[ncs 3.2.0/3.2.1] Impossible to debug since ncs 3.2.0

[longo92]

Hi,

starting from ncs 3.2.0 (also in 3.2.1) when i attached the debugger (jlink ultra+, under VS code with nrf connect extension) to my nrf52833 board, i am getting the following error on RTT (on ncs 3.1.1 do not have such problem):
[00:04:29.238,311] <err> os: ***** BUS FAULT *****

Do you have the same issue if you try to connect with a debugger not with VS code? 

Have you tried to update the Jlink driver? 

I have not tried to reproduce this as of now.

i am on j-link v8.76.

I have tried only using VS code.

Maybe is an issue on my setup.

I will try with another board.

Are you using a sample when you try to debug? Or you own custom project. Have you changed some of the compile settings?

I am on custom project.

Effecively on simple led blinky sample on nrf54l15dk under ncs 3.2.1 i am not getting the issue.

I should try to debug using the nrf54l15dk as debug probe.

By the way:

1. Is it possible that i need to udpate my seggere jlink uktra+ firmware?It seems outdated (2022)...
2. Which version should i use with ncs 3.2.1? I am using the v8.76

Thanks,

Again

Hi Alessandro,
You can try and update but I am not convinced that is the issues as things work fine on previous version. Have you tested with the nRF53L15DK as the debugguer? If this works with no issues then I think its likley an outdated verison for the Jlink ultra.
