I see the same issue with EWB 7.30. If there's something present in flash, IAR will erase the sections and flash the softdevice. In this scenario, I see errors sometime, and have to restart the session. Haven't seen a workaround yet, but I recommend checking out their latest EWB version to see if it has improved. Also try to update your Segger drivers to the latest.

Thank you so much. The only problem now is that I have to download and debug twice after erasing it for it to work. On the first download, I get " Warning: Stack pointer is setup to incorrect alignment. Stack addr = 0xFFFFFFFF" and it does not run properly. After downloading again, it makes it to main and runs the code no problem. Any solution for this?

Hi John,

Yes, it is possible to load the softdevice directly from IAR. First, I would recommend that you start off with a "nrfjprog -e" to ensure that your device is blank.

If you go to your IAR project settings

Options.. -> Debugger

Then select the "Images" tab, you have the option to download an extra image when entering debug mode.

You check this option and browse to the selected softdevice .hex location.

Now, when you enter debug mode from IAR, it will load the softdevice .hex as well.

Cheers, Håkon
