I am trying to find the location of the register where the timestamp generator can be enabled on a Cortex-M4 processor.
In the CoreSight SoC Technical Reference Manual on page 3-210 it is mentioned that the register (CNTCR) is in the PSELCTRL region…
There's many references to Debugging a Hard Fault on Cortex-M3 & M4; eg

Hi everyone,
Apologies for asking a very similar question to those that are out there already, but this is my last hope as I have scoured Atmel and arm forums for a solution that works for me, but not found any yet,

As part of fault detection / debugging, it's useful to have a panic() function that halts the processor.
It is easy enough to disable interrupts and put the processor in an infinite busy loop (while (1)). However, that burns power, and I am looking…

Please, can anybody tell me, where I can download a prebuilt gcc and a prebuilt…
Hi,
I'm starting to explore this technology by running the TrustZone example application in Linux using GNU ARM Toolchain. This example is provided by a CMSIS software pack containing this example called "TrustZone for ARMv8-M No RTOS" which I was…
Why should we call secure function in handler mode? What is the design purpose for this? As we know, none-secure side can also call secure function in thread mode.
For the last weeks, I have been trying to get this new version to work. I did the same as with the previous version and now it is running on the Xilinx Nexys4. However, honestly I do not have any idea how to get the debugging to work. I defined the pins…
This blog is the second in a series on the new debug features in SOMNIUM DRT. The first one was about the live expression view.
Debugging is difficult, especially when unexpected errors cause the program to behave unpredictably, such as writing to an invalid…
