Could not determine GDB version after sending...

[Drewster]

After quite a few difficulties getting Keilv5 to work with the included examples with no responses (devzone.nordicsemi.com/.../) I decided to give Eclipse a shot.

This tutorial was helpful, except that it's a bit out-dated for Eclipse Oxygen. devzone.nordicsemi.com/.../

I used this super helpful article to fill the gaps mcuoneclipse.com/.../

Good news is.. everything builds without errors! Bad news is that I can't initiate a debug session after a version check, and I have some questions on how to flash both the application and soft device using this interface.

1. Version check issue When running Debug, with "executable" set to the ARM GDB directory, I get the following error - presumably because it's trying to check the version and can't parse the output:

   Could not determine GDB version after sending: F:\Program Files (x86)\6 2017-q2-update\bin\arm-none-eabi-gcc --version, response: arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 6-2017-q2-update) 6.3.1 20170620 (release) [ARM/embedded-6-branch revision 249437] Copyright (C) 2016 Free Software Foundation, Inc.

Is there any work-around to this? How do I disable version checks, or can I use an older GDB instance?

2)Flashing the SoftDevice The tutorial states "For the heart rate or other BLE examples you will need to flash the softdevice by executing the "flash_softdevice" target." which is less than helpful.

I see the makefile includes "flash_softdevice", but how do I actually get the debugger to run those commands via the flash tool? Thanks, Andrew

To the point 2) It runs nrfjprog whih is stand-alone command-line flashing utility (binary coming in NRFTOOLs package downloadable on Nordic web site). So it doesn't use GDB at all.

Hi Drewster

1. It seems you have a typo in the configuration of the GDB executable. Maybe you typed 'arm-none-eabi-gcc' instead of 'arm-none-eabi-gdb' ?

2. You have to set up two flash targets. One for flashing the application, and one for flashing the SoftDevice. Please see screenshots below:

You, sir, are a badass -thank you!

In this instance, I could care less if monkeys came out of the USB port to flash the device ;)

What is important to me is that I can create a debug configuration that can run "erase", flash the soft device, then flash the application code seamlessly. The existing documentation is just sparse on the "how"

Hehe, thanks Drewster. The best of luck with your project :)
