I solved my GCC problem by using just "symbol_file" to load symbols only to what was flashed by JLinkExe rather than using "file". Debugging no problem now! Yay!

As it turns out, there wasn't anything special I needed to do, no splitting required, although looks like I should have been using loadfile instead of loadbin to be totally correct, but that wasn't the problem either. My problem turned out to be that I don't have GCC working properly. Everything was working, I just couldn't tell because run under GCC, my program throws exceptions that it doesn't throw when not under GCC.

Awesome, thanks for the confirmation. Is there something special I should be doing to flash the s110 7.1.0? I'm doing something like this:

$ JLinkExe -device nrf51822 -if swd -speed 4000

J-Link> loadbin s110_nrf51822_7.1.0_softdevice.hex 0

I'm noticing old forum posts about having to split/convert the hex file into bin files. Is that necessary?

Thank you for the help!

It's supported - even tells you how to use the older boards with the 7.x kit. There's really nothing much different in there, the softdevice is the same, the 7.x kit is really mostly the same library code with the directory structure turned upside down. As long as the softdevice you're using matches the headers you're building with to call into it, you're fine.

There may come a point that Nordic takes advantage of the silicon bugs they fixed in the rev 3 hardware either in the softdevice code or the library code, but if that happens, and it's not happened yet, they'll make it very clear.

I can't suggest at all what your issue might be, but it's not a 7.1.0 hardware incompatibility issue.
