• [CM4] Best general way to handle a hardfault/lockup
    Over the past few months I've been doing a lot of work on a Kinetis K24 processor, which is a Cortex-M4, running the MQXLITE RTOS. It also has a couple other SDKs built in and a surprising level of complexity...
  • The easiest way to debug a lockup reset on Cortex M7
    In my Cortex M7 based project I am in a condition where often a reset takes place apparently for no reason. The only thing I can think of is that there has been a lockup. If I have a breakpoint at the...
  • JTAG to TrustZone Cortex-M33
    Hey evryone, I have a question in component security context. I program my MCU from a JTAG port. I also have a secure UART device in RX to display in hyper terminal. Can an attacker get access to...
  • Cortex M33 Tracing
    Hey, As I am exploring the tracing capabilities present in the Cortex M33, there are some things that I am not able to understand fully, such as the connection between ETM and the tracing sinks. As...
  • ARM Cortex-M33
    Highly versatile, the Cortex-M33 processor features configuration options including coprocessor interface, DSP, floating point computation with increased performance + efficiency relative to Cortex-M3...
