Having trouble flashing from Eclipse

Which GDB launcher are you using? I had this trouble until I switched from DSF to the standard launcher.

Have you seen this? I suspect you may be seeing consequences of the same problem.

Also, are your project using a softdevice or not? If it is not, you should make sure that you don't in any way accidentially flash a softdevice to your chip, as that will most likely cause the kind of verification errors you see.

Personally, I find myself using command-line gdb more than Eclipse, and I've put my Makefiles and linker scripts on GitHub here. It might be a good idea to check whether things are working from the command line before moving into Eclipse, as I sometimes suspect Eclipse of causing additional problems...

no I just used the normal CDT plugin, the one nan-29 recommends. It's a bit of a bear, especially if you don't know eclipse (I don't .. well I didn't) but it works. I think nan-29 is ok, it got me started at least even making allowances for it being windows and me using OSX.

That plugin looks quite cute, I'll grab a fresh install of Eclipse and see if, now I've learned how eclipse works, that makes it any easier. If I'm feeling super smart I'll try building a template for nordic .. that won't be this week!

Sometimes I wish I didn't have a day job ..

Thanks. I probably found the same Eclipse plugin you did:

That's got me further along but I still haven't flashed the device using it, so I may hit the same issue you're seeing shortly. The plugin looks promising though - if it works then the Nordic NAN 29 should probably be updated to use it. I certainly never got far with the NAN 29 instructions as they are now.

It's not under current Toolchain, that should be set to 'Cross GCC' (if you don't have a Cross GCC option in the dropdown then you probably need to download another piece of the CDT in addition to those suggested by nan-29, I certainly added a few extra bits I thought would be useful).

Then in the option above that one, Properties -> C/C++ build-> Settings, in the first tab, 'Tool Settings', in the first option, 'Cross Settings' (man Eclipse has a lot of settings) there are boxes for prefix and Path which I have set to

arm-none-eabi-

and

<my homedir + stuff>/gcc/gcc-arm-none-eabi-4_7-2013q3

I actually didn't have to do a lot of that, I started with a new C project and picked Cross GCC as the toolchain right at the start and it asked me where things were. I didn't build this project around a working makefile, I started from scratch and set Eclipse up to have all the correct paths, includes and flags in it to build the way the makefile does. I'm hoping to turn that into some kind of template and then do another template for a project with softdevice, which I suspect is just going to be another 6 hours of mashing eclipse buttons until it works.

Afraid I can't help you with your flash issue but since you seem to have Eclipse CDT working with the gcc/gdb toolchain on Mac, would you mind explaining how you set up the Toolchain for CDT under project properties -> C/C++ Build -> Tool Chain Editor -> Current toolchain?

The example project from Nordic has no toolchain here and I suspect this is the cause of a bunch of build errors in the BLE proximity example app (more detail here: stackoverflow.com/.../eclipse-cdt-error-symbol-xxx-could-not-be-resolved).

Hopefully someone from Nordic can respond about your flash issue.
