"We make things run smoothly."
These are some examples of projects we have done:
-
Linux/Bare-Metal Sample / Initialization for Texas Instruments Sitara™ AM6442
Design, implementation, and initialization of basic software on a Texas Instruments AM6442 microcontroller: 2 ARM Cortex-A53 cores with Yocto Linux, 4 ARM Cortex-R5F cores with bare-metal software for high-speed real-time operations. Boot from eMMC or Ethernet. Communication between all cores via shared memory. Devicetree and kernel module (driver) to access shared memory from Linux userspace program. Starting the R5F cores from Linux with debugging capabilities using Code Composer Studio (CCS).
Linux configuration, devicetree, kernel drivers, Linux application, bare-metal software
Keywords: Linux software (C++, GCC), Linux kernel module (C, GCC), bare metal, real-time, Sitara™, AM64x, ARM Cortex-A73, ARM Cortex-R5F, Code Composer Studio, MCU+ SDK, Processor SDK Linux
