Google Pigweed Libraries Streamline Embedded Software Development on 32-bit Microcontrollers

There are many components required for embedded software development, including cross-toolchain, a build system like buildroot or YoCto Project, and debugging tools like OpenOCD. Once you’ve installed those, development involving several steps including building the code, flashing it to the board, and then running the program on the target. Google would like to make embedded software development to be as easy as web development as possible, similar to editing a file and running it in a web browser, so they’ve just released Pigweed open-source collection of embedded-targeted libraries/modules to streamline the development process for 32-bit microcontrollers such as STMicro STM32L452 or Nordic Semi nRF52832. Pigweed aims to help all steps of the process including tools/environment setup, program development, and code submission. Setup consists of running a bootstrap script that will automatically install tools such as Python 3.8, clang-format, and an Arm compiler in a virtual environment in order to leave […]

Octavo Systems Announces Development Boards based on OSD32MP1 System-in-Package (SiP)

Announced in February 2019, STM32MP1 Cortex-A7/M4 processor family recently got an update with 24 new SKU’s boosting the Cortex A7 core frequency to 800 MHz instead of just 650 MHz for the SoC’s announced last year. One of the first companies to take advantage of the new parts will be Octavo Sytems that unveiled OSD32MP1 system-in-package (SiP) last year combining STM32MP15x MPU, up to 1GB RAM, 4K EEPROM, STPMIC1 power management IC, two oscillators, and over 100 passive components into a single chip. The company also introduced two upcoming development kits for the STM32MP1 based SiP: OSD32MP1-BRK “Flexible Prototyping Platform” and the more featured OSD32MP1-RED evaluation & development board. Both boards are supported by OpenSTLinux which we covered in our previous articles about STM32MP1. OSD32MP1-BRK Breakout board for OSD32MP1 SiP The first board aims to provide easy access to the I/O of the STM32MP1 processor via breadboard compatible headers, and […]

STMicro Updates STM32MP1 Family with 800 MHz Cortex-A7 Processors

Until last year, all STM32 microcontrollers were based on Arm Cortex-M “MCU” cores, but that changed with the introduction of STM32MP1 Cortex-A7 + Cortex-M4 processor a year ago. That meant for the first time, we had an STM32 processor with an MMU capable of running Linux or Android. The company had three product lines: STM32MP157 – Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface and CAN FD STM32MP153 – Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz and CAN FD STM32MP151 – Single Cortex-A7 core @ 650 MHz, Cortex-M4 core @ 209 MHz All available in four different packages, and with or without hardware security (parts with A and C suffix) meaning we had a total of 24 parts. STMicro has now announced 24 more parts whose main and only difference compared to the STM32MP1 processors launched last year […]

STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. […]

MYIR Launches SoM & Development Board based on STM32MP1 Microprocessor

MYIR, the Chinese based company that has developed several ARM-based hardware solutions, has introduced a new SoM powered by the ST’s STM32MP1 microprocessor called the MYC-YA157C CPU Module with an accompanying development board known as the MYD-YA157C development board. Early last year, STMicro announced the introduction of the STM32MP1, the first STM32 MPU (Microprocessor Unit) that features one or two Arm Cortex-A7 cores running Linux, as well as an Arm Cortex-M4 real-time core making it possible to use previous STM32 codes on the new unit. Although, less than 1-year-old, the STM32MP1 microprocessor has since be deployed on a couple of development boards like the STMicro’s own discovery kits and evaluation platform, Emtrion emSBC-Argon, PanGu single-board computer, and even octavo systems unveiled the OSD32MP15x system-in-package. One primary observation with these other developments boards is their relatively steep cost, and something MYIR aims to address. MYiR MYC-YA157C STM32MP1 CPU Module The MYC-YA157C […]
