boards equipped with a tiny 50x30mm Octeon TX2 module still enabling 10GbE connectivity.
