segger embedded studio data breakpoints expressions nRF52833

[Learner]

Hello,

I am trying to set a data breakpoint expression on a global array or global variable  but I don't seem to be able to.

Each time I set a data breakpoint I get a '?' next to the breakpoint. See attached picture.

uint8_t ble_ad[HB_BLE_AD_BUFF_SIZE_MAX].

I am using segger Embedded Studio v5.60 and nRF52833 SoC.

Thank you.

Kind regards

Hi Vidar,

Do I need to download the Segger Ozone debugger app or is it already included in nRF Connect tools?

Where can I download it from and any getting started guide would be appreciated?

It looks like Segger Ozone is built into SES NE. I have found in SES NE under

Debug -> Debug With Ozone

But when I selected it nothing happened.

Kind regards

Mohamed

Hi Mohamed,

Ozone must be downloaded and installed separately. You should be able to open it via SES once installed.

Hi Vidar,

I downloaded Ozone and got it running but I still cannot set a data breakpoint with a C-like expression. See screen capture below. The OK field remains always greyed out and the only option available is 'Cancel'. What am I doing wrong?

Kind regards

Hi Mohammed,

In Ozone, the value condition is specified at the end and not as a part of the expression. Please try to do it like this:

Also, notice that the value mask is set to '0'. '1's in the mask are used to mark bits to ignore. 

Kind regards,

Great! it works now Thank you. The moral is "Read the user manual" 

I am chasing an intermittent bug which could be caused by a possible stack overflow. How do I set a data breakpoint that is triggered when ble_[6] != 0x19?

One more question. how do I capture the debugging logs appearing in the Terminal window in a text file automatically?

Kind regards
