OSM Size M SiP Integrates STM32MP1 MPU for industrial & IoT applications

ARIES Embedded MSMP1 OSM-compatible system-in-package (SiP) based on STM32MP1 CortexA7/M4 microcontroller for Industrial and IoT applications follows the company’s MSRZG2UL and MSRZFive OSM-compatible SiPs with Renesas Arm or RISC-V microprocessor introduced a few months ago. But instead of coming in the ultra-compact 30×30 mm OSM Size S form factor, the new MSMP1 complies with the larger 45x30mm OSM Size M form factor with a total of 476 contacts to allow for more I/Os. The SiP also integrates 512 MB to 4 GB DDR3L RAM, and 4 to 64 GB eMMC flash. MSMP1 SIP specifications: SoC – STMicro STM32MP1 single or dual-core Arm Cortex-A7 processor up to 800MHz, with Arm Cortex-M4 real-time core up to 209MHz, Vivante GPU compatible with OpenGL ES 2.0 System Memory – 512MB – 4GB DDR3L RAM Storage – 4GB – 64GB eMMC NAND Flash 476-contact LGA with Networking – Gigabit Ethernet USB – USB 2.0 Host/OTG […]

Flashchip FCM32 is yet another alternative to STM32 microcontroller

Flashchip Microelectronics FCM32 development board

Once upon a time, people tried to avoid STM32 fakes and clones, but in a world where companies are allegedly purchasing washing machines to extract a few unavailable components, people have started to look for alternatives, and last week I wrote about the Geehy APM32 family of STM32 clones. But I had never heard about Flashchip Microelectronics FCM32 microcontrollers, and they are not that easy to find in search engines, so they must be relatively new. The company appears to make both FCM32F clones and FCM32H derivatives with no direct equivalent STM32 part numbers, a higher clock frequency, and faster flash. For example, the FCMF030F4P6 will match the specifications of STMF030F4P6 as far as I can tell. The good news is that the datasheet is available in both Chinese and English. The FCM32H030C8T6 appears to be a higher performance version of STM32F030C8T8 / FCM32F030C8T8 with a 100 MHz frequency, and […]

Geehy APM32F103 clone of STM32F103 MCU has been tested to work without PCB or code modifications

Geehy APM32F103 is a clone of STMicro STM32F103 MCU that has been tested by at least one person who claims it was just a drop-in replacement and PCB, code, hex, testing, and production did not have to be changed at all. Most STM32 microcontrollers are in short supply with 52+ weeks lead times and prices going through the roof, so people may be looking into the long list STM32 clones and fakes including APM32F103. They all claim to be pin-to-pin and firmware compatible, but when theory meets reality, things may go wrong. For instance, last year I had a conversation with one person who switched to GD32 microcontroller and had all sorts of issues (translated from French): I ordered samples from the GD32F103RCT6 (LQFP64) “clone”, tested them, and it’s a catastrophe… Out of 6 chips, I only managed to flash one. And that one will not boot either. I’ve dived […]

CherryUSB – A lightweight USB device/host stack for embedded systems

CherryUSB USB stack for embedded systems

CherryUSB is a lightweight open-source USB device/host stack for embedded systems with one or more USB interfaces. The stack implements various class drivers such as CDC, HID, MSC, audio, video, and so on. It’s apparently part of Boufallo Lab SDK (e.g. for BL702 MCU), and has been ported and tested with WCH CH32V307 RISC-V MCU, STMicro STM32F4, and Nuvoton NUC442 Cortex-M4 microcontroller, as well as a two Arm Cortex-M3 microcontrollers I’ve never heard of: EastSoft ES32F3 and MindMotion MM32L3xx. CherryUSB device stack highlights: Support for USB2.0 full and high speed Endpoint irq callback USB classes support Composite Device Communication Device Class (CDC) Human Interface Device (HID) including “Custom HID” Mass Storage Class (MSC) USB VIDEO Class (UVC1.0,UVC1.5) USB AUDIO Class (UAC1.0, UAC2.0) Device Firmware Upgrade CLASS (DFU) MIDI CLASS (MIDI) Test and Measurement CLASS (TMC) Vendor class Remote NDIS (RNDIS) support Support WINUSB 1.0,WINUSB 2.0 with BOS (Binary Device Object […]

FOMO (Faster Objects, More Objects) enables real-time object detection on low-end embedded systems

FOMO used to stand for “Fear Of Missing Out” in my corner of the Internet, but Edge Impulse’s FOMO is completely different, as the “Faster Object, More Objects” model is designed to lower the footprint and improve the performance of object detection on resource-constrained embedded systems. The company says FOMO is 30x faster than MobileNet SSD and works on systems with less than 200K of RAM available. Edge Impulse explains the FOMO model provides a variant between basic image classification (e.g. is there a face in the image?) and more complex object detection (how many faces are in the image, if any, and where and what size are they?). That’s basically a simplified version of object detection where we’ll know the position of the objects in the image, but not their sizes. So instead of seeing the usual bounding box while the model is running, the face position will be […]

Arduino releases secure bootloader based on MCUboot

Arduino has released a new bootloader based on MCUBoot to increase the range of features and firmware safety of Arduino products, with the first release targetting STM32H7 based Arduino Portenta and Nicla Vision boards from the Arduino Pro family. The release focuses on Arduino Mbed OS-based boards, but MCUboot is OS agnostic, and should also work with Zephyr, Nuttx, and Apache mynewt. The company has also made sure that the transition is easy and reused the existing OTA firmware upgrade process in place on Arduino boards. MCUboot Arduino highlights: Signed and encrypted updates – MCUboot has support for encrypting/decrypting images on-the-fly while upgrading. It will also check if the computed signature is matching the one embedded in the image before booting a sketch. Confirm or revert updates – After an update, the new Sketch can update the content of the flash at runtime to mark itself as OK. If everything […]
