Flashing .hex file through IAR with I-jet is not working.

Hi Team,

Regarding the IAR "I-jet" Debugger support for Nordic Platform (Nrf52840) we have observed some weird behavior.

1. When we connect the IAR I-jet Debugger we are able to debug and download the “.hex” files.
2. With the same code when we generate  ".hex” file and download through IAR with the “I-jet” debugger(“Project =>Download =>Download file”. it is not working, but if the same “.hex” file if we download/flash through other tools like “nRFConnect and Segger J-link” it is working fine.
3. With IAR I-jet we can debug only if we flash the code is not working, we have cross-checked with a couple of example projects as well. But the same Behaviour.

 Are there any other settings we need to look into for IAR point of view like any flash loader settings etc.. It should be very helpful to us if we can resolve this issue. If we need more info on this we will discuss on your free time.

 Regards,

Hi,

Please try to install the latest MDK for IAR and see if you get the same result. The installer is available for download from the product page here: https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-MDK/Download

With IAR I-jet we can debug only if we flash the code is not working, we have cross-checked with a couple of example projects as well. But the same Behaviour.

Can check the CPU registers and see where it gets stuck, or read out memory to see what's different compared to when use J-link?
