Development with GCC and Eclipse: "Break at address "0xfffffffe" with no debug information available, or outside of program code."

[Rabbi]

Hi!

I have been following this process to develop using armgcc and Eclipse: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/development-with-gcc-and-eclipse

So far, I have successfully run the blinky code. However, when I am trying to run the code in "examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput" directory I am facing following issue: "Break at address "0xfffffffe" with no debug information available, or outside of program code." Is there any way around this problem?

I am using SDK version 14.0.0, GCC Toolchain 4.9 and JLink 6.40. 

Thanks!

The address fffffffe suggests a non-flashed ResetHandler address (ffffffff), my guess is that you have just flashed the application, but not the Softdevice and MBR, which are necessary for the example?

Can you please tell me how I can flash the Softdevice and MBR?

[niebert]

You find them in the SDK in the folder components/softdevice 

Next, you have to choose an appropriate version, depending on your MCU (which you did not mention). Eg. for Nrf52832, you could flash components/softdevice/s132/hex/s132_nrf52_..._softdevice.hex

However, under eclipse, it would seem that you can use this:

"For the heart rate or other BLE examples you will need to flash the softdevice by executing the "flash_softdevice" target."

I see no good reason to use an old SKD, since you begin, better work with SDK15 right away, especially since

you are beginning with this platform!

Thank you for your reply. Flashing the softdevice resolves the problem. However, I am now facing a new issue. Program is now halted with this message "Starting target CPU...". Nothing happens after that. Can you please help me with that? Thanks again.

P.S. The reason I am stuck with this old SDK is that I am trying to regenerate a custom project, which is created using SDK 14.0.0. I tried to upgrade it to SDK 15.0.0 using SES, however, that seemed to be much more difficult.

Then start a new topic for that.
