Dongshan Nezha STU devkit features Allwinner D1 RISC-V SoM/SBC

Dongshan Nezha STU is a development kit comprised of an Allwinner D1 RISC-V system-on-module (SoM) and a carrier board with three 40-pin headers to access I/Os from the RISC-V processor. While not quite as compact as the Sipeed LicheeRV module, the “Dongshan Nezha STU Core” module also doubles as a standalone single board computer (SBC) with USB-C, Ethernet and HDMI ports, plus a MicroSD card socket for the firmware, which reminds me of the Khadas Edge design. Dongshan Nezha STU specifications: Nezha STU Core SoM SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 512MB DDR3 memory (option up to 2GB – TBC) Storage – MicroSD card slot, 2Gbit serial NAND flash (MX35LF1GE4AB); Note the SPI NAND flash (U12) is not populated in the photo below.

Fixing performance issues with Realtek RTL8156B 2.5GbE USB dongle in Ubuntu

A few days ago, I reviewed a USB 3.0 to 2.5 Gbps Ethernet adapter based on Realtek RTL8156B chip in Ubuntu 20.04, and let’s say the reliability and performance were underwhelming. I got some recommendations like changing cables, the MTU size, etc… Playing around with cables did no help, but one comment mentioned the cdc_ncm driver could be the issue, followed by another saying that updating to Linux kernel 5.14 should install the correct r8152 driver… So I just did that:

sudo apt install linux-oem-20.04d

1	sudo apt install linux-oem-20.04d

This upgraded Linux 5.13 (shipped with Ubuntu 20.04 + HWE) to Linux 5.14, but still no luck as the system kept using the cdc_ncm driver with a half-duplex link:

jaufranc@cnx-laptop-4:~$ inxi -n

But then I thought I may have to use udev rules to prevent loading the cdc_ncm driver, and there’s indeed 50-usb-realtek-net.rules in r8152 driver to do just that. So I copied the file in /etc/udev/rules.d/ folder. Since I […]

RISC-V or Arm? This tiny 4x4cm Linux board with WiFi offers both options

Last fall, we wrote about Allwinner D1s/F133-A RISC-V processor and the upcoming MangoPi MQ1, a tiny 4x4cm board based on the processor. The board is not for sale, but we have more details, and the company is also working on an Arm version equipped with Allwinner T113-S3 dual-core Cortex-A7 processor that is pin-to-pin compatible with F133-A SoC. The Allwinner F133-A board will finally be called MangoPi Nezha-MQ, or MangoPi MQ for shorts, and come with 64MB on-chip RAM while the Allwinner T113-S3 board, with 128MB on-chip RAM, will be named MangoPi MQ-Dual. Both are fitted with a Realtek RTL8189-based Wi-Fi module, offer display and camera interfaces, two USB-C interfaces, and headers for GPIOs. MangoPi MQ RISC-V or Arm Linux board MangoPi MQ/MQ-Dual specifications: SoC (one or the other) MangoPi MQ – Allwinner D1s/F133-A 64-bit RISC-V processor @ 1 GHz with 64 MB DDR2 MangoPi MQ-Dual – Allwinner T113-S3 32-bit dual-core […]

Allwinner T113-S3 dual-core Cortex-A7 SoC features 128MB DDR3, targets automotive and industrial applications

Allwinner T113-S3 is a dual-core Cortex-A7 processor with 128MB DDR3 on-chip memory that is designed for smart control and HMI applications in the automotive and industrial sectors. At first glance, the new processor looks quite similar to Allwinner S3, but with twice the number of cores. However there’s more to it, as a a HiFi4 DSP has been added for smart audio applications, the H.264 encoder is gone replaced by an MPJEG encoder, and the company claims support for “industrial level working temperature”, plus a 10-year life cycle. among other differences. Allwinner T113-S3 specifications: CPU – Dual-core Arm Cortex-A7 with 32 KB L1 I-cache + 32 KB L1 D-cache per core, and 256 KB L2 cache DSP – Single-core HiFi4 Memory – 128 MB DDR3 Storage I/F – SD3.0/eMMC 5.0, SPI Nor/NAND Flash Video Decoding – H.264, H.265, MPEG-1/2/4, (M)JPEG, VC1 up to 1080p60 Encoding – JPEG/MJPEG up to 1080p60 […]
