Getting Started with Pine64 PADI IoT Stamp – Part 2: Serial Console, GCC SDK, Flashing & Debugging Code

PADI IoT Stamp module powered by Realtek RTL8710AF ARM Cortex M3 WiFi SoC is a potential competitor to Espressif ESP8266 modules. Pine64, the manufacturer of the module, sent me their kit with a $2 IoT stamp, a breakout board, a USB to TTL debug board and a J-Link debug board. In the first part of the review I’ve shown the hardware and how to assemble PADI IoT stamp kit. In the second part I’m going to write a tutorial / getting start guide showing how to control the board with AT commands, build the firmware with GCC SDK, and finally demonstrate how to flash and debug the firmware with the J-Link debugger. The Quick Start Guide indicates you need to connect the USB to TTL debug board to UART2 instead of UART1 as I did on the very similar B&T RTL-00 RTL8710AF module, and set connection settings to 38400 8N1.

Make-WiFi-Fast Project Massively Improves WiFi Performance of Busy WiFi Routers

WiFi is a great way to add connectivity to a large group of people, but once everybody tries to connect at the same time, the network often becomes unusable due to very high latency, a problem that can occur on servers on the ISP side too, and that’s usually caused by excessive buffering, Bufferbloat. The Bufferbloat project aims to resolve this issue with both routers using CoDel and fq_codel algorithms, as well as WiFi via Make-WiFi-Fast project. Dave Täht gave a presentation of his work on Make-WiFi-Fast project entitled “Fixing WiFi Latency… Finally“showing how latency was reduced from seconds to milliseconds. It’s quite technical, but two slides of the presentation clearly shows the progress made. The first chart shows 100 stations connecting to a website using unpatched code with the top of the chart showing the bandwidth per node in MBits/s, while the lower part showing latency in ms. We […]

Banana Pi M2 Ultra Allwinner R40 Development Board with SATA & GbE Sells for $46

Allwinner A10 and A20 processors have been quite popular in the past since they could handle Fast or Gigabit Ethernet and SATA natively, included decent multimedia capabilities, and were found in low-cost hardware such as Cubieboard 2 or MeLE A1000. Since then we’ve had a few boards with SATA using newer and faster processors without SATA IP, meaning it was usually implemented using a USB 2.0 to SATA bridge leading to mediocre to average performance depending on the implementation and selected bridge. Allwinner R40 is the successor of Allwinner R20 with a faster quad-core Cortex A7 processor, but keeping Gigabit Ethernet, SATA, and most features of its predecessor. The good news is that Banana Pi has now launched the promised M2 Ultra development board based on the new processor for $45.80 + shipping on Aliexpress (Total for me: $48.35). Banana Pi M2 Ultra specifications: SoC – Allwinner R40 quad-core ARM […]
