BeagleBoard.orgin tunnettu PocketBeagle-kehittäjäkortti on saanut merkittävän päivityksen uudessa PocketBeagle 2 -versiossa. Uudistuksessa laitteeseen on lisätty neliytiminen suoritin ja ensimmäistä kertaa myös grafiikkaprosessori, mikä avaa entistä laajempia mahdollisuuksia sulautettujen järjestelmien kehittämiseen.

Alkuperäinen PocketBeagle 2 perustui Texas Instrumentsin AM6232-piiriin, jossa oli kaksi 64-bittistä Arm Cortex-A53 -ydintä. Nyt laitteesta julkaistun Rev A1 -version myötä piiriksi on vaihdettu AM6254, joka tuo mukanaan neljä Cortex-A53 -ydintä jopa 1,4 GHz kellotaajuudella sekä integroidun 3D-grafiikkaprosessorin. Muistin määrä (512 Mt LPDDR4) säilyy entisellään.

Beagleboard has recently announced the PocketBeagle 2, a single board computer (SBC) built around TI’s AM6232 dual-core Cortex-A53 and Cortex-M7 SoC and an additional MSPM0L1105 Arm Cortex-M0+ microcontroller for ADC pins and board ID storage. Designed for developers, students, and hobbyists, it’s a direct upgrade from the previous generation PocketBeagle which the company released in 2017. The new board comes with a faster dual-core 64-bit CPU (compared to a single-core CPU), faster memory (DDR4), improved power management (USB-C + LiPo charger), and easier debugging (UART + JTAG) for faster development.

Developers can now rapidly prototype with the OSD3358 System-in-Package (SiP) using BeagleBoard.org® PocketBeagle® and MikroElektronika click boards™. This blog will describe the procedure for interfacing a new click board™ with PocketBeagle® using the OLED-C click board™ as an example

[Ken Shirriff] is no stranger to the pages of Hackaday. His blog posts are always interesting, and the recent one talking about the PocketBeagle is no exception. If you are old enough to remember the days when a Unix workstation set you back tens of thousands of dollars, you won’t be able to help yourself marveling at a Linux computer with 45 I/O pins, 8 analog inputs, 512M of RAM, and a 1 GHz clock, that fits in your pocket and costs $25. What’s more the board’s CPU has two 200 MHz auxiliary CPUs onboard to handle I/O without having to worry about Linux overhead.

[Ken] shows a small snippet of C code that outputs a 40 MHz square wave no matter what the Linux OS is doing. In this way you can use Linux for the parts of your application that are not that critical, and use the slave processors to handle real time processing.
