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.

Allwinner H2 Linux & Android SDK, and Allwinner XR819 WiFi Driver Released

Orange Pi Zero is an interesting little ARM Linux board thanks to its low price, but also because it features a new Allwinner H2 / H2+ quad core Cortex A7 processor very similar to Allwinner H3 minus the 4K video decoding part, as well as Allwinner XR819 WiFi module, which I have not seen on any other boards so far. But hardware without software is pretty much useless, so developers will be happy to find out that Allwinner H2 SDK with Linux (lichee) and Android has been released or leaked, and it also includes the Allwinner XR819 WiFi driver. You’ll find the SDK on Zoobab server with three main directory / files: Android folder – Android 4.4.2 SDK lichee folder – Linux 3.4.39 source code. However you’d probably better use Linux 3.4.113 currently released by sunxi-linux, or Linux mainline. The latter does have some limitations, and may or may not […]

NXP Unveils MCUXpresso Development Tools for LPC and Kinetis Microcontrollers

After NXP bought Freescale, you had development tools for Freescale Kinetis MCUs such as Design Studio or Kenetis SDK, and others such as LPCXpresso for NXP LPC microcontrollers. The company has worked to unifying software and tools support between its ARM Cortex-M MCU families, and has now announced MCUXPresso software and tools for both NXP Kinetis and LPC MCUs. MCUXpresso unifies thousands of Kinetis and LPC microcontrollers under a set of compatible tools including MCUXpresso SDK – Open-source software MISRA-compliant development kit (SDK) with peripherals drivers, wireless & wired connectivity stacks, middleware, real-time OS, getting started guides, API documentation, and application examples. MCUXpresso IDE – Integrated development environment (IDE) for editing, compiling and debugging. It also integrates MCU-specific debugging views, code trace and profiling, multicore debugging, etc… Both free and professional edition of the IDE will be available, and LPCXpressor and previously Freescale Freedom & Tower platforms will be supported.
