March 13, 2017 -eSOL, a leading developer of real-time embedded software solutions, today announced that the eT-Kernel real-time operating system (RTOS) now supports the latest ARM®v8-M architecture for the ARM® Cortex®-M family. This includes support for the new ARM TrustZone ...
I would like to debug the Cortex-M33 based target device using J-LINK/J-Trace. However, µVision IDE does not offer me to select the J-LINK/J-Trace debug adapters for this architecture. Is it possible to debug this architecture-based devices using J-LINK/J-TRACE?
The Armv8-M Architecture allows up to 256 memory regions, but no implementation currently utilizes more that 16 regions. The configuration used in this tutorial supports up to eight regions. To confirm how many memory regions are in your M-profile device, software can read the MPU Type Registe...
