Segger embedded studio debugger never hits breakpoint plus#

With this plus RTT most things you can attempt debugging on the fly without disrupting the softdevice operations. It's another great tool to have in your tool belt.

Segger embedded studio debugger never hits breakpoint code#

I also confused myself a bit because code was running while I was stopped and so you had to be aware that 'current state' wasn't necessarily quite what you thought. I did find that if I single stepped over code constantly, eventually it would break in the softdevice in a similar way to normal debugging, so I'd say it stays 99% out of the way of the softdevice but if you hammer at it, you'll probably break in the end. I found it was great for breaking, looking at the state of things, then letting the code run on for a while and doing the same again. It's 2 orders of magnitude better than normal debugging even though it's not 100% absolutely perfect.

Production programming guide (how to program 100 all the way to over 1,000,000 nRF5x devices in production).

Designing custom PCBs for an optimal development experience.

Bench marking code size and Coremark on nRF51 & nRF52 with the armcc, IAR, GCC and LLVM compilers.

What would you like to see? Some planned posts include: More blog posts on the Toolchain are coming your way. about getting it working in Keil, IAR as well as SES. This will have a chapter on MMD with info.

Go to the most recent J-Link Software & Documentation pack "C:\Program Files (x86)\SEGGER\JLink_V510h" and see J-Link User Guide in the Manuals folder.

You can find more info about monitor mode debugging in your SEGGER folder.

A tutorial on using MMD with a BLE application is planned and in the works. Please let us know in the comments and how you would like to use it. We would like to know what you think about monitor mode debugging. A different JLINK_MONITOR_ISR_xxx.s file is needed for Keil and IAR. Monitor Mode Debugging is supported in SEGGER Embedded Studio, Keil uVision and IAR.

At the top of main.c add ' NVIC_SetPriority(DebugMonitor_IRQn, 3ul) ' to be the lowest priority possible (3 on nRF51, 7 on nRF52).

In project properties under "Debugger -> J-Link Options" enter the command 'SetMonModeDebug = 1' in the "Execute J-Link Commands on Connect." This tells the J-Link FW running on the development kit MMD will be used.

Make sure 'DebugMon_Handler' system interrupt is defined in your startup file after 'SVC_HANDLER.'.

Add the monitor mode debug files to your project (JLINK_MONITOR_ISR_SES.s, JLINK_MONITOR.c,h).

Press Button 1 and LED1 will still be toggled! Or set a break point in the while loop and notice the LED still toggles. At the top of main.c you may have to change the pins the led & button are assigned to based on the board you are using. Press Button 1 and LED1 will toggle on your board. Now under the "Build" tab at the top of the screen select "Build and Debug." Or you can just press the green play button "Start." This is what your project should look like. For this project to compile the paths 'components\toolchain\gcc,' 'components\toolchain,' and 'components\drivers_nrf\hal' will need to be included in your project. Click "User Include Directories" and change these absolute paths to be correct for your system.

Right click "Project 'Generic_Cortex_M'." This will open a window that allows you to edit the project properties and also shows the most common project properties that will need to be modified.

Only some very slight modifications are needed to run this example.

If you haven't already installed SES please look at the blog linked in the beginning of this post and follow the simple instructions to get it up and running.ĭownload this zip file, extract it, and open the SES project file. There are many use cases, but at least most of us have experienced losing BLE connections while debugging and ending up in a hardfault/error handler when we continue code execution. Some use cases of this are: a BLE application can maintain its connection, a PWM can continue to operate a motor, a sensor can be read and its interrupt cleared so it can continue collecting data, etc. MMD allows you to halt the CPU while debugging (breakpoints, pausing execution) but still service interrupts with priority. In this post we will explore SES more and experiment with Monitor Mode Debugging (MMD). Please at least skim through that post if you haven't already. In the last blog post we introduced you to SEGGER Embedded Studio (SES).

Segger embedded studio debugger never hits breakpoint series#

It will not work with nRF51 series devices as Cortex-M0 doesn't support this feature. Monitor mode debugging can only be done on nRF52 series devices. Never lose a BLE connection when debugging your applications again! This technique will also be useful for any application using the PWM peripheral and many others as well! This tutorial will take less than 15 minutes.
